Choosing the appropriate cutting or styling equipment for your project can significantly impact the outcome. To achieve greater efficiency and safety in your welding process, you must be careful in selecting the appropriate cutting that can cut through metals.

Cutting torches typically generate positive pressure and are used at identical pressures of both acetylene and oxygen. These single-hole copper-alloy tips are connected to a torch grip that has a mixer. It then combines the fuel with the oxygen, similar to how a car fuel system blends gas and air.

Read on and learn the cutting torches and tips you can use for your next welding project.

Oxy-Fuel Welding and Cutting

The oxy-fuel welding or oxy welding is a method of utilizing fuel gases and oxygen to cut and weld metals. Oxy-fuel has been considered one of the oldest welding and cutting techniques, and acetylene is the most commonly used fuel gas for this process.

Torch tips are very important for cutting, heating, gouging, and brazing and are usually made from tellurium copper with a precision swaged calibrated orifice. There are many types of regular and special cutting tips and welding nozzles.

It is hard to imagine industrial construction without plasma cutters. These tools make it possible to accurately cut and process different types of steel used for construction. The metals you see on a high-rise building or the ones used to repair automobiles are products for plasma cutters. 

There are giant plasma cutters for big-scale industrial construction and portable ones compatible with homes for all-around repairs and hobbies. In this article, we'll share an overview of how plasma cutters work and some essential safety tips so you can work with your projects injury-free. 

The Fourth State of Matter: Plasma 

Before you get too excited and wield a plasma cutter, let's know first what plasma is. Types of matter can change their state through the induction of high energy. For example, solid matter can transform through high heat into liquid, and as the heat continues to rise, the liquid turns into gas. 

When gas is inducted with the highest heat level, it becomes ionized gas, which we call plasma. In this state, the gas becomes electrically conductive, which workers use to cut metals used in different manufacturing processes effectively. 

There are three essential components of a plasma cutter: 

Setting Up the Plasma Cutter 

Now that you know how plasma came to be, it is important to know the different components of the tool. Then, setting up your tool and cutting metals is fairly easy. Here are five quick and easy steps to operate your plasma cutter. 

Step 1: Attach the plasma cutter to an air compressor. There are 20-gallon tanks for quick work, but larger capacities are better if you intend to work for long periods and thick metals. 

Step 2: Connect your plasma torch to a power source. Most plasma cutters require 220V or 415V. Ensure the power source in your workstation is compatible with your tools for it to run properly. Otherwise, use a power adapter. 

Step 3: Attach the ground clamp to the plasma cutter. Don't miss this step, for this is a safety precaution that avoids grounding and electrocution. During work, when the ground clamp is detached or loosens, the machine shuts down to prevent accidents. 

Step 4: Prepare the plasma torch. Make sure to attach all consumables needed to do your work. Also, ensure that you have spare consumables within reach if you run out in the middle of your cutting job. 

Step 5: Set up the proper amperage for your activity. Plasma cutters usually come with a settings chart to tell you the right output depending on the material's thickness. After all this preparation, all you need is to pull the trigger on the plasma torch to start cutting metals. 

Safety Precaution When Using Plasma Cutters 

Construction tools may be hi-tech, but they also come with hazards. That's why only professionals are allowed to handle such things as much as possible. 

Now that you know how plasma cutting works, it's also essential to cover some safety precautions when using a plasma machine. Here are some important safety notes you need to remember. 

Wear Eye Protection 

Like welding, plasma cutters produce intense flares that could damage your eyes when you look at them directly. If you are uncomfortable with a full helmet, you can invest in dimmed eye goggles for plasma cutting. Furthermore, if you are in a shared workstation, having your goggles on would make the people around you to be cautious. 

Proper Work Clothing 

You can't wear casual clothes during your plasma cutting job. Your cotton shirt and jeans are more likely to be caught on fire because of the high heat the torch tip produces. There are safety clothes proper for welding and plasma cutting. Make sure to invest in fireproof boots, coats, and gloves

Moreover, throw in some protective earmuffs to complete your ensemble. Plasma cutting torches create a loud noise, and over-exposure to these noises can affect your hearing. So, don't forget to put on and invest in protective clothing. 

Never Work on Wet or Moist Areas

It's a big no to operate plasma cutter on wet areas. The machine requires a high voltage of electricity to run. A faulty wiring can cause grave accidents. 

Instead, invest in a plasma cutting table. It gives you a safer safe place to work in, and you can work in a more comfortable position. Check out how plasma cutting tables work and have some that suit your needs. 

Keep Away From Flammable Materials

Operating plasma torches involving flying sparks. So anything flammable should be kept away from your workstation. Flammable material also includes gases and chemicals that can react to the hot plasma and spark emissions that could burst in contact. Ensure there's nothing dry, flammable, or leaks when working with plasma cutters. 

Never Work With a Faulty Machine 

Some accidents are due to the user's stubbornness. If the machines are already faulty or you can hear creaking sounds, it is best not to use them. Instead, have them checked by experts for proper assessment. 

Don't repair your tools by yourself unless you have extensive plasma cutting machine maintenance knowledge. It's better to opt for another plasma machine or invest in a newer and better model. 

Final Thoughts 

It takes a professional to navigate how plasma cutter does work. In addition, it takes extensive training in proper handling and basic knowledge of the tool for you to wield it properly and safely. We hope this overview of the steps and preparation helps you handle your plasma cutters better. Also, keep in mind these safety tips so you can work away injury-free. If you need more reviews on tools such as welding machines, plasma cutting torches, welding accessories, and different safety gear, subscribe to our blogs for information.

What You Need to Know

You're in the middle of a welding project when you notice that your welds are starting to look a little uneven. Upon closer inspection, you realize that you've been inadvertently causing welding undercuts.

Welders know that the undercut is a defect that should be avoided, but it's often hard to do so. Undercuts are common issues that can occur when welding. However, it can lead to some serious consequences if not remedied. This blog post will discuss the types of undercuts, the consequences of welding undercuts, and how to prevent them. We hope this information helps you avoid any damage to your project!

A Closer Look at Welding Undercutting

Welding undercut happens when the molten welding pool metal does not completely fill the welding joint, resulting in a groove parallel to or near the weld metal. As a result, you can incur undercuts on your entire weld or portions of your weld. It is often caused by welding too quickly or using too much heat, resulting in the welding pool unable to penetrate the entire metal plate thickness.

Types of Undercut

There are two different undercuts types, and they show up in unique ways.

Also known as a crown undercut, this type of undercut happens at the toe of your weld. External undercuts can occur when you join two metal pieces together at an angle (often at 90 degrees). This process is also known as a fillet weld.

Also known as root undercut, you will find this welding defect at the root of the weld or the bottom-most part of your weld. Welders will often find this type of undercut in butt welds, a process where you weld metal ends without overlapping them.

How to Use a Welding Undercut Gauge

If you see pits on your weld, does it mean it's a weld defect and you'll have to start from scratch? According to AWS, undercuts are acceptable if these conditions are met:

Thus, a weld gauge is a must-tool that every welder should have in their arsenal, so you can accurately measure undercuts or pits. 

To check how big or small an area of an undercut is:

Effects of Welding Undercutting

You can imagine your weld with undercuts like the worn-out roads with holes. If cars pass or it rains, the holes trap liquid and dirt, creating bigger holes. It's the same idea for your parent metal. Undercuts cause metal fatigue strength and speed up corrosion in your weld. 

Another effect is if the undercut is more than 6mm deep, it can compromise the joint's structural integrity and lead to cracking under loading and pressure. 

Like any welding defect, undercuts shouldn't be overlooked as they will cause large accidents if the undercut weld is used for infrastructures such as bridges or buildings. If you suspect that your welding equipment may be causing a welding undercut, it is important to have it inspected by a qualified welding engineer. 

Prevention Tips for Undercutting

Welding undercut can be prevented by following proper welding procedures and using quality welding equipment.

Be Comfortable

It's incredibly important to have a level welding surface to maintain the correct direction of motion, drag angle, and weld bead consistency. This will help you to produce a quality weld every time.

Make Sure You See Your Weld Metal

Welder's helmets that don't have auto-darkening features are difficult to use because the welder has to keep taking the helmet off to see what they're doing, resulting in welding defects such as undercuts or burns.

Get the Right Arc Length

Controlling your arc length is extremely important. Welding too close or too far away from the weld puddle will result in welding defects. An indicator that your arc length is incorrect is welding spatter. When the welding current is too high, it causes molten metal to spatter. Another indicator of an incorrect welding arc length is welding resistance. When welding, you should maintain a consistent welding speed. 

Lower Your Current

If instead of portions, you see long lines of undercuts, we suggest that you reduce your current. This will decrease overheating and help you get proper fusion—it also improves your welds’ appearance. Using a lower welding current can create a cleaner weld that is less likely to have imperfections. 

Consider Which Electrode You Are Using

While deeply penetrating electrodes are necessary for many applications, the welder needs to be mindful of their technique to avoid welding undercuts. If the arc length is too far or the weave width is too wide, welding undercuts will almost certainly be present in the weld. 

Some electrodes—with stick welding, for instance—are naturally more prone to undercutting than others. The welder needs to be aware of this and use the correct electrode for the application. 

Allow the Base Metal to Cool

You must be aware and patient when heating the base metal if you're welding. It will warp or distort from excess heat. You need to weld in small segments and then let the metal cool down for 5–10 minutes between welding. The waiting period will vary depending on the material and welding tool you use. If you're not sure how long to wait, err on the side of caution and give it more time to cool down. Otherwise, you risk ruining your work with a welding undercut.

Pause on the Weld Puddle

Welding takes a lot of patience and a steady hand, especially if you want to avoid welding undercuts. Undercuts can happen when the welding bead does not travel in the leading 1/3 of the weld pool, resulting in the heat from the arc being directed towards the molten puddle instead of the weld itself.

Welding undercuts can be minor or severe, and unfortunately, they can also lead to bigger welding problems like weak welds. Fortunately, you can prevent undercutting and other welding defects by paying attention to your welding equipment, technique, and speed. With a little practice, you'll be welding like a pro! 

Therefore, it's important to know the different types of undercuts, use a welding undercut gauge, and know what to look for when inspecting your welds. Check out our other blogs for more informative reads on welding.

We rely on roads and transportation for faster service and production. Heavy metal construction and road services are essential for day-to-day operations. Excavators, automobiles, skyscrapers, robots, and footbridges are essentials that require accurately constructed metals. Metals are naturally durable, making them the best choice for almost anything that needs to be particularly strong and sturdy.

The irony is that the power of metal is also its weak point. Metals are resistant to damage, and they are extremely difficult to modify and shape into specialized pieces. How then do professionals accurately cut and modify metals required to construct something as huge and strong as an airplane wing? For most cases, the plasma cutter is indeed the ultimate solution. The plasma cutter may seem like something out of a science fiction novel, but it has been a common device since World War II.

A plasma cutter has a very simple concept. It accomplishes its goal by utilizing one of the universe's most common states of matter. Keep reading to know more about plasma cutters and the powerful machine called the Hypertherm Powermax 65.

Peeking Inside a Plasma Cutter

Plasma cutters emerge in several different forms. First, there are monstrous plasma cutters that produce accurate cuts with robotic arms. There are also portable, handheld units available in a handyman's shop. Irrespective of their size, all plasma cutters perform the same functions and are built on a similar design.

Plasma cutters operate by passing a compressed gas—like nitrogen, argon, or oxygen—through a central tube. A negatively charged electrode can be positioned in the center of this channel. A circuit is formed once you impose energy on the negatively charged electrode and touch the metal with the nozzle's tip. In between the electrode and the metal, a strong spark is produced.

The plasma itself produces electricity and the arc creation process is constant as long as power is applied to the electrode. The plasma should remain in contact with the metal object you are working with. The cutter nozzle does have a second nozzle to secure this contact, guard the cut against oxidation, and control the unpredictable nature of plasma. These channels circulate a steady stream of shielding gas around the metal surface. The gas flow’s pressure completely controls the radius of the plasma beam.

Plasma cutters are now commonplace. They are used to personalize, modify and create chassis and brackets in tailored machine shops and automotive manufacturers. Building contractors use plasma cutters to cut and fabricate massive beams or metal sheets goods in complex projects. Locksmiths utilize plasma cutters to drill into safety deposit boxes and vaults when customers are locked out.

6 Things to Think About When Selecting a Plasma Cutter

Plasma cutters are one of the most effective methods for cutting metal parts such as steel, alloy steels, bronze, and aluminum. If you're looking for a good plasma cutter, these are the attributes you need to keep an eye on:

Air Compressor

Plasma cutters require pressurized gas supplied by an installed air compressor or an external compressed air supply. Each of these generates excellent results, but when selecting a plasma cutter, you must consider which is the most advantageous for you. For example, a built-in compressed air will be more costly, but it allows you to manage small jobs better.

Arc Pilot

A pilot arc is a trimming feature that enables you to cut metal without the torch's tip touching it, resulting in a much more steady arc with a longer consumable existence. It is useful when cutting rusted metal parts because it eliminates the need to clean the whole metal.

Rating Reduction

The width of metal that a plasma cutter can cut is another crucial factor to consider. Recognize the total thickness of metal you'll be working with and select a device that can handle it. A plasma cutter has three different cut settings: rated, quality, and severe cut.

Torch for Cutting

The size of the torch is essential. If you're dealing with a large workshop, a longer torch will allow you to work in different areas of your working space without needing to relocate the heavy plasma cutter around.

High Cut Quality

The cut performance refers to how clean and professional the final cut is. Because the best plasma cutters have such a high cut quality, cuts will be accurately sharp and clean. It will also give you more time to do other welding-related tasks since you won't be spending time cleaning up the mess to get a smoother surface.


When selecting a plasma cutter, you want to have high-quality equipment that will last a long time. Plasma cutters are not cheap, so ensure your investment will last and won’t break down while you're operating on something significant.

Select a reputable brand from a reputable retailer. Brands such as Hypertherm, which some professional welders highly recommend, are available on Amazon.

Hypertherm Powermax 65 Hand System

Here's What You Should Know About The LTP5000D Before You Buy It

Don't expect too much from this plasma cutter. You can't bank on immaculate performance, durability, or a clean-cut for the price.

However, if your job will not suffer due to the limitations listed below, the LTP5000D is of great value.

Cut Cleanliness

Given its low price, this plasma cutter performs decently. However, many people expect an unblemished cut. Unfortunately, the LTP5000D can only do fine cuts on thinner metal sheets. So be aware of this and don't be surprised.

While the spec sheet claims a clean cut for up to 1/2 inches, there will be residue at the newly produced edge. This residue can be removed using a simple file or, in certain cases, an angle grinder, depending on the speed of travel.

If you don't anticipate it to function as well as a Hypertherm or a Miller machine, you'll be pleased and content with this low-cost option. Just remember that when you are cutting anything thick, be careful and make sure you file down the edge.

Characteristics of Arc Behavior

When cutting with this device, expect that there will be a lot of sparks. As a result, you should avoid working near anything you don't want to cover with them.

The aperture opening at the torch's tip appears to be too big. The plasma arc becomes less focused and wider as a result. Due to this, the cut will be thick, and the metal, especially the thick parts, will flash up like fireworks.

A wide-cut means lesser precision, which ties in with the earlier argument about how this unit can't compete with brands that cost higher. Plasma cutters and associated torches are extremely complicated machines. Lotos' cost-cutting efforts are admirable, but you can expect erratic arc behavior and less precision when buying this low-cost machine.

If you want or need more precision, purchase a plasma cutter from a more trusted brand.


The LTP5000D is a fairly good Lotos plasma cutter that will not break the bank. As a bargain brand, Lotos has weathered the test of time. You'll be happy with this cutter as long as you have realistic expectations and don't require a machine for high-quality work.

You would never think of rugged and noisy machines such as plasma cutters to create intricate works of art. But plasma cutters are useful not only in construction sites and factories but also in cozy homes and galleries, the common birthplaces of heavy metal art.

Generally, plasma cutters aren't difficult to use as long as you know the basics. It's pretty straightforward—electrically heated plasma cuts through metal and steel like butter. But let's explore the exciting ways of using portable plasma cutters in the art industry.

The Big Picture: Plasma Cutting Machine Explained 

Plasma cutting is one of the most advanced cutting techniques today. You can use any conductive material such as metal, steel, copper, and brass for plasma cutting to get efficient and precise cuts for any field.

How do we use a plasma cutter for metal art? The plasma cutter superheats gas (creating plasma) and blasts it through the nozzle. The nozzle is crucial in your plasma cutter machine as it produces an electric arc to make cuts.

Of course, there is a learning curve to using this machinery, but once you get past it, you can make a clean cut effortlessly.

Portable Plasma Cutting Machine Benefits 

The best plasma cutter's setting and ease of use are incredibly greater compared to an oxy-fuel cutter. For one, plasma cutters provide for diversity, allowing you to work on different types of metals. In contrast, oxy-fuel cutters can only cut through iron-containing steel. In addition, plasma cutters can cut through stacks of metal plates as if they were pancakes, while oxy-fuel cutters can only cut up to 24-inch-thick steel. 

Safety is another thing that piques artists to get portable plasma cutters since the gas used on this machine is not highly flammable. As a result, it's far less dangerous than using other cutters. 

Last but not least, a portable plasma cutter makes cutting different shapes and angles more accurate. Simple welding or torching cannot produce the same results as plasma cutting.

If you are a metal art creator or enthusiast, you should be on the lookout for these cutting-edge plasma cutters.

CUT50D 50A Air Inverter Portable Plasma Cutter with Non-touch Pilot Arc

The CUT50D 50A Air Inverter Portable Plasma Cutter features a lift-type arc start for drag starts and cutting. The closer your cutter is to the metal, the finer and more precise cuts you will get. 

You can cut sheet metals as thin as 22 gauges nicely with its lower-limit output of 20 amps. It's perfectly lightweight and powerful for any DIY workshop project.

What's interesting about this cutter is its non-touch pilot arc, which allows you to work on your metal canvass with minimal slag. It means you don't have to put your torch too close, producing a higher quality of cuts and longer consumable life.

CUT50D 50-Amp Portable Plasma Cutter

This cutter comes a tad cheaper than the CUT50D 50A Air Inverter Portable Plasma Cutter, but make no mistake: it’s no less powerful. 

Incredibly versatile and affordable, this 50-amp portable plasma cutter can go through a half-inch-thick metal in one pass when running on 240 volts. If you're working with a lower voltage—say, 100 volts—you can go up to 40 amps to cut a ¼-inch-thick plate. You can even go as low as 10 amps for thin sheet metals used for auto body works or bendable materials for rendering curves in your work.

Is Plasma Cutting Perfect for Your Art Project?

The metal you work on certainly affects whether or not you should try plasma cutters. Since every type of metal works for this dynamic machinery, you should consider the thickness of the metal

Apart from that, let us ask you a few more questions to help you decide if plasma cutters will work for you.

Hopefully, the list helps you narrow down your choices and find a high-quality portable plasma cutter to satisfy your artistic needs.

Cutting Techniques 

Thermal dynamics has brought to life tons of metal art pieces. But how can you, a beginner, start using this overwhelming technology? Here are some mind-blowing tips. 

Making Straight Lines 

Portable plasma cutters are heavily dependent on the skill of the welder. So if you happen to have shaky hands, cutting a straight line through the metal can be tricky.

That shouldn't be a problem. You can clamp rulers or straight edges onto the metal, so you can just easily trace and make immaculately straight lines without breaking a sweat. 

Making Precise Drawings 

Are you a metal artist just for the fun of it? You may not be as gifted as the European sculptors behind giant-sized falcons or angels, but that's perfectly fine. We all start somewhere, and it always begins with templates.

Metal artists use projectors to cast their desired templates onto the metal. Depending on how near or far your projector is, you can resize your projected templates. Of course, if you don't have a fancy projector, you can use wooden templates, but these are one size only. 

If you didn't know how to draw a bear on your metal sheet back then, now you do! 

Making Smaller, Cleaner Cuts 

It is important that every plasma cutter, portable or not, has its consumables properly maintained and changed every so often. You can make cleaner and far more precise cuts with new nozzles and tips than with burnt-out ones. 

In addition, double-check if your consumables are compatible with your plasma cutter and can handle the amps. If you're cutting at 50 amps and your consumables can only withstand up to 30 amps, you'll burn through them more quickly.

Making Longer Cuts 

Most artists always make a sketch or light drawing first before making a definite stroke on paper. The same practice applies to plasma cutting.

Dry runs can give you an idea of how far along you'd have to reach when cutting. Because if you happen to stop in the middle of cutting your metal, the cut would be uneven. 

If you end up with a small hole where you restarted the cutting, just fill it in with a tack weld and grind it back.

Lincoln Electric provides reliable cutting tools for every curve, odd shape, and interesting cuts you want. The company has provided quality plasma cutters for years and is continuing to innovate

Luckily for you, this article narrows down Lincoln plasma cutters from A to Z. So, let’s check out Lincoln’s product lines and see what you can bring home to your workshop today. 

Types of Lincoln Electric Plasma Cutter 

Lincoln Electric has developed a wide range of plasma cutters for every consumer, from construction and autobody professionals to DIY hobbyists at home. 

People use Lincoln plasma cutters in light and heavy industries for those seamless and quick cuts of much-needed sheet metals. But which cutting machine works best for you?

Here are the types of Lincoln plasma cutter machines with their significant features. 

Handheld Air Plasma Cutters

Portable plasma cutters are popular due to the increasing demand for portable cutting machines. 

They’re not exactly lightweight, but at least they’re a great improvement on industrialized plasma cutters. Each plasma cutter offered by Lincoln is easy to operate with its Touch Start System and safety features for the proper installation of consumables and torches.

A handheld Lincoln plasma cutter comes with an air compressor, hand torch, consumables, and other accessories. Lincoln offers four portable plasma cutters:

Tomahawk 375 AIR Plasma Cutter with 10 ft. Hand Torch Tomahawk 625 Plasma Cutter with a 20 ft. Hand Torch Tomahawk 1000 Plasma Cutter with 25 ft. Hand TorchTomahawk 1500 Plasma Cutter with 25 ft Hand Torch 

Mild Steel





These portable plasma cutting machines may not have the longevity and capacity as its big brothers, but it gets the job done. 

Mechanised Air Plasma Cutters 

This is what you could call the conventional plasma cutters—the ones that you see at your friend’s home garage or professional production workshops

These types of Lincoln plasma cutters use only air and oxygen for cutting, unlike high definition plasma cutters. They may not provide excellent cut quality, but they have the fastest cutting speed. These work best when cutting mild steel.

Here is a brief overview of Lincoln Electric’s conventional plasma cutters: 

Max. Cut Capacity (inches)
FlexCut 80FlexCut 125FlexCut 200
Mild Steel1.251.502
Stainless Steel11.502
Aluminum 11.501.50
Gas Pressure87–109 PSI90–120 PSI90–130 PSI

You can also opt to buy cutting tables with your mechanized air plasma cutter. It is highly suggested since these machines are already intended for light industrial use.

High Definition Plasma Cutters 

We’re not talking about HD TVs here. We’re talking about high-end cutting with fewer excess metals. This plasma cutter is perfect for those large, more demanding applications—like in the construction, recycling, and automotive industries. 

HD plasma cutters can keep you operational 24 hours a day, unlike small to mid-sized Lincoln plasma cutting machines.

There are two Lincoln Electric products under the Fineline line:

Gases used for your plasma cutters are collected through the plasma cutter’s compressor. In addition, some welders use gas tanks filled with the gases needed to make them more concentrated. 

That said, plasma cutter gas is an integral component of your plasma-cutting process. Mixed gases can give you cleaner and faster cuts. However, they come with a safety warning. So make sure you have the right tools and equipment to maintain these huge plasma cutters.

CNC (Computer Numerical Control) Plasma Cutters 

Do you remember those cool cutting machines from the first scene of the 1999 classic robot movie, Bicentennial Man? Fine line cutting brought that robot to life. Plasma cutting used to be fictional, but now, we have Torchmate CNC plasma cutters, one of the most advanced plasma cutters of Lincoln Electric. 

What’s convenient about this technology is that it comes with a downdraft, also known as a water table, and software that lets you draw on any metal without ever holding the torch itself. 

You can do the cutting manually by using the arrow keys on the plugged-in computer. In addition, you can add the metal thickness and the amps you need to do your cutting. 

We've taken the liberty to jot down Lincoln Electric's Torchmate products. These products have a downdraft, a cutting table in different sizes, and a plasma cutter of your choice. It's a one-stop shop for your plasma-cutting needs. 

Torchmate 4400

This product has a 4x4 cutting table that's perfect for small spaces. In addition, it is fully assembled, meaning you or a technician doesn't have to set up your plasma cutter.

If you're a professor teaching engineering and any related field to plasma cutting, then having this product can be quite handy for classroom discussions. 

Torchmate 4800

It has a 4x8 table that's also fully assembled. If you happen to work in a medium-scale fabrication shop, this is what you want. 

Torchmate 4510

Another cutting table that suits well with mid-sized production. This 5x10 table will surely fit into your shop nicely.

Torchmate X5x10 

It is designed to cut thick metal plates and endure harsh shop environments. Recyclers and construction workers will appreciate this product. 


This plasma cutter has a table that goes up to 8x22, perfectly paired with a Lincoln HD plasma cutter.

People are attracted to buying things that they perceive to be of high value, despite their high price. This principle works the same for welders, but it’s not always the best decision.

A cheap plasma cutter can save practical welders a lot of money, but the experienced ones also see low value associated with the low price, which prevents them from buying it. As a welder, you can relate to these common and valid reasons.


The lifespan of a cheap plasma cutter is one of the primary concerns for both home hobbyists and professionals. Low-cost means the cutting equipment is assembled using substandard components and will wear out quickly when used frequently.

Risk and reliability

Associated with the substandard quality of the cheap plasma cutting machine is the worry it may not work as it's expected to. If you ever felt that irrational fear of a cutting machine exploding in front of your welding helmet as soon as you flip the switch, you're not alone. It's a perceived risk due to the lack of reliability associated with the cheap machines.


Another common reason that repels many welders from cheap cutting rigs is that they may not produce quality and smooth cuts as the branded, expensive ones. They are low-priced, so the machine must not have specifications that can compete with the mid or high-priced, branded ones, with sub-par functionality.

Expensive Versus Cheap Plasma Cutters

To know whether our reasons for avoiding budget plasma cutting machines are serving us well, we have to look at its characteristics and compare it with the one that carries a popular brand. This way, we can find out how wide the gap is between a branded machine and a cheap, generic one. 

CharacteristicsPlasma Cutter (Cheap)Plasma Cutter (Branded)
Dimensions16.9 x 13.7 x 11.6 inches18.1 x 7.9 x 12.6 inches
Weight20.8 pounds22 pounds
Voltage110/220V at 50/60Hz110/240V at 50/60Hz
Current Range20A–50A15A–40A
Rated Duty Cycle60% -50A100%- 40A40% - 40A 100% - 20 A
Clean Cut10 milimeters12 millimeters
Severance Cut14 milimeters25 millimeters


The cheap one wins this, hands down. The sample above reflects close to what most generic plasma machines cost—around $150–200 for a package that includes the machine and other accessories. The price of the cheap machine is very competitive versus the branded one, which is usually nine times more expensive.

Size and Weight

A portable plasma cutter is common today. The size will be small enough you would mistake it for the small briefcase. This is true with two of the comparison machines above. Both the generic and branded cutters fall within the comfortable range for portability, but in terms of bulkiness and weight, the cheap one is smaller and lighter to carry around your workshop than the branded ones.


Both the sample generic and branded machines are neck a neck when it comes to specification. However, there are a lot of similarities with a few characteristics where either one wins. For example, the dual voltage and the output current range are almost the same.

In terms of cutting capacity—the most valued characteristic of any plasma cutter—the branded one closes the deal with a maximum of 1-inch thick metal cutting capacity. On the other hand, the generic plasma cutter is very close. This is notable, especially for casual cutting activities.

Advantages of Choosing A Cheap Plasma Cutting Machine

The functionality of the cheap machine doesn't differ as much from branded, expensive ones. In addition, it also extends a lot of practical advantages to the prospective welder if they buy one. Some of the highlights of a cheap plasma unit are stated below.

It can last long, but it's also easy to replace. 

Anything that is taken care of can lasts long, and that includes the best budget plasma cutter available. But let's say you've been busy using the low-cost cutting machine and you forget to check it for damages, and one of its essential parts gets broken—the cutting torch. You can easily replace the torch with the same generic brand because it didn't cost you that much to buy the whole package. Time-wise, the replacement option would be more practical rather than spending effort repairing the torch.

On the flip side, a branded torch is harder to replace because it costs more. Buying one cutting torch will cost you as much as a whole cheap plasma cutting machine package, with the cables and consumables. You'll be better off buying a cheap one and selling your pre-loved branded cutter for welders with money to burn.

Cheaper and more accessible consumables.

An inexpensive plasma cutter doesn't require much in terms of consumables. You can easily get a spare at most shops. That's because the consumables are made of basic materials and designed with only the essential technology needed.

Branded cutters manufacture their own high-quality, long-lasting consumables, but they are still replaceable. It's also more expensive to buy them. The branded consumables are advantageous to welders who are looking for a longer duration and frequency of use. So if you're using your cutter for occasional projects or work, you'll gain a leg up with a budget plasma cutter.

Can also cut thick metals well.

Cheap cutters don't cut as deep as high-priced ones. But that doesn't mean it can't cut thick metals at all. Most cheap plasma cutters can cut through half an inch of metal with ease—just the right thickness for most everyday welding and cutting. So if the majority of your work involves tearing apart metals of the same or lesser thickness, a cheap cutter will do just fine.

It's non-exclusive.

One pain point with branded welding and cutting products is that they tend to fit only the manufacturer's components. The bundling and unbundling strategy make a lot of sense from a business standpoint, but not to a wise welder who's pinching pennies.

The beauty of cheap cutters is that they’re generic. Parts and components can be bought from another generic manufacturer or even a branded one. As long as it fits the machine when you plug it, you'll be set. On the other hand, we advise you to limit this to accessories that can be attached, like the leads, cables, hoses, and torches. Please check the similarities of the components you're going to substitute before plugging it in. And we advise you to still get the internal machine components from the manufacturer or its authorized dealer even if another generic manufacturer offers the same exact component.

Conclusion: Plasma Cutters Are Cheap, but They Work

Welders are often inclined to buy the best cutting rig for the first time. This is a wise practice, especially if they're still in the learning and experimenting stage. But that doesn't always have to be the decision once the expensive plasma cutter has lived out its usefulness. It's good to have the courage to try something new, something cheap but practical. So go for the cheap cutter, and it may be the only one you'll keep buying for the rest of your welding career.
