We can engage in many hobbies that are worth our time. Some choose to spend their free time playing sports while others do leisurely activities like shopping or watching movies.
One hobby that is not that famous but is equally exciting as any other pastime is welding. Through welding, you can build numerous things, and only your imagination is the limit. Some hobbyists weld to create home furniture while others create works of art. Some extend their hobby to helping others by opening a small shop. They repair small equipment or machines as big as boats and cars.
No matter where you fall in these classifications, you will be looking for one thing—a reliable machine to perform your tasks.
If you are into tungsten inert gas (TIG) welding, you’ll need a TIG welder machine. In this article, we will share our top pick in the pool of equipment available in the market today. But before that, let us first refresh our knowledge on TIG welding and everything in between.
What Is TIG Welding?
Also known as gas tungsten arc welding, TIG welding is one of the most well-known welding methods because of its clean and excellent output.
However, it will take you lots of practice to perfect TIG welding because it involves a more complex process than other welding techniques.
TIG welding uses tungsten electrodes to create the weld, hence the name. It uses argon as the shielding gas to ensure that no other elements can enter the weld and make it imperfect. Helium can also be an alternative, and this process is called heliarc welding.
This welding method can also weld more types of materials such as steel, stainless steel, metal alloys, and non-ferrous metals. This characteristic makes TIG welding even more popular with professional welders and hobbyists.
Our Recommendation: Miller 110V TIG Welder Diversion 180
If you want to give the Miller brand a try, you can begin with the Miller Diversion 180 TIG Welder. This machine is perfect for hobbyists and small-scale projects and repairs. Nonetheless, you can still use it for various heavy-duty tasks.
- You can set it up in three easy steps.
- Highly portable TIG welder weighing only 50 lb, perfect if your work is on-the-go
- The machine can use the following input voltages with the suitable plug: 110/115/120 V, 208 V, and 220/230/240 V.
- Has an inverter-based source of power, AC and DC
- Has a fan for the machine cooling system
- Ensured shielding thanks to the auto-post flow technology and high-frequency weld
- You’ll have the Weldcraft A-150 TIG torch included in the kit.
- You’ll need to practice using the pedal for power source control because you’ll be using both hands in TIG welding.
- Disuse of the machine can cause malfunction, so it is better to use it regularly.
- The built-in fan may contribute to contamination of the weld.
- If you are used to manual TIG welders, you’ll need time to adjust to this machine’s digital technology.
How Diversion 180 Creates the Perfect Weld
Who does not want a perfect weld? The metals you are joining will be sturdy. Also, aesthetically speaking, the appearance of your weld will be smooth and clean.
You’ll often hear the word “penetration” in TIG welding. The deeper the penetration, the better the connection between the welding materials.
Polarity, electrode diameter, travel angle, shielding gas, travel speed, contact tip-to-work distance, and voltage all play a role in creating a perfect weld. Let’s check the performance of Diversion 180 using these factors.
|Factors Affecting the Perfect Weld||Miller Diversion 180 Performance|
AC and DC are the polarity indicators in welding, with DC having stable polarity and AC having a changeable polarity. Your use of AC or DC defines whether you’ll have effective penetration, less spatter, and better control of the arc.
|You can use both AC and DC for Miller Diversion 180, which will allow you to adjust your amperage lower for thinner materials and higher for thicker ones.|
| Electrode diameter|
The smaller the diameter of the electrode, the deeper the penetration because of the better concentration provided by the smaller electrode compared to larger ones.
|Electrode diameters of Miller Diversion 180 range from 1–6.4 mm, depending on whether you are using AC or DC electrode negative. For instance, using DC with an amperage of 15–40 requires a 1-mm electrode diameter, while a 750–1000 amperage using DC requires a 6.4-mm electrode diameter.|
| Travel angle|
When it comes to travel angles, there is a simple rule. If the electrode is perpendicular to the material welded, the penetration will be deeper. Nonetheless, technology has made it possible for a welding machine to provide the same penetration no matter what the welding angle is.
|Miller Diversion 180 is a tool you can rely on whether the material you are welding is flat, perpendicular, or curved.For perpendicular positions of materials, a 45-degree angle is best.|
| Contact tip-to-work distance|
After the angle is the distance of the torch tip to the material being welded.Here is the ratio: the farther the contact tip-to-work distance, the shallower the penetration. The current, which produces heat, increases the closer the distance. As a result, melting will be faster, and penetration will be deeper.
|Adjust the torch distance depending on your goal.|
| Travel speed|
Electrode travel time is also a factor in creating perfect welds. The faster the electrode travels to the metal sheet, the deeper the weld.
|To get the result you want (i.e., faster melting for deeper welds or slow melting for bending and shallower weld), adjust the distance of the torch. The farther it is, the slower the electrode’s travel speed. Conversely, the nearer the torch, the faster the electrodes will travel to the material you are welding.|
| Shielding gas|
You have two choices on shielding gas when it comes to TIG welding. Argon will give you less penetration, while helium gives deeper ones.
|Manufacturers suggest the use of argon gas to see high-quality weld results.|
Voltage capacity defines the amperage a machine can produce. You need to set the amperage correctly depending on the material you are welding.
|The Miller Diversion 180 is capable of producing 10 to 180 A.For instance, the Miller 110-volt TIG welder will create less penetration compared to the Miller 120-V TIG welder. The difference may not be significant with tighter gaps, but if you switch from 110 V to a higher 220 V, you’ll see the difference.|
So, after knowing these factors for a perfect weld, let’s answer the question, “What makes Miller 110V and 220V TIG welder—and the Miller brand in general—an excellent choice?”
