MIG welding is one of the most popular methods of welding among beginners. MIG welders are easy to use and can be learned in just a couple of hours. If you're looking for some advice on what would be the best MIG welder for beginners, then this article will help you make your decision!
Metal Inert Gas (MIG) welding is only one of the many welding processes that use an arc as a source of heat to weld metals. For a beginner like you, MIG welding is the perfect choice to start with. Getting the best MIG welder has a lot of advantages for someone who's about to learn how to weld metals.
MIG welding is pretty straightforward to use. Unlike with Tungsten Inert Gas (TIG) welding—which is the hardest kind of arc welding—you'll only need to point the welding gun on the metal workpiece and pull the trigger.
Most MIG welders have a wire feeder that extends automatically to the tip of your welding gun as you fire it up. This keeps the filler metal engaged to the workpiece, so you get consistent welds. With TIG, you'll need to dip a separate filler metal rod into the welding gun arc. That takes skill and precision. With MIG welding, you can complete simple projects in a matter of hours.
MIG welding can work on different levels of metal thickness. On average, the best MIG welder for the money can work on ¼ inch metal thicknesses for every increment of 250 in amperage. That's an equivalent of 6.35 millimeters. On the flip side, it can also MIG weld a 30 gauge steel at a minimum of 0.0125 inches (0.33mm). The range of metal thickness it can work on allows you to use MIG welding for various projects.
The electrode polarity is one of the many factors that will affect your welding finish. As a beginner, you may not think it's useful, but once you've worked on multiple projects, the AC/DC option will become important.
Put simply, alternating current (AC) is reversing polarity. If you use an AC option in welding, you'll get an "electrode positive"—the tip of the welding gun, which is the electrode, has a positive polarity. This positive electrode is more intense. That's why it penetrates deeply into the workpiece.
On the other hand, the direct current (DC) produces a single direction of electric current—a direct polarity. That means you get an "electrode negative" configuration. With a negative electrode, more filler metal will be melted on the workpiece, also known as a deposition rate.
Having an option to choose currents gives you more control over the result of your welding.
MIG welding isn't very technical compared to other welding processes such as TIG. The best MIG welding machine for beginners only has a few things you'll need to tweak before you start firing the welding gun. That's because these welding machines automatically adjust the amperage and, in some cases, the wire feed speed. Giving the MIG welder the precise thickness of the metal workpiece can adjust the welder's settings to make a pass on the metal effectively.
The MIG's capability to handle different metal thicknesses makes it suitable for a wide range of use in both home and industrial settings. If you'll be using a MIG welder for home, you'll be working mostly with projects involving thin steel or aluminum. But once you've improved, you can use the same welding machine for bigger projects, like repairing cars and motorcycles. You can even use this process for construction projects to put together office spaces and houses components.
MIG welding is an easy process to learn, but that doesn't mean you should go easy in choosing your first MIG welder. The right welder that fits your level of expertise will make for a fun and seamless welding experience. This is important when you're starting out. Here are some of the things you can put in mind before buying your first MIG machine.
Output dictates range. A 110-volt machine will give you fewer amperage options. Fewer amperage options mean you'll be limited in the thickness of metals you can work on.
On the other hand, you also have to consider where you'll be using the machine. If your house is fitted with 110-volt outlets, then your equipment should, too. Just get the best 110V MIG welder In scenarios wherein your hands are tied when it comes to power options. But if your working area has 220 volts or higher, you should get a MIG welder that can adapt to both 110v and 220v and set electrical currents to either alternating current or direct current.
You don't want something that is too powerful or too weak.
At the beginning of your MIG welding journey, you'll be taking on small home projects. Your inclination to do projects may not be as frequent. A smaller machine is your best option.
A portable welding machine will not need a lot of tweaking compared to the larger ones with many features. This is important when you're a beginner doing garage projects as you want to focus more on perfecting your welding technique. As you refine your skills, you'll notice subtle details on your welding finishes. Your progression will naturally elevate you to more complex projects, and it follows that your preferences will change. You'll go from a light MIG welding machine to a heavier, multi-process one that offers more controllable features. So, don't rush the progression. Start small and buy a small MIG welder first.
Apart from skill, you'll also need to consider how much you're willing to pay for a MIG welder. The best cheap MIG welder should be in the lower price range, at around $500, but it should also offer decent features.
It wouldn't be hard to find these kinds of cheap MIG welders loaded with features. The competition from each manufacturer has driven everyone to put a lot of features into a machine, and the price is low. It's all a matter of selecting what you think works best for you.
The Lincoln Electric K2185-1 is a great example of a cheap, portable MIG welding machine with enough features. It can be dual-process—compatible for both MIG and flux-core welding. It also supports mild steel for your initial home projects. Most importantly, it only costs $465.
Warranty is important when you're planning on doing a lot of welding. If you're going for low-priced ones as your starter welder machine, it has to offer an excellent warranty. We're not just talking about duration. The service within the warrantied timeframe is also very important.
For example, if there are malfunctioning components on the MIG welder, the manufacturer must offer basic troubleshooting before replacing the parts, free of charge. But what's even better is if they can troubleshoot over the phone and even send the parts to your address so you don't have to carry your machine to the service center.
Companies such as Lincoln and Miller provide these kinds of excellent warranties on their welding machines for 30 days to as much as 5 years, depending on the type of machine you purchase.
Having that MIG welding machine in your workshop for the first time is an amazing thing. That feeling of unwrapping your first MIG welder that looks shiny and perfect will make you want to fire it up and play with It immediately. Rein yourself in a little. Check out these tips first before you set out to do some badass MIG welding.
