FAQs
Next, let’s see if we can answer the most frequently asked questions about TIG welders.
Choosing between TIG and MIG welders can be confusing to first-time buyers. MIG welders are better for first-time users due to their simple functionality, but TIG welders are better-designed to join thinner sheets of metal together. There’s a certain grace that TIG welders offer when working with thin materials—the welds are more eye-pleasing, but it can be tricky to operate. If you were to ask us, if you’re unsure of whether to pick up a TIG or MIG machine, why not get both in the form of the Miller Multimatic 215?
The consensus is that Miller produces the most versatile and reliable TIG welders out of all manufacturers. That said, there are diamonds-quality welders produced by its competitors, as you can see from our list (Lincoln takes the number-one spot). When in doubt, check out what the leading brand is doing, and see if what they have catches your eye. We have lists for the best Lincoln, Everlast, and Miller TIG welders that you can look at.
Without getting too technical, AC welding is a “softer” form that allows you to join thinner sheets of metal more easily. It uses less power to perform the task, thereby leaving very little mess afterward. DC, on the other hand, is used specifically for welding thicker sheets and plates. TIG welders can be DC-only or offer the best of both worlds. If you want to TIG weld aluminum and copper, make sure you get an AC/DC TIG welder.
The first and most crucial factor is welding capacity or how thick a sheet or plate of metal it can join together. The items on our list have welding capacities between 3/16 and ½ of an inch. From there, you can look at other factors, such as convenience-adding features, included accessories and equipment, and duty cycle.
Summary
After giving 45 different models a fair chance, we’re certain that you’ll find our guide on the best TIG welder helpful in your search.
We absolutely adore the Lincoln K5126-1 and recommend it to anybody looking for the best of the best, but the alternatives we provided might come in handy for more specialized welding projects.
