A good TIG welder for stainless steel tubing is an AC/DC inverter power source that delivers clean, controllable direct current (DCEN, or straight polarity), starts the arc without touching the tungsten, and lets you hold a stable arc from roughly 5 amps up to full output. For tube work, the four specs that actually decide … Read more
Eight machines, one price ceiling, and a lot of spec sheets to read past. That is what went into this roundup of the best TIG welders under 1000 dollars: we worked through every published figure, then weighed each machine against the jobs a garage welder actually has to do. Not the jobs a listing page … Read more
The best TIG welder for beginners is the one that starts cleanly without a scratch-start gamble and hands you heat control without a wall of settings.

Our pick … Read more
