I weld on .040" SS a lot so that's not problem. every once and a while I do some .020, not too often.

I'm set on the 200DX, I read about the changes to the new models and that was a wrap. Going to order one up tomorrow from a local sales rep. Slightly less amps then to Precision tig I use a work but equal or better in every other way for half the price. Not too mention I could actually carry up and down stairs by myself.
