W/my EconoTIG, it's near impossible for me to weld sheetmetal. As mentioned earlier in the thread, I think the low end is 20amps. W/my Dynasty 200DX, the low end is 1-5amps I think and it's much easier for a hack like me to not make a complete mess of it.

The specs on Lincoln's site say the low end for the Square Wave 200 is 10amps. I don't think I'd want a low end any higher than that for welding 22GA, but take my comments w/a grain of salt because I'm no expert! When I was looking for a better machine than the EconoTIG, I was zeroing in on machines that had a 5-10amp low end. I lucked out and had a friend getting rid of the 200DX, which is more machine than I need, but it sure is nice to use.

I think in the Square Wave 200 price range, 10amps is as low as the machines go. If you jump up to the next level, the Precision TIG 225 goes down to 5amps.

Hopefully MT930 will comment on if 10amps is low enough...
