Micro TIG welders

I may have found a source for some 20ga stainless welding coupons, I'll find out next week. I initially asked about carbon steel, but they didn't have any cold rolled steel scraps in that light of a gauge.

If your welder is limited to DC, that might be why you're having issues with aluminum. The AC helps to break up the aluminum oxide layer, so you can get a good weld.

That's one of the big reasons that I bought this TIG welder, it's AC/DC.
