The 220 is a Lincoln 180 PRO, even on the lowest set, with the gas pressure turned down to about 8 psi, it blows thru even on tack welds. Even with .024 wire, the thinnest the machine can handle. It’s useable but figured for 100 bucks, I’ll try this one and see if that helps. If not, oh well. I’ll put it in the tool trailer I’m building for field repairs.
