Welders?

I've got a 110 vac Hobart 140 mig welder. I use it mostly with flux core wire, for welding 18 and 16 ga. cold rolled steel, and it does a great job. With argon I weld aluminum's and heavier gauges of cold rolled, hot rolled, and galvanized steel .

I've used it on everything up to 5/16" thick mild steel, and it's worked fine.
