I bought my MIG welder at Daytona MIG in 1992. Great machine. 140 AMPS at 120V. Did alot of sheetmetal welding. Just have to play around with the settings. I had better luck running a hotter setting and slowing down the wire feed. Gotta run it hot enough to melt the wire. Also, for sheet metal work, only use .023" wire. .030" or .035" is just too thick and will deposit way too much wire (which you'll have to grind off).
I have a 250AMP Airco Heliarc also. That makes 1st class welds on anything, but slow. Definately not for beginners.
