i wouldnt buy a 220 welder if your just getting into welding. i would get a good 110v hobart or something similar. b/c if you really get into the welding thing, you could sell the welder and upgrade, and not loose too much money from the initial price. but if ya start out with a 220v thats a bigger investment and if its not your thing, you will loose a greater amount of money on the resale...
and being able to plug the welder in to any outlet(provided fuse in the breaker doesnt blow) will be a plus in my eyes b/c you could pack it up and go to a buddys house and do welding there without the hassle of finding a 220 outlet..
i had a truck.
