I completely agree with everything you said, except for the part about me insisting on 220V. All I'm saying is it's a better machine. I started out with a 120V machine that drew 30 amps, and it would pop breakers left and right whenever I taxed its limitations. The bigger 120 V machines, Millers and Hobart’s, have taps which allow you to run on 120 or 220V. I now am the proud owner of a Millermatic 210, with the spool gun, MIG torch and plasma cutter attachments, with the 3 gas bottle setup. I can weld aluminum, steel and stainless, the only set up required to go from one to the other is turning on the gas and changing the spool (for stainless), but I use mine to make a living. You make an excellent point that has not yet been expanded upon. Before you buy anything, make sure your electrical supply can handle it. Look in the breaker box and check to see if you have the capacity to run the machine you are considering. If you don't know what you’re looking at in the breaker box, find someone that does, and get the most powerful machine you can support.
