I cannot recommend a 220V welder high enough.
truely, if you cheap out and get the 110V unit you will be sorry.
you can find display models on clearance, I did. I paid 450 for my miller 175 INCLUDING a small gas bottle. learned quickly that the small bottle is not worth it. traded it in for the tall gas bottle, have never looked back.
the 175 comes with a cheapo regulator that is fine for learning and light jobs, and it comes with a spool of flux core wire if you don't wanna get the bottle right away.
it comes with the adapter for both size spools of wire, and the whip is ready for a spool gun if you want to weld aluminum someday... (another 450 or so for that gun... never went that way yet, but it's nice to know it's an option.)
my technique has improved over the years, but I would like to take a class someday. I can weld up to 1/2" steel with it (SLOWLY) and down to thin sheet metal with thin wire.
the 110v models will stall constantly on anything over 3/16" unless you REALLY know what you are doing...
