I have a cheap 110v Harbor freight wire feed welder. I know it's not a very good welder but I don't use it very often. Does anybody know if I might be able to convert that to a full MIG welder? I seem to remember seeing a kit for that a long time ago when I bought the welder, but now I can't find anything about it on their website. It does say "Easy MIG" on the front of the welder, it's not really MIG unless it can use gas, right?
