I've narrowed down my coices to one of three mig welders. It'll either be the Lincoln Weldpak 155 or the Weldpak 100 at Home Depot, or the Craftsman mig welder at Sears. The Weldpak 155 is a 220 volt machine but that's no problem, I can plug it into my dryer outlet. The Weldpak 100 and the Craftsman machines are 110 volt. (didn't check duty cycles) I'd like to solicit some opinions from you guys. Which would be better, The machine with a 220 volt or 110 volt input? The Lincoln machines would require the additional purchase of the mig conversion kit, but I'm really interested in hearing opinions on the 220/110 volt pros and cons. That's pretty much what I'm trying to decide. Thanks guys.
