One other consideration on the 110/220 question. this past week my sister-in-law needed some eyelets welded onto her metal fencepost so that we could connect the barbwire fence to the metal post. The old wooden post next to the metal one had rotted out. We were several hundred yards from any power source. I changed my Lincoln 110 Mig Welder from Mig to Flux and connected it to a 3500 watt generator in the back of my brother-in-law's pickup. Worked like a charm. The Lincoln has also worked well on my trucks and cars from very thin sheetmetal to fairly thick materials. Anything over 1/4" and I'll probably just use a 220V stick welder or oxy/acetylene anyway. Just my $0.02 worth.
