A 110 would probably get you by if you have welding experience. 1/8 wall tubing should work if your design is good. If you are using 1/4 wall, would use a 220 machine. If you are buying a welder, I would pay a little more and get a 220. I built nerf bars for my Bronco with a 140 mig and have held up well. I have a 110,220 and AC/DC stick.
