Check out http://www.lincoln.com I have the Lincoln SP125 it's a Mig welder (wire feed) and runs on 110v. It also can be used with or without gas. I only use gas as it welds with less splatter, and cleaner welds by far. I use C25 which is 75% Co2 and 25% Argon which welds steel, Iron very good! I had a rusted out driver side frame rail. I have blue prints someplace around here for it, but you will need one for the other side. My prints that I made are for what is called a "Doubler" frame. Its an exact fit frame that slips over the old one, then you weld it together. Mine worked real good. I work on aircraft and we have to build these doubler frames all the time, thats where I learned to build them and I know they are as strong or even stronger than the factory one. They are easy to make, just strip everything off the frame (suspension, struts, bolts and stuff) measure it all, build it, slip it on and weld it together. I also built a new drivers side strut tower as that was also rusted out. I cut what was left of the old one off, and welded the new one in. This was on my 1974 260Z. Hope this helps. madmike...
