My recommendation is first of all, buy "quality". If you are truely serious about your car and the build, then you should not even be looking at Harbor Freight or similar welders, IMHO. I have a 175amp Mig, a 180amp Tig, and plasma cutter, all by Miller and all are 220V. I feel your first welder should be a Mig, you'd get the most use out of the Mig in general welding, as it's very easy to learn and does a nice job. If after, you need to get a Tig welder, first go to a J.C. and take a Tig class and learn the right way.
Also, years from now, if you ever decide to sell your welder, you will recoup more of your money back than if you had a Brand X welder.
