Mig welder

If you are really only going to do the pans, I'd probably work through with what you have. As said, it WILL weld them, just not the prettiest job. I knew I would have a lot more to do on mine so got a Hobart 140. No regrets. Have used it on many other things besides the Duster. If you get a MIG and really don't need it for anything else, it shouldn't be too difficult to sell and recoup most of your money. Or just pay someone to do the pans...
