Well as you know I have a lot of welding to do on the Cobra. I have a 220amp MIG with gas. But it's not the best I've ever used. Sure I'm not a pro at all but I got the privilege to try out an all digital Miller which cost more than my black notch and the difference was simply amazing. I'm wondering if there's something I can get that will allow me to work on sheet metal better. So basically being able to weld 18ga sheet metal up to 12ga structural stuff such as frame rails. I could get a smaller 110v welder for smaller jobs and keep my larger MIG for structural.

I also wanted to learn how to TIG and maybe build a turbo setup (my goal eventually). Not sure if those "all in one" deals are any good...

Any ideas? Keep in mind, I won't be able to spend 5 grand on a welder at this point.

Thanks
