You can buy really cheap migs nowadays, they usually come with a roll of flux core thats because they don't have the gauges and you don't have to buy a bottle. I used the flux core wire a long time ago just to use it up before I put gas on the machine and it welded sheetmetal fine, just had more splatter and a white chalky film around the weld. I would not do it now, because I have the right set up. Tell your wife or girlfriend it's your birthday and you need a welder...
The MIG makes it easy and clean. They are so cheap now that every home shop should have one. The stick welder still has a place in a home shop. Do yourself a favor and splurge for a MIG. Donn
i've never done it, or ever seen it done for that matter. if that's all you got then it really don't leave you much choice. probably can be done, but i would'nt even attempt it without practicing on some scraps before you have at it. good luck.
I wouldn't have done it even when I was welding with sticks every day, day after day. I would have used gas when migs weren't commonly available and cheap.
I tried this method several years ago. You can make 1/16" rod work but I'm not sure you'd want to bother.
Learned to gas weld sheet metal. Never did it enough to become really proficient at it but welded in rocker patches and tailpan patches on my old 48 plymouth coupe with good success.
