I've got a miller 185 mig welder. I've never had much luck with it on sheet metal but I've seen welds others have done that look good. I have trouble seeing where to strike for starters then things just get too hot too fast. I used to do a lot of gas welding but can't seem to get that flow with the Mig. I've been considering looking for a Tig setup to do some sheet work. Any suggestions?
