FWIW I did use my buddy's fancy Miller at his body shop a bit to do some panel patching, and for that kind of work, I didn't really find his did any better of a job than mine.
But when it comes to welding thicker stuff, will yours do as good of a job as his ???? Nobody is denying the ability of a 110v welder to do sheet metal, they just lack the balls to do heavy stuff which limits their versatility. But as is typical of this site, someone's going to say they've welded 1/2" plate with one !!
