Snap On MW120 MIG Welder

I don't disagree, but once again, it's welded decent with .035 wire and that's what it HAS NOW. DO YOU UNDERSTAND THAT? I've tried the .023 off my Craftsman machine and it did the exact same thing, so I put that wire back on the Craftsman since I am doing exhaust work on my truck. It's not the wire size, ok? I appreciate all the input, but arguing over the wire size is a moot point since that's not the issue.
Yes, I understand the wire size is not the problem at hand, It sounds as if there’s some electrical issue inside to be diagnosed. Toplscuda sounds as if he has the skills to guide you through diagnosing that issue. Hopefully you can get it going again.
