My buddy bought a older snap-on mig/tig MM250sl welder. He said I can use it all I want if I can figure out what's wrong with it. I know pretty much nothing about welder repair. So I need help.
It welds semi consistently at lower settings but once it gets to 5 on the power dial and 5.5 on the wire speed it starts surging real bad and has horrible penetration.
Also the gas keeps flowing whether your welding or not. I found a diagnostic on the web where someone said it's probably the solenoid, they stick when they get dirty.
So I'll be checking that out and trying to clean that.
Any thoughts or suggestions?
