I'm trying to figure out why my m252 keeps messing up on me. Quite often the lead and gun will start vibrating really bad. Then the wire starts spitting out until it just quits on me. I'll check to make sure the lead is fairly strait and that the tip is clean. Everything will check out and I'll jog the wire. It will feed just fine. Then as soon as I stile an arc it messes up again. The liner is new and I've tried just about everything I can think of to fix it. I know it not meant for heavy industrial use but my bosses seem to think that it is. Could these symptoms be from over use or is this welder just junk?
