  • Millermatic 200 problem

    I went to use my millermatic 200 today for the first time in about a week, the wire only fed a fraction of an inch and stopped, also it looks like the case is electrified since I got a bit of a shock, even with the power switch off. I couldn't see any evidence of a short yet. Any idea where to start looking?

    is your ground/work cable properly connected to the workpiece??

    do you maybe have a piece of wire caught between the spool and the case?? check the backside..

      I checked the backside and I don't see any wire to case contact, it's all tight to the spool. The ground cable is attached straight to the welding table.

        It looks like my cr1 relay is throwing a fairly long arc when the trigger is pulled any way that could be related?

          Have you taken a case to ground measurement with a meter....??

          to see what potential is on the case.. if it is AC or DC... and what voltage..

          as well as between the case and the legs of the input cable..

              You have 120 off the 230 primary case going to ground. Likely a failed connection in the plug. Won't throw the breaker but it'll wake you up quickly. And the machine doesn't like it much either.
