  • miller 212 no arc

    I have a 212 that is about 3 years old that a friend passed on to me. I have used the unit once about a month ago and all was fine.Today 1) I cannot get an arc when using the standard gun even if I touch the grounding clip direct, but the wire feeds, 2) when I try the same thing with the aluminum gun, it arcs.I know nothing about this. I have checked connections, and voltage to the unit.I tried to "short" across the terminals and got nothing.ANY HELP is appreciated!!

    Basically, it has open circuit voltage, as the aluminum gun works. Can't short the terminals as the unit goes to jog (no OCV) within a few seconds. Sooo, your mig gun is pooched and requires a replacement, or repair. This damaged is caused by yarding the machine around with the gun

      Thank you for the help!
      For future reference, should I not leave the guns plugged into the unit?
      The gun probably doesn't have 15 hours of use.
      Any idea, what repairs might run?

        Don't pull the welder around by the gun... it is not a tow rope..

        You will damage or destroy it...

          See if you can borrow a miller gun to try in it. If it works goo, then you have your answer. The lug is bolted onto the wire feeder portion isnt it?
          If it were mine, I would probably disassemble the gun at both ends and see if I could see the problem. I have shortened a few guns, and it is usually not that hard to get it down to the cablehose.

              Gland nuts squish the cable back on, a bit of a delight if you've never done it before. However, if your in a squeeze for time. I use an aircraft stainless/nickle tye wire as it doesn't work harden. A couple twists and off you go. Problem is finding the tye wire. Can't use the run of the mill home depot crap, as it'll break with a little heat.

                Safety wire is not cheap but readily available from aviation suppliers...

                I kinda favor the MONEL...it does not fatigue, harden or corrode easily..

                  Just getting back to this
                  The only Gland nuts I can find seem to find are called cable gland nuts.
                  So I found safety wire on Ebay

                  http://www.ebay.com/itm/1lb-spool-03...346224&vxp=mtr

                  Would that work?
                  Thanks
