  • Industrial Craftsman 50/295 Repair

    Hello, I'm replacing the ABC Heat side with some Miller type jack plugs. Concerning the arc jumping inside to the case. Do you guys think the new ⅛" bolts are too close to the lugs?

      Right at ¼" between the grounded bolt and the washer. They are in factory locations but as you can see were a more insulated. I'm sure some of you have done repairs similar, have any issues with current jumping?

        This welder has ocv of 80 or so, takes about 10000 to jump an inch. As long as its not touching its good.

          If you’re worried about it, wouldn’t hurt to put some schmoo over those bolts. It’ll keep it from getting shorted out by a lizard crawling across it at least.

            I appreciate your comments. I could use some self educating on open current voltage. Didn't think about critters getting into the unit. The mud dobbers like building in here when the machine is in Texas. I haven't seen any out here in New Mexico. I found a loose insulator laying on the bottom but I'll be danged if I haven't spotted any witness marks to where it goes. Lend me your eyes if you will.

              Air is an insulator. If they aren't moving around, 1/4" of air is a lot of insulation. As mentioned, welding voltage is relatively low.
