  • Hobart 120 pull trigger puts load on unit blows breaker at garage panel

    Like the previous post welding away and just started welding like crap
    fan runs, pulll the trigger unit loads and boggs down then trips breaker at main elec panel
    tested wire feed motor works fine, checked contactor points cleaned works fine, are we still talking about the same problem the diodes or a relay?

    Trouble shooting is making educated guess of what likely caused the problem then test to confirm or eliminate that as your cause.

      breaker

      Sounds like a shorted diode or two. You need a meter with diode test capabilities to check them Read previous post.
      O.F.
