    Handler 120

    Good day guys I've got a Handler 120 that won't work no wire feed and no power to the weld terminals. Fairly new to welding and not sure where to look. I've given once over for loose wires and the like, was working fine thanks for any help guys

    Check for continuity through the trigger wires when trigger is pressed.

    Might check the K2 relay to see if its operating... May indicate problem with transformer or S1 selector switch if not operating...

    Its probably on circuit board and labeled... IF you are not comfortable of how to test relay, maybe it is prudent you don't attempt it...

    Ah, c'mon! You have to tell us where you found the broken wire, and what it went to, and what you think caused it! Do you know how much brainpower we put into thinking about this?! Okay, well, tell us anyway...

    You have to tell us where you found the broken wire, Inside the welder.

    and what it went to, Some other component.

    and what you think caused it! ... Heat and stress caused a malfunction in the electron depletion layer in the outer fibers of the wire.

    Or maybe dragging it around the garage by the gun made something wonky.
