    OK, I took the skin all the way off and tapped on the contactor, to no avail. It has a button thingee that pops out and in every time the trigger is squeezed, seems to be functioning though I have no point of reference. What's the odds of the gear motor going bad?

    OK Bob, I'm at work and downloaded a parts schematic and see that the contactor is the thing I was calling the solenoid. So the contactor is that thing that is making all the racket. Are you saying that it may be stuck, but it can still make all that racket when it's stuck? I'm gonna unplug it and tap it when I get home, just wanted to be clear on the issue.

    Thanks, Kurt

    I removed the wire and loosen it all up. Should be no tension. I'll try the contactor tomorrow. Thanks again. Kurt

    Is the wire tension open when the gears are trying to turn. Maybe something is binding them up...Bob

    Maybe the contactor is stuck. You will have to take the skin off and its on the backside of where the motor is on the panel housed in a clear plastic cube. Make sure its unplugged first. Then tap on the contactor and plug the machine in without touching a thing and pull the trigger again...Bob

    I pull the trigger and the solenoid (whatever that thing is that makes the noise) fires off but the gears don't move. Are you talking about a circuit breaker inside of the millermatic? Because the machine is on, the noise happens but the gears don't move.

    So you pull the trigger and nothing happens? There is a circuit breaker there someplace make sure its pushed in...Bob

    OK, I was able to take the trigger off and disassemble it. It looks good, the wires both seemed to have good contact. It's getting power from the trigger to the celinoid thing. But the gears just don't turn.

    I guess it could be the plug at the bottom of the handle that has the 2 prongs on it.

    That sounds reasonable Bob. I looked on you-tube for anything related to disasembling a mig handle. Many vids about replacing the liner, but none that I saw about the handle. I looked at the handle and it seems like you can't get it apart. Do I need to get the trigger off first and then go from there.

    Thanks for the advice

    No power control A,b,c,d,e or is it a rheostat type .Try turning it back and forth a bunch of times .Sometimes they get corroded from sitting.

    If I hold it down it feeds forever, if that's what you mean.

    **Update - duh....I was able to pull all of the wire from the cable. When I press the trigger the gears don't even move.
