    Default Problem running a miller s-22a wire feeder with shopmaster 300

    Hey guys, new to the forums here, I've got an issue I hope you guys can help me solve.. I picked up a shopmaster 300 off Craigslist the other day, it came with a high frequency tig box, spool gun and a wire feeder. When I went to look at the welder, we started it up and I ran a few tig beads, then we went to switch it to mig, and when I would pull the trigger on the mig gun nothing happens. the shopmaster would make a small noise for about 3-4 seconds, and then the noise stops. We opened up the wire feeder, and the feeder wheels will twitch just slighty every time I pull the trigger. The guy I bought the machine from didn't really know a thing about it, he bought it a few months ago and never even used it. He did tell me that when he went to buy it from the previous owner the mig was working. Honestly it could be simple as something not being hooked up right, or a switch or something like that. I'm not familiar with this machine and I couldn't find hardly anything online. Anybody have any ideas what to look for or where to start?

    Go into the resources tab and download an owners manual for it to check your set up. The techs here are much more friendly when you post up serial/model numbers of both your pieces of equipment. Pictures of how it is wired up would help a lot too.

    Duh, have to read the question,,,, thinking Synchrowave. Yes the 22A will be fine on the shop master. Toooo hot here , can't think. Apparently can't read either.

    You have a trigger to conduit issue, ie, failed gun. Problem is usually in the gun head itself.

    Sorry it took so long for me to reply, I've been out of town for work.
    The serial number is KE615783

    I shot a video of the problem hoping it might give you a better idea. Here's the link

    Remove the trigger connection from the feeder and take a piece of mig wire and jumper the trigger terminals at the feeder, to determine whether or not, the problem is with the gun or with the feeder. Opening the shopmaster is a little premature as the feeder feeds wire, which has ZERO to do with the shopmaster operation. Unsure why people do this.

    Right, it's a new machine to me so I was just checking for anything obviously out of wack. I'll try the jumper thing tomorrow morning and let you know. Thanks for the tips I appreciate it

    OK, I jumpered the trigger wires like you suggested, no luck. It does the exact same thing. I hear a click, the drive rolls twitch like they are starting to spin, then a buzzing sound from the shopmaster for 3-4 seconds. Also, it does the same thing when I hit the "jog" switch on the wire feeder.

    I disconnected the wires to the motor, tested them with a meter, they are at around 26 volts.

    I hooked up the drive motor to a battery, and it operates just as it should. I'm really stumped now.

    What else should I check?

    Make sure that the feeder's control cable connector is wiggled all the way into the shopmaster. If so , then remove it and make sure you have 24VAC between "A" and "G" on the shopmaster amphenol. Metering out and running the feeder motor tells us ZERO
