Anyone want to tell me why my wire feed contnues to push out an extra 3-5" of wire after I let off the trigger? I replaced the trigger which helped a bit. It shortened the extra run from about 10" down to the 3-5". I checked around the forum to try and see if this has been discussed but couldn't find it anywhere.

Sounds like the motor relay inside the machine is sticking. You may be able to take it apart and clean the contacts or just replace the relay.

I don't think the contacts can be cleaned on the drive motor relay (Miller Part# 072 817): https://www.amazon.com/Miller-072817-Relay-120Vac-Flange/dp/B004RCDJ14?tag=atomicindus08-20

Seems like you ought to be able to cross that to something generic.

This one doesn’t have the mounting tab molded in but potter brumfield and other manufacturers offer that style for much less coin.
All you need to search is a double pole double throw relay with a 24vac coil based on what PC found as a replacement.

A call to miller tech support with your SN, the tinn off, and a multi meter handy will likely get you the best result.
I have repaired 2 miller relays in my equipment. Fairly easy to crack the covers and fix with a magnifier and small tools, thiugh I don't thnk my hands are steady enough any more.

First thing is to take the cover off and find the relay. 99% sure it will have a model number on it. If you don't have a schematic, turn it on and pull the trigger to see which picks up. Be careful.
