Hi, sometimes the wire gets stuck when feeding through at the copper welding electrode tip piece.. Try unscrewing the welding tip on the welding hand piece to make sure the wire is not getting stuck there. If the wire come through with the tip removed, then screw the tip back on over the wire. See if the wire will feed through a meter or two untill it hits the welding tip.

If your welder is less than 3 years old your local Miller authorized service center will repair it for FREE. They can also check the serial number of your welder over the phone to see if it is still in warranty. For goodness sake DON'T tell them you've been mucking around inside the welder or they won't be able to help you.
That said, if the welder spins the feed wheels without any wire between them it probably isn't the board. There is the switch in the gun, the board, and the motor and brake assembly all needed to feed the wire.

A schematic would certainly help, give Hobart a call and ask for a wiring diagram. or manual. Hobart are very helpful and may even give you guidance, you may have to pay the postage, they usually fax these documents so it will not cost you anything.

Hi there,
If the knob spins all the way around (and especially of it didn't always do that), it's broken. This could mean that the nut that holds the rheostat in place has come loose, or it could be that the wiper inside the rheostat has broken off the shaft. To find the voltage measurements, correct schematics, etc, I'd need to know the serial number of your welder.
Regards,
Carl
SOURCE: Wire does not feed on MIG welder
my lincoln mig welder did the same exact thing!! I thought what you did, drive motor bad. But it wasn't, on mine there is a reset/breaker button, it's like a 25 amp fuse that can be reset, it was bad! so I took the 2 wires that went in and out of it and jumped them together (not advised) to see if it would work then. BINGO!! now I have to find replacement. Look inside for a fuse or some thing like that.
hope this helps, oh yeah, when I ask the mechanic at the welding store he said that drive motors rarely go bad!!

does it have a reset button? if so it has gone bad, if not there is a fuse or something inside. they protect that circuit against shorting at the working end of the gun. happens ALL the time.
