Have a 110 volt mig wire feed. motor slows to a

Hi,
To get parts for your welder you'll need to have the serial number off the tag on the case. This problem could have other causes, have you:
Checked the tension on the wire spool? You ought to be able to pull the wire by hand easily.
Checked the tension setting on the pinch rollers? Too much tension can drag down the motor speed.

You could also have a bad control card depending on which model wire feeder this is.

Regards,
Carl

Hi Stan, the best thing to do is phone Hobart or the hobart agent for a price on a new motor, however this sounds like it is a power transistor over heating in the circuit, these power transistors are mounted on a large "fined" aluminum plate, take a look for signs of heat around the transistor mounting or have a decent electrician to test them, referring back to Hobart, these guy's provide good service, they have a help line also but I don't have the number.
lets know how thing work out
