I have a Miller matic wire feeder on a CP-300. The digital read out says "000" when i turn the pot it does nothing. When you pull the trigger it runs at wide open. Can someone help me figure out what is wrong?

Trouble Shoot Millermatic JJ-24 Wire Feeder?

I assume you have a 50 series digital readout model?
With so little to go on, hard to say without more information.
Just shooting at the moon at this point.
If it is a 52/54D series, could be the pot (10 turn 10K), the readout board itself or possibly the tach 'assy & board in the motor casing. If the tach board isn't sending a signal back to the feeder, you have no speed control. Main board could be suspect as well. Lots of things could be the issue.
Post up the model & we'll go from there.So you're telling me...You're not nostalgic? Then, give me another word for it......
