Welder running but wont feed wire etc

A lot of wire feeding problems can be cured by changing the contact tip. It only takes a little contamination, weld splatter, arcing to cause the symptoms you've described.
With over 40 years experience with wire feed welder I've
found that 9 out of ten times feeding problems are tip related. The drive roll tension cab sometimes cause the symptoms you're describing. Also keeping your mig torch as straight as possible, no curls or bends will help eliminate feeding issues.

I would call miller and get a number for the closest repair station. They have a three year parts and labor warranty. 1-920-735-4505

Most mig welders have reversible feed spools. There is a good chance you have the spool in the .030 wire side. Remove the spool retaining clip and flip the spool to .023 wire for example. I don't know what size wire you are using. Also there is an adjustment for the drive spool. Tighten the tensioner spring thumb screw to increase the feed tension.

First thing I would check is the relay that sends power to the transformer when you pull the trigger. That can be one of the hardest parts of a Mig welder to troubleshoot because you can read full voltage through the thing with a multimeter when the contacts are dirty and it's not functioning properly.

That's assuming you're losing power. If it's a feed issue then we can address that later.

Hi I have the same welder with the same problem, I've striped it down and found that there are a few teeth missing on the gears that run the wire feed,
Had no luck finding any replacement parts though

if you mean from flux core wire to gas shielded wire you will need a tank and regulators,and feed hose from the welder to the tank

Change the contact tip.This is the most common problem. The tip gets burned and keeps the wire from feeding. You should always have extra tips on hand.

i had the same problem. its probably a bad solder on the wire feed pot. not hard to fix ,but you need a solering iron .BE CAREFULL 1 unplug welder.
2 remove pot and the nut underneath.
3 remove case from welder and remove controll box.
4 run the soldering iron over the joins , then put it all back together, should work fine.

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.
