Miller 130XP won't feed wire

Usually, the drive motor voltage is derived from the weld voltage, so if you lose, the weld voltage, the motor will not turn. Feed some wire out in a setting that works, then switch to one that doesn't feed, and see if the wire will arc. If you have a voltmeter, check for DC voltage at the polarity changover. Might be a bad voltage range switch.

you may have a bad fan motor that needs replacing. if you unplug the cooling fan and direct feed the motor with jumper wires and it doesn`t run then the fan motor needs replacing. this is what it sounds like as it should run when the motor gets to a certain temp or the a/c is turned on.

Just a thought, have you tried feeding the wire manually to see if there aren't any obstruction through to the handle or nozzle? Hope this helps

I use mostly .23 wire and keep the co2 between 10-12, smaller wire less gas

A good test method is buy a rco-410 hard start relay. Once you have it, cut an old plug off something and leaving the plug intact, splice the two wires at the cut end with the two wires on thet really that don't have metal ends. Once that is done securly, unplug the fridgem take the really off the compressor and hook up the home made compressor tester. Once plugged in if the compressor is good it will come on, it it doesn't it's bad. This works becuase you remove any variables that are present with the machine hooked up normal.

Have a 130 xp welds the same with or with out the gas welds not smooth

It's called the fire feed wheel. They sometimes come in sets but, running .035, you probably have one grooved and one flat. Any welding supply that handles Miller welders should have them or be able to get them.

Give the whole welder a good cleaning and then look for a short to ground.

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

i have a mastercraft welder wire feed , the power turns on the wire feed works and the fan in side turns on but it will not weld not even a spark! can anyone help?
