Sounds like the wire driver circuit, or drive or motor is faulty. Probably a blow driver transistor or chip. But may be a motor brushes if it has any?

    When I push the trigger I lose my voltage to run the feed motor, the motor works with other power source

    Had the same problem with mine but mine isn't miller and don't know if your's is built the same but if you access the inside of the machine there's there's a large copper spool inside and that wire feed handle is powered through it. The connection heats up over time and becomes a short. I re spliced mine then soldered it and then cut piece of copper tubing and crimped it around the connection and soldered that as well.
    Corrected the problem and I tried pretty much all listed solutions other then this first. Tried the new liner in the torch, the new tip and clamping the wire feed assembly with a clamp instead of the tensioner. All failed. I stumbled on to the fix accidentally when I was trying to install a more heavy duty fan. Hope this helps. Good luck.

    On a 30A air cooled spool gun, why is the wire feed motor not turning?

    What machine is it hooked to. Could be the gun or the machine, or the cable between them.

    Miller spoolmatic pro 30A, It still feeds, but won't arc. Less than a year old, what can I try?

    Run the first layer of wire of the spool you will see a color change. The wire gets a fine layer of oxidation and this causes a bad contact.

    Why wont the wire come through my cosmo gas gasless welder

    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.

    Hello, I would like to purchase 3035 spool gun and attach it to my self made welder. Could somebody to tell me which power supply I have to provide for spool gun motor? DC voltage, amperage ? Can I use...

    the spool gun is a 12volt motor, i usely hook it to the power feed for the feed motor in the welder. it is also 12 volt . i have heard of some welders that have 110 volt feed motors but have not seen one yet but just to be save i would test the power feed to the feed motor before i made the connection.

    I have a 50A spoolgun and wc-24 controll box, but i cain't adjust the heat, and it is way to hot, any ideas as to what the problem may be. it worked fine one day and the next day it was too hot and...

    The control box for the spool gun it's just an adapter to feed the right voltage to the wire feed motor, the heat (voltage) must be adjusted from the three knobs:
    1) Process Contactor knob must be dial on wire feeder CV using remote.
    2) Polarity Must be set on DC
    3) Voltage, depends on thickness of your work piece and wire gage, but 20 volts must be enough for up to 1/4" thickness and 035 4043 aluminum.

    I never heard of a 50A spool gun, probably you meant 30A.

    If your voltage it's erratic check the following:

    Clean and tighten connections both inside and outside unit.

    Check and secure lead connections to remote control.

    Be sure connection to work piece is clean and tight.
    Remove excessive coils from weld cables.

    If continues to be too high (hot) and can't control it, then you should send your machine to be checked that's probably a problem with the PC1 or PC2.

    If this was useful to you please vote. Thank you and good luck.
