    My machine won't push the wire through any more. Tried replacing the liner which didn't work. Assuming the wire feed motor is faulty is it worth repairing?

    That depends? With deep pockets of cash you might wish to avoid the headache of fixing it and just buy a new one? Or you could do some reading on the subject and decide if it's worth trying to fix the problem?

      You can test motor by disconnecting it from circuit board and putting leads across 12 volt battery... If motor runs, good chance problem may be else where.... Motor is 16 volt DC so 12 volt battery will power it for testing...

      Part #202 708 is going to be tough to find, cursory search does not look to promising for availability...

        Good info. Thanks for taking the time.

          It's almost never the liner. Odd thing to replace before diagnosing the problem. Definitely start with testing the motor with 12V. Do you hear the welder power contactor and gas solenoid clicking when you pull the trigger? These machines have a weak wire connection at the trigger in the gun, also.

          But to answer the other question, it's probably worth replacing a motor if you confirm that is the problem. I replaced the motor in a much older Millermatic 130 ten years ago and it's still going strong, with its original liner.

            Motor part number is
            FET97B47057612A4C11B67C2D842F368D4F. Was less than $30 on Amazon.
            Poor or erratic wire feeding, a loss of amperage or frequent contact tip burnback are all signs of liner problems.
            Also good idea to replace the liner on a machine this old.

              Just a thought, but the wire tension on the reel is not too high, is it? or tangled on the reel?

                Hello, yes tension is good. Problem was the motor. Working fine now! The cost of the motor was very affordable and I was able to replace it myself without any problems. Already completed another project.

                  It's always good to see a good outcome.

                    Hi Paul. So it was the motor. Glad to hear problem solved. Being old, cheap and handy, I have to ask, did you take the motor apart to discover the problem with it? I mention this due to a conversation with a buddy about mechanics.

                    I'm a guy that takes things apart. While not everything ends up back together and running, I've got a pretty good success rate going these days.
                    If you haven't taken that motor apart for a look inside, and I'm no expert, blowing out with compressed air, oiling the spindle bushings and end cup goes a long way to them spinning freely again. Some times the adhesive holding the magnets let loose. No push or pull. Grit and particle could as well disrupt the field I'm guessing but resistance seems to be the killer.

                    The conversation about mechanics...how labour cost was the culprit followed by who knows how. Cheaper to open a box then the effort to take it apart and fix or the experience that's expected to be needed. Then we were on about starter issues, solenoid troubles, worn bushing, grit, grime, crud mixed with a lack of lube usually the issue with starter troubles and failure. But your fixed and running, all good.

                        Hello oldguyfrom56, Voltage at the motor was good so I tried running the motor with the wire tension completely off and gradually increased it. The motor stopped after very little tension was applied. From experience with electric motors this is text book motor problems. For the cost of replacement and the age of the machine there is no reason to attempt to service this type of motor. It is the same motor used in cordless drills which makes it readily available (once you know the part number) and mass produced which helps with the cost. It is very accessible and the polarity is clearly marked on the machine and the replacement motor for easy replacement.

                          Hi Paul, I replied as I did having gone through a similar effort with the same problem. I posted that a while back and while I maybe should have replaced the motor, your points on availability and cost well received, quite justified really, I went the take it apart clean and lube as well the drive gears in the feeder route.
                          Well problem solved, you're feeding wire again, time to weld something.
