SOURCE: CP 302 wlder

Trigger the wirefeeder while listening for the contactor on the CP302 to close, if it does start looking for loose, bad or missing ground connections to the work, then look for the power connection from the CP302 to the wirefeeder to be bad. If the CP302 contactor doesn't close look at the control cable between the wirefeeder and the CP302, try a different one if possible. If you hear the contactor close, and everything else is good, check the voltage at the CP302 output terminals to see if you may have a bad contactor.

SOURCE: WIRE FEED BUT NO ARC

Turn off welder, unplug and press trigger to discharge any possible stored juice. Then, open side door and check the ground cable where it connects inside, it sounds like either ground or the hot is off. Once you determine those are both securely attached, close door, plug in power on, attach ground clamp to test piece off metal and try it again. Let me know if this helps! Thanks:)

SOURCE: No arc/ no burn

You need to inspect the ground.Where it connects to the machine, and at the end. I bet one of the connections or the wire itself is damaged.

SOURCE: Wire won't feed into hose adapter.

You will have to adjust the tension at the feed wheels, also make sure the spool is not too tight, I had the same trouble with the 180 model, just a bit of fine adjustment

Miller 130 wire advances, fan runs, but will not arc as wire comes out


Most of these machines (would have to have serial number to be sure) will not feed if their is no output voltage, since part of the motor voltage comes from the arc voltage.
So, I would suspect broken wires, either in the work lead or the gun. If it arcs just a little, probably the gun. One place the work lead breaks is right at the back of the clamp. Pull on the insulation and see if it "stretches". If so, the wire there is broken.

Murex transmig 405s


The contactor that controls the power to the tip (the heavy one) may be fused closed This interupts power to the primary winding if tip goes live without wire feeding.
. It may also be a shorted SCR on the control board if wire is feeding or it can also be a fused feed motor contactor- the small one.

Weld arc not stable. Wire feeds, good ground,


Arc blow could be the cause! Put your ground on the work piece and weld away from it. If you weld toward a ground clamp the magnetic forces will blow your arc around sometime. When taking a cert this simple mistake can make or break ya on your cap or reinforcement beads.

My Hobart 175 Handler wire feed stops shortly after the arc is struck. Recovers in about 20 seconds. Motor protection ckt is probably doing it. No restriction in feed cable or gun, wire moves smoothly....


Yes sounds like it is "Detecting" a "Fault" condition and shutting down the Arc for safety, then it recovers, and it repeats, I think, you should Check, your Earth leads, Connections, and Overcurrent Protection Threshold if there is a control. Check power is going to the feed motor at time of arc, and if it is still getting enough or if it, the voltage to it,"Sags" under load...In this case it is a power supply problem.

Wire won't feed or arc fan runns


Look for a reset button on the case. Make sure that you have power to the machine and at the power socket. If everything looks ok outside, you may have to investigate your warranty. Good luck!

Hi, I have a murex tradesmig 160, when welding its like it loses its earth, but earth ok, some times get a good run, and then wont work. feeds wire but no power.


Look inside the unit (make sure the set is unpluged from the wall socket) and check the bolt that secures the cable to the socket, remove the bolt and clean the earth lead and the socket, check that the cable is ok and tight when refastend.
