20 Most Recent Campbell Hausfeld MIG / Flux Core Wire Feed Welder Questions & Answers

Overheating can cause damage to the internal components of a welder, including the wire feed motor, transformer, and electronic components. It's possible that the high setting on your Campbell Hausfeld WF2050 welder has been damaged due to the overheating. You may need to check the high setting circuitry to see if there are any visible signs of damage, such as melted wires or burnt components. If you're not familiar with electrical components, it may be best to have a qualified technician or electrician check the welder for you. Alternatively, it's also possible that the wire feed motor may have been damaged during the overheating. A damaged wire feed motor can cause the wire to feed improperly, which can affect the quality of the weld. You may need to check the wire feed motor to see if it's functioning properly. In any case, it's important to address the overheating issue to prevent further damage to your welder. Make sure that the welder is being used in a well-ventilated area and that the cooling fan is working properly. Additionally, make sure that the welder is not being overloaded by using the appropriate amperage setting for the job.

You should have one contactor for the wire feed. And the tip should be hot all of the time. Trace the connections. The conductive strap from the gun whould go to one side of the main transformer secondary winding- usually to the current selector center contact. If you disregard the diodes for a moment- the circuit completes through the ground lead. Somewhere, and it may be where the gun assembly attaches to the feed mechanism that the whole unit is shorting out- Is part of the cable from the assembly contacting the cabinet? Did you remove the feed assembly and were there insulating washers present? One of those may be knicked. Did a screw of the wrong length get put in?The rectifiers can go into the circuit either way depending how you want it polarized- or omitted even to weld AC. Normally the rectifiers would go on the supply side, and not the ground- so it would be located betwee the current/heat switch and the strap that goes to the gun. Unless you put the insulting hardware on to islate the rectifiers from the heat sink. That heat sink is likely live that the rectifiers are mounted on, and as a result, you are shorting out the transformer. You can either iloate the heat sink with phenolic board and plasticscrews and nuts to attach to frame Or get the isolating hardware and iaolate the rectifers from the heat sink.The grounding cable is the only thing that should be a metal to metal contact with the frame of the welder.

Hi:
Disconnect you ground clamp form the negative side pole and switch it to the positive pole, same for the gun disconnect the from the positive side and switch it to the negative pole.
Good luck.

it will be in torch, fix suitable torch
