SOURCE: MIG wire is always hot without pulling trigger

Check your manual, there are a lot of mig units on the market that are alway "Live" alternatively, the relay has either shorted or you have wirering problem on the switch.

SOURCE: hobart handler 140 will not feed wire

A schematic would certainly help, give Hobart a call and ask for a wiring diagram. or manual. Hobart are very helpful and may even give you guidance, you may have to pay the postage, they usually fax these documents so it will not cost you anything.

This could be caused by not enough pressure on the drive wheel. Try adjusting pressure as spelled out in you manual.

SOURCE: northern tool mig welder,120 volt with gas.The

This welder is made in China. I have one and it works fine. Parts and service are available from northern tool. 1-800 # is on the book. FYI this 135 gas no gas looks exactly like the Lincoln SP135 and Lincoln workmate 135. GOTO the lincoln site and bring up the manual. It is a free download and is a much better manual than the one it came with. I agree with the previous post. Put a continuity test on the 2 wires that come from the trigger. there is a wire diagram in the book that came with it. Hope this helps.

SOURCE: I have a Hobart 135 Handler wire feed welder that

Get a volt meter, go to ohms setting , check transformer to ground for low to zero ohms reading. also look closely at transformer windings for foreign objects in between them, never know what you my find. If transformer is shorted to ground probably time to say some nice words over it before burial. Also just for kicks try a new gun on it, (there is a reason i'm asking you to do(this) see if you can find someone that has spare. A good honest repair shop would probably be reasonable if all else fails. to a least let you know if the transformers a problem. good luck

I have a craftsman 20511 mig welder it will start welding without pushing trigger


Elmer, If you remove the gun assembly from the machine, if the machine is now not feeding wire, the problem is most likely the gun trigger is faulty. The switch contacts heat up and start sticking over time. If able too disassemble and clean trigger contacts. Check the attached links,instruction and guides, Good luck

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.

I have a hobart 135 handler that with machine plugged in and turned on the wire has constant juice and the gas cylonoid is flowing gas from the bottle without the trigger being pressed. my dealer said it...


Hi:
Have you disconnect the gun's power plug? If the wire and gas stop flowing by doing this action, then your problem is the gun's trigger. If the machine continues to feed gas and wire with the gun disconnected then yes, it is the pc board.
Good luck.

Welder running but wont feed wire etc


Try to short the trigger wire back closer to the unit or better still inside the panel somewhere. There is often a relay that is operated that allows gas to flow and power to the wire feed motor. Check where the trigger wire goes it may give you some idea. If you can identify the part you can source one and see if it worthwile repairing. Cheers
