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.

SOURCE: I have a hobart handler 120/90amp wire feed welder

I have welded countless hours with Linde & Lincoln & even a few Hobarts & the only time that I ever had the same problem was when the ground connection either to the object I was welding, or the welding cable ground wasn't good & clean & tight. Same on stick welders also. I did develop the habit of grinding not only where I was preparing to weld, but where I was placing my ground clamp & that always provided a better "frying bacon" sound as I went along the business of pushing a bead. In a welder, the only other thing than that is involved is the step-up transformer and your wire. Hope this helps.

First take our the spool of wire, then without any wire restriction, disconnect the gun from the machine and bridge the trigger connection, if the solenoid valve opens then the motor shoulod run. If it does, then check the trigger on your gun, take it off and bridge the cables, if it runs then your trigger switch is faulty.

Hi there,
I found a manual that has a lot of information in it.These welders only have a duty cycle of 30% so that means you can only run them 3 minutes out of 10.They have thermo switches that shut them down before they get to hot.The house breaker needs to be around 50 amps at least I have a 125 buzz box and a wire feed and that's what I use.I would check the circuit breaker in the house to see if its tripped.I turn my mig on the side so that the shavings from the wire pushing wheels don't get pushed into the liner and clog the wire and make it jam.Well hope this helps.Thank You for choosing FixYa.com and good luck!

My Hobart Handler 120 stopped working during a welding process. Now when I pull the trigger, the 30a 110v circuit breaker trips. The machine can be turned on and the breaker holds (cooling fan in the...


Please don't give me a bad rating for this. Its just a little extra info. you didn't mention that may help you find the problem. Depending on your specific model, there should be 1 or 2 breakers on the unit it self. If there is only 1, it will shut down the entire machine when tripped. If there are 2, the top one is for the whole unit and the lower one is for the wire feeder motor only. There is also a thermal overload that will shut down everything except the cooling fan. Secure the trigger closed and let the fan run for a while to see if it re-starts when cooled. If the depth of the weld was stable before the problem occurred, I would suspect a short in the motor and not the rectifier. That is not a sure bet though. If the transformer does not start when it cools, UNPLUG the welder and short the transformer to ground to be sure the capacitor is discharged. Then isolate the feed motor and transformer and use an OHM meter to test them individually to ground for a short. With a little luck, it will be the feed motor. Please let me know if this helped at all. I am new and still learning how to explain what I am thinking. Thanks for writing us.

Have Hobart 140 Handler, The motor won't run to feed the wire, even whith out wire. gas will come on when trigger depressed.Where can I find parts to fix?


You need to look at the wiring diagram to see what parts could be causing the problem. I had a 120 that did the same thing and it was the bridge rectifier that was bad. I unhooked my motor and hooked it to my battery charger to see if it was good.Hope this helps. I will see if I can find a diagram to look at and check back later to see if you have fixed the problem.

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
