Question about Hobart Welder, Dctig And Flux Cored Wire Feed, Champion 10,000 With Kohler 20 Hp Ohv Engine

Open Question

My used Hobart 175 had a nagging wire feed problem and then just stopped feeding. The motor does not spin when trigger is closed. I checked motor windings with 2.5 ohms resulting. I checked voltage at motor with trigger closed = 0.1 VDC. Checked connection at the PCB and powered up. Sounds like relay is working bt no motor movement. Can you suggest further troubleshooting or tell me if this is a common problem with best fix?

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: My hobart 135 will not feed wire.

does it have a reset button? if so it has gone bad, if not there is a fuse or something inside. they protect that circuit against shorting at the working end of the gun. happens ALL the time.

SOURCE: Hobart Handler 175 Wire doesn't feed when trigger operated.

First, UNPLUG the Welder! There is a small control board (2"x2") that the feed motor plugs into, it has a fuse on it. Here is what you do: Follow the circuit board trace that goes from one side of the fuse though a resistor then to the connector full of wires on the edge of the board, check that resistor for continuity it should read some value besides open. If it is open, this is your problem (as the drive motor ages it draws slightly more current than new, which should blow fuse, but instead blows the resistor). The resistor should be replaced with same resistance value, if problem persists replace again but instead of 1/4amp bump up to a 3/4amp for $1 or replace that drive motor for $150, you choose. Good Luck!

NOTE: As with any circuit board, take precautions to prevent ESD damage to board.

SOURCE: hobart 135 wire feed sped control problem

you have a resistor down, first check the resistor on the centre pole then those going off to the two other pins

SOURCE: hobart handler 135 feed motor for wire doesn't

check the SCR ,looks like a big transistor mounted
to a heat sink or some of the older units had a relay
in-line with a fuse , I have a older Hobart and it is
a great little welder. If you snap a pic of the P.C.
board and email it ill rsheehan@northernsteeldesigns.com

point out what parts to check.and replace.

I have a hobart Handler 135 and it won't feed the wire correctly. At first it will feed about 6 " of wire then it goes down to about an inch at a time then it will just click. If you wait awhile it will...


If you completely remove wire from unit does it still slowdown and stop when you pull trigger?
If yes, then 2 most common problems are
A. Thermistor @ position PTC1 on circuit board
B. Drive Roller Motor

To diagnose, locate thermistor @ position PTC1 in upper middle part of circuit board.
It's yellowish round and about 1/2" in diameter.
Jumper Accross the 2 leads, use a small insulated screwdriver or meter probe.


1. Pull trigger on gun, when motor slows or stops then jumper the leads, if it speeds back up then it's the Thermistor
Replace with a Raychem RXE 1.85A @ 72 v
Or comparable, try EBay

2. If no change, isolate motor by removing the 2 leads and connect a 9-12 volt DC battery source, does motor spin? If not then motor is problem. If motor spins and is constant then additional troubleshooting needed, next possible issues are bad resistor or scr

Lincon mig stops feeding wire


Been welding for a while, open side, check for proper tension on the feed wheel inside side panel, hit the trigger, if feed motor continues to spin tensioner needs tightened or mig wire may be getting hung up inside main cable lead. If motor is off on off on then its probbably the switch on the trigger getting a bad good connection, hope this helps o and check welding tip on gun end, may need replaced if worn or melted, unscrews.

Hello, I have a Hobart 180 and the wire feeder motor won't run. I replaced the wire feed motor and it still won't run. any ideas?


Sound like you have a bad trigger on the gun. Does gas spray when you pull the trigger? Check the wire plug that goes from the pistol to the unit. It should be under the liner hose where it connects to the machine. Then use a voltage meter on the wires going to the drive feed motor, and see if you get current when you pull the trigger. If gas doesn't spray neither, sounds like you got a bad trigger switch

My hobart handler 120 will not feed wire. took the feed motor off and tested. Its good. checked the trigger connections and they are both in good shape. The gas valve does click when the trigger is pulled....


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.

Miller 175 trigger will not feed wire very


First thing make sure the lead cable is as straight as possible. and make sure the wire has a unobstructed path. then you should check the trigger input/output switch and see if the switch is getting power to it continuously. I hope this help please rate this thank you

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.

I have a hobart handler 135


You do not indicate if the wire is already out of the nozzle. If not, commonly the wire can jab the side of the tube it runs through and cannot advance.

IF the wire is already threaded, then there MAY be a fuse to protect the motor.

The click MAY be the gas valve, or the relay driving the motor and/or the main transformer for welding current. The circuitry for these is relatively simple and a voltmeter is your friend to troubleshoot this.

Relay clicks, but wire feed motor wont operate


check for power to drive motor,if power is there when you pull gun trigger then motor is bad.if no power look for bad wire connections then relay.
