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

Hobart handler 135, the wire starts to feed for about 15 seconds then slows and stops.

Hi:
Don't know how old is your unit but my guess is that your gun's liner is the problem. Have you change it lately? If not, change it. Does your machine just stops feeding the wire or does it shuts down? If it just stop then; is the liner, if it shuts down; then you have a pc board problem.

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.

Hobart handler 135 feed motor for wire doesn't feed wire. motor is ok I tested it with seperate power source. No power to motor from main board or ??????

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 [email protected]

point out what parts to check.and replace.

Hobart Handler 135 not feeding wire

try checking your heat selector switch. the pc board gets power from it. so the pc board relay may function (click) but have little or no power once the curcuit is made to the feed motor. it happened on my 135.

My hobart 135 will not feed wire. I checked for voltage at the drive motor no voltage. The gas still comes on when trigger is pulled but seems that the problem is in the control board?

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.

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.

Seised wire inside feeding tube

You can replace the liner by removing the shroud tip, and pulling the spring (liner) from the machine end of the trifgger cable.
Liners are replaceable.

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.

Sounds simple, but have you checked the spool to ensure that the wire has not crossed over itself. Don't ask me how I know to check this.

Open the cover while you depress the feed trigger and verify if the wire is in the feed-wheel groove and that it's not slipping, that you have good contact and adequate driveroll pressure. It's most likely the switch in the gun trigger, a common failure and cheap to fix to.
