Make sure the trigger switch is applying power to the motor. If there is no reading when you checked for OHMS then the motor is open. You'll have to get a new one.

SOURCE: hobart handler 135 wire feeds for about a two feet

This happens to me all the time. Wear and tear has taken its toll and everything has to be maintained for it to work. Most likely the welding tip is worn and should be replaced. Lincoln electric tips work well and I will replace mine several times during the day. Also check your tension and make sure the wire will uncoil freely from the spool. You can remove the tip and make sure the wire will feed without it. If not, your liner may be worn out. Also a welding Jell will help keep the tip from cloging. It will still happen, but hopefully not on your first weld of the day.

Wire feed is not stable on Hobart handler 135


is this a lower end machine ? the cheaper machines take the power from the welding transformer to power the feed motor and as a result the feed isn't stable, also is the wire liner and tip in good condition if not replace them, try blowing through the liner with compressed air to clear any dust from the wire

Hi I have a Hobart 135 Handler the problem is the feed motor only works for a few minutes of welding and then slows down or stops the goes slow again.


First there is a overload for the drive motor incase the welding wire gets jammed. I've had one of these for a number of years and only recently understood the markings on the drive wheels. When the wheel is installed, the markings for the wire size is for the wire you're using. In other words, the marking is towards you but is indicating the size for the rear groove. For years, I looked at the numbers and assumed that they were for the groove closest to the numbers. I had no problem with solid wire, but with flux core all kinds of trouble. So, make sure you have the right groove for the wire size. Second make sure there are no kinks in your hose. Make sure your contact tips in the gun are the right size for your wire and in good condition A person has e a tendacy to make ther drive wheels tighter when the feed slips, this can cause problems for the flux core wire if the correct drive wheel is not selected.

I have a hobart handler 135 motor stops feeding


Take the drive motor off and blow out dust, chips, wire pieces, etc. and then rinse out with contact cleaner, blow dry, re-install. Had to do this every so often with mine. Hope that helps.

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.

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.

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.
