You will have to adjust the tension at the feed wheels, also make sure the spool is not too tight, I had the same trouble with the 180 model, just a bit of fine adjustment

My Hobart 140 will not get hot enough to make a weld. It will feed out the wire, make a spark, and the flux core wire will melt on top of the thin rouaght iron square tube fence but it will not melt into...


Hi:
Sounds like you have the wrong polarity in your machine. If you are using flux core wire, make sure to connect your ground clamp to the positive side and your gun to the negative side. Dial the right voltage and wire speed according to wire size and metal thickness.Let me know if this help.
Regards,D.S.

Newer welders as hobart and miller are set up from factory to use innershield wire therefore polarity is set up as inverse. Check inside your machine and check that ground cable is on negative side. Your gas must be mix argon/CO2 or pure CO2 (not recommended).
Other potential problem is wire not being a mild steel one. Check you have gas flow out of your nozzle.
That's all I can think of.

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.

Weld arc not stable. Wire feeds, good ground,


Arc blow could be the cause! Put your ground on the work piece and weld away from it. If you weld toward a ground clamp the magnetic forces will blow your arc around sometime. When taking a cert this simple mistake can make or break ya on your cap or reinforcement beads.

Weld arc not stable. Wire feeds, good ground, everything looks good, liner pulled and cleaned, new tip.


Try moving the tip closer to your work and try turning your wire speed down
Most people want to crank up the wire speed when it spits and sputters
Turn it down
See if this helps

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.

Northern tool brand wire fed gasless welder feeds wire fan work no welding?


You need to have the ground attached to what you'll be welding on. Make sure there isn't anything on the end of your wire. Also, if your voltage is all the way down it won't do anything either. Oh, one more thing, make sure you have a contact tip on the end inside the cone. That will be the copper thing the wire goes through with a really small hole. I know some of this sounds pretty obvious but if I hadn't done these things at least once.....I wouldn't know what to look at either. I also don't know your experience level and want to cover all avenues. Hope you find it!

Handler 140 wire jerky when welding


make sure rollers are clean and slots not wore out check alignment
do not over tighten wire feed so it smashes the wire
flux wire is hard to get a good setting
make sure if you can set it for gas welding it is not on this setting

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.
