This machine is supposed to be hooked up to a 20 amp breaker all alone, with nothing else running off that 20 amp breaker. Also are you using an extension cord? It is usually not recommended to do so, although I have the same machine and it seems to do just fine. Just make sure you are getting proper power to the machine.

Check the two main diodes. These units have a light duty cycle. About 20% if I remember correctly. I have one that I was welding with for a considerable amount of time, and burned up the diodes. You can test them by disconnecting the wires (with unit disconnected) and use a ohm meter. You should get a reading in one direction, but not the other. If no reading, then the diode is blown. You can order new ones from your local welding shop. Also check all conections on the secondary for any signs of overheating and loose connections.

Could be a board but it is common for the diodes to overheat and burn out. These welders are only 20% duty cycle. If you do lots of continuous welding it will overheat. If you open the cover and follow the main lead you'll see the two large diodes . See if there are any burnt wires or melted insulation. You can order the diodes from hobart or from your local welding supply. You can test the diodes with an ohm meter. They should conduct in one direction, but not the other. Let us know what you find out!

Auto arc 4110 not working
Check wiring diagram to see if it has a bridge rectifier. My 120 had one and it was bad which would not let the feed motor run. It cost me about $6.00 to replace from Ebay.

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.
Hi I have a Hobart 135 Handler the problem is the
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.

I have a 120 and when that happened to it the bridge rectifier was bad on it. Not sure if your 140 has that or not but just something to look into. It only cost me about 8 or 10 bucks to fix mine.
