here's a forum on Hobart welders..hope it helps a little.

Hi:

In order to check the wire speed control you will need to open the machine and test the wire speed control mechanism (rehostat, potentiometer) with the use a volt meter. If you see a a variation on it while moving the knob then your problem is the PC board.

Good luck and have a great day.

Hi:

If you see rust on the wire then you should stop and change the gun's liner, change the contact tip and clean the feed rolls. Rust can accumulate inside the gun and make the wire feeding a problem.

Check ground connection at welder along with your ground clamp. Bad connection could be the issue. Also check settings on your welder.

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

hi,
maybe you haven't got the wire speed control turned up probly not the answer but sometimes its the simply things.

take knob off the restat and turn the reostat if it still goes round n round reostat is shot.

take side panel off where power goes into unit,check for voltage ,if not go to where plug is plugged into check for power if there is power check the crows foot to make sure all three wires are tightly screwed to terminals

check the wiring to the reostat (the resistor that controls the fan speed) also check the reostat has not burnt out. (the reostat should be near the heater motor housing)

please let me know if this helps
cheers

Some welders control wire speed with the amps control, some control amps with the wire speed control. You might try turning things up until it runs smoothly without pushing back. If you're new at welding, it does take some practice until it feels right.
