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.

Check the selector switch with an ohm meter. Unplug the unit, ground to chassis and probe the contacts while turning the switch on and off.

The gas won't shut off once I release the trigger, sometimes the wire continues as well.


Hi:The solenoid valve gets the current once the switch is activated (pressed) therefore my opinion is that you have a sticky trigger. or one of the terminals of the cables it's shorting out.Change the trigger or better yet check that the terminals are clear and not touching other parts of the handle.

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.

Hobart 140 voltage drop when welding in all setting using 30 wire and uni mix gas will start out welding good then will not ?????


Check your input line voltage. 115 volt Mig welders / plasma cutters need stable voltage / current. Test to see if the voltage drops to below 100 volts when welding. If so, find a more stable power supply.

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.

Wire feeds too quickly


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.
