I got this welder from a friend that told me it was not feeding wire, so. I checked all the normal issues and ended up checking the drive wire motor. Thinking it was bad i figured i would hook up a external 12v source to it. Well.... the motor runs fine. but dose not run at all when its hooked up to the welder so im guessing its the ????????????... Any help would be great!
When you pull the trigger does the contactor close and the gas solenoid activate? If not I'd suspect the trigger switch or the wiring in the whip.
If the rest of the systems work when the trigger is pulled I'd work backwards from the motor. Check several settings on the wire speed rheostat, it might have a dead spot there, but it's unlikely.
Thanks for the reply. The gas solinoid clicks just fine, ive went through all the wire speed settings and still nothing... anyone know of a wireing diagram for my welder? Im pretty good with wireing but ive never messed with a welder. Im thinking its either the speed dial or the lil pc board thats bad...i cant seem to find any parts online. I did however notice one of the two wires (neg and pos) that supply the drive motor had a split in the wires insulation so maybe it arked off on something... i dunno...
I down loaded manual for Ironman 210 and it shows TP1 a Thermostat (located on the Rectifier), it is normally closed, opens at 211F, closes at 186F and TP2 Thermostat (located on the Stabilizer, NC. You can see them on the circuit diagram. When the thermostats get higher than set point they open stopping wire feed. You can see location of these thermostats in the circuit diagram showing them switching 24V. As you by pass each thermostat with jumper wire and wire feed starts working then that thermostat is bad needing replaced. CB2 being open could also stop wire feed. Push button to reset.
SR1 Rectifier which looks like a selenium rectifier could also be bad and need replacement. Web search how to test a selenium rectifier. Bad selenium rectifier can be replaced with modern Diodes
Anything beyond this is something on circuit board.
All of these parts are well covered by sheet metal to prevent possible lethal electrical shocks.
You don't seem to know much about electricity so it would be good to find local expert help to find and fix problems with this welder. This could be an electrician or local service center.
