I'm new to the forum so hello!
I own an old Sealey Supermig 180/5 and I recently decided to covert it to a euro torch. It has all gone well apart from installing the gas solenoid.
Its a 240volt version and I know where it is supposed to hook up to on the output of the power solenoid, but it is not working as it's not getting power when I press the trigger.
I've tested the power solenoid, and it clicks when the trigger is pressed plus the welding torch arcs to the earth clamp as it should. I've also removed the connectors from the power solenoid to test continuity and it opens and closes with the trigger correctly, but with just the COM side connected, the NO output side disconnected and the trigger not pressed I get 240volts at the NO output side.
Also when I meter it with both connecters in place something also seems wrong; without the trigger pressed at the COM side the power coming in is 240volts and zero volts at NO, which seems correct, but when I press the trigger instead of getting 240volts at the NO output side I only get about 16 millivolts, which doesn't make sense as the torch still arcs to the earth clamp.
It's been driving me mad anybody offer any help or insight into what may be going on here? I've attached an image of the PCB if it helps.
Cheers
