Check the current control resistor with an ohm meter. The center terminal should have a smooth rise or fall of resistance when measured to one end or the other of the resistor. If the resistor and the wiring to it are OK, check the shunt in the output it'll be by the "electrode" terminal. If both are OK you probably have a bad control board.

Sounds like your CT or CT board is bad. CT stands for Current Transformer. A CT senses an increase in voltage draw or current, which will trigger the idle solenoid.

Transformer is burned out. Various windings are taken off at different points to alter the amount of power, they have eventually burned right through , So that is why some worked and some didn't It has now completely gone. The cost to replace the transformer may well exceed the cost of a new welder.

check the solenoid make sure its opperating ..you will have to check the whole system.. starting with oil pressure switch making sure it is letting 12v go thrue. and also making sure pc board is grounded . and then checking resistance of the idle solenoid .....also the rhostat has a wire that goes to the pc board and as u strike a arc it idles the welder up
