The welder has triac control but many years ago i purchased a thyristor conversion from a later model. I fitted it but one of the wires came off and blew the circuit board. I checked the gate wire voltage to earth (not sure if that is the correct way to check, it was 240v ac).
I am tempted to buy a new pulse unit to control the thyristor (Semikron skkt27/08e).
My question is are the wire feed and welding diode circuits independant or linked?
Also my existing voltage control circuit has a current trip feedback can i dispense with it?
Thanks for any help.
