Hello folks,
I own an ancient Clarkeweld 100E that has given me 20 years of reliable service but now has given up the ghost.
Symptoms,
When the relay on the circuit board is held closed I get the familiar 'clunk' from the transformer and touching the welding wire at the end of the torch to the earth clamp gives me eye searing sparks
So that side works.
The switching side in the torch works as I have isolated the circuit and connected up via a 6V motor to a 6V car battery charger.
Depressing the torch trigger causes power to the motor an it runs so that sides ok.
Connecting the the 6V side of my battery charger up to the wire feed motor causes it to run so thats ok
Isolating the 240v/24V transformer on the board and rigging up to mains and then wiring the output side to my trusty 6v motor,
Standing well back and switching on the mains causes the motor to run so the board transformer works
So my deductions thus far narrow it down the the area of the circuit board that operates the relay switching and power to the wire feed motor.
Any idea which components on the board might have blown?
