ZX7-200 inverter welder teardown

<< < (4/4)

ealex:
yes, it starts as soon as you power the unit
it's connected across the power supply that powers the control circuit.

acruse60:
Well I must have a faulty unit. have only ran three rods. Fan does not run even when I deliberately worked the welder hard enough to cut out on overtemperature.
Do you have a close up picture of the circuit board connection for the fan?

ealex:
I can't take a picture now, but from this photo:

the fan connector is in the top-right part, left of the mounting screw, the 2 pin connector - you can see one trace on the bottom side going all the way to the auxiliary PSU
