Hello.
I have an Esab Power 250 semi-automatic to be repaired, a cam switch needs to be replaced.
This is a classic 0--10 switch, but it has two additional, non-standard features:
1. Additional contacts (41--40 and 41--42) which are closed in all positions except "zero"...
These contacts are in the motor circuit and the main contactor coil, but their use is pointless in my opinion and could be completely ignore these contacts...
2. In the "ZERO" position, in which there is no welding (because neither the feed motor nor the main contactor is working), the transformer contacts are shorted ... for what purpose?
Regards !
