42v 0.5A socket...whats it for??

[fbc]

On the front of my mig welder i have this socket.

Just curious what it might be for.

control circuit for something what type of welder is it

I would hazard a guess at the feed to an external wire feed

its a britweld multimig. Its an old machine, cant really find much about it.

Wire feed unit or water cooler I should think. I think the cooler on mine is 115V and the wire feed 48V so its more likely a wire feed.

Cheers guys.

Heres what it connects to inside, the two loose wires go to a transformer.

I think 42VAC was used for a heater to prevent the regulator on a pure CO2 cylinder from freezing.

That circuit board has a full-wave bridge and a smoothing cap on it... so that'll be 42V DC then
