    I think you need to take the cover off and check does the fan constantly run normally? or does it kick in when it warms up?

    might be that it has simply dies then should be a easy swap if it has

    take cover off, switch on, check voltage feed to the fan? It's basic diagnosis, you don't need the internet to tell you that.

    Probably a 24v fan mate, should be easy enough to check with the meter...

    Bump: need an owners manual for one of these in PDF format if anyone has one? Need the pinouts for the remote 14 and remote 17 sockets to make up some interconnects.

    The Victor website links are all broken/go straight to the esab na website nowadays :(
