Max Arc Ltd MIG300 - wiring issue

[JGC Engineering]

I recently acquired a Max Arc MIG300 welder at an auction, unfortunately the mains power cable has been removed and I can’t find a wiring diagram to connect a new one.

See attached pictures, it’s a three phase machine with a single phase cooling fan. 3 phases, earth but no neutral.

Anybody able to point me in the right direction of getting this machine wired up again?

Thanks in advance.

I previously posted this in the welders and welding machines section but got no response so I’m reposting here in the hope someone can help!

Would it be possible to get a picture of the terminals in the picture below



Did you disconnect the two wires?

Don't worry about the fan being single phase in a three phase machine. If the machine has a phase swapped when connected the cooling fan will always run in the correct direction.

Sorry for the slow reply, see attached pictures. There are two glass type fuses in the rear.

The two wires were already disconnected and tucked underneath the white Arrow Hart contractor.

Without a wiring diagram for me the first place to start looking would be to check what is connected to these four connections. Before connecting any voltage to it try to make your own diagram of the basic wiring
