Motamig 185 wiring diagram

[classic2cv]

Hi there I've just bought a Motamig 185 from an auction, I plugged it in and found that the contactor just drops down and stays there until switched off
Does anyone know much about these or have a wiring diagram for it?

It looks like a nice machine

Have a look at the PCB to see if there's any visually faulty components. It could also be worth testing the contactor by bypassing the PCB. There's probably a small transformer that supplies the PCB and probably the same voltage as the contactor.

Explain a bit more.
Does the contractor get pulled in on switch on if so first try and see if it does the same without the gun connected to euro connector

Hi
It happens when I pull the trigger on the torch, the contactor drops down but does not come up when I release it, and only comes up once I've turned it off

i,ve tried the welder but the wire drive is not working, i'll check for power but it would be nice to have a wiring diagram, so i can trace the power

The picture appears to show that the Mode switch is set to Spot welding.
If it is in that position, the contactor should still release after a timed delay, but maybe the timer circuit is faulty.
I would suggest rotating the Mode switch to Stitch, Spot, and back to Continuous a few times, and ensure that the Timer pot - at the top - is set to zero.
