Need help with my Oerlikon 420 Citopuls

[drmarty]

I've have bought a second hand Oerlikon 420 Citopuls MXW.

However it seems that's not working. The problem is that it wont weld.

When i power on the machine evertyhing seems okay so no fault codes. Also the watercooling pump runs.
I have gas, 400volts, feeding wire, a new ground cable.

But when i press the trigger the wires comes out but no welding.

Anyone has ideas what i can check?
