Hey guys!

I am retrofitting an Oxytome HPC 30 with linux control, and i am finding some trouble interfacing with the nertajet generator.

This generator uses a shield gas and cut gas, which I believe I can handle easily with some valves triggered by my control system. I can also detect probe by my own system, and raise the torch with a stepper motor with high torque configuration.

My issue is the generator arc signal.
I am familiarized with getting the raw voltage through a divider and feeding the divided voltage through all types thc. But to trigger this arc signal in this device seems extremely complicated. I have the manuals but i cant find a place to connect my relays to trigger the arc.

Has anyone succeeded in doing so with this generator?

I can get any pictures needed

Thank you
