You only need to monitor the cutting voltage of the arc.

depending on your plasma torch.
Thank you for your answer
I have a HF arc start with pilot arc functionality, there are 3 cables:
- thick cable for +, connected to torch
- thinn cable for pilot arc ignition, also connected to torch
- thick cable for -, connected to clamp which I attach to the material
I
want to cut.
Do I need 2 of the AD converters to monitor cutting arc and pilot arc?
What would be an appropriate resistor to protect the THCAD?
Best Regards,
Alexander
