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
