Does anyone know what the black box is for?
I have connected the wire to the torch but have no idea what the black box is for?
It says
Torch
Clamp
DIV Output
DIV Onput
PV Output
It’s your voltage input module. Or VIM
It changes either the raw or divided voltage from your plasma cutter to a voltage level that your electronics enclosure will understand.
(73:1 I think is the number that’s been mentioned before)
