I have to wire up a plug to go into the front of my plasma cutter, Unimig Cut45, it says in the instructions that PIN 3-4 is used to trigger the ON/OFF signal. I have wired the PIN 5-6 to plug into the DIV input port for the THC but am wondering how to setup the PIN 3-4 to trigger the ON/OFF signal. Does it plug into the PV Output and does it matter what color wire goes into 2 or 3. Hope this makes sense, it seems to in my head. Thanks
Don’t worry, think i just figured it out, when all else fails read the instructions.
