I have a Miller CP252TS power supply that I want to connect to a new LN-7 Lincoln wire feed unit. I have looked at the available schematics and can find no information on the pin locations on the control cable from the LN-7 to the power supply or any info on the wire colors in the cord. Anybody out there have any info on the LN-7 plug or wire colors/pin location? And does the 115vac circuit or the 25vac circuit in the miller energize the weld power?
