Miller 625 extreme with CNC kit wiring

Hello from near Boston

getting my THC going with a Miller 625 extreme… correct me it I’m wrong please

the Brown (+) wire (the work) and the Brown/white (-) wire (the torch) provide the proper 50:1 output division for the THC directly…

how (ie which color wires) should they be connected to in the Langmuir THC pig tail?

tnx in advance
Mike, K1FNX
