Powermax 85 with CPC port, shipped from factory with 4 conductor power cable, red/blk/wht/grn conductors. It was incorrectly assumed for a 220v 1ph service that the red/blk were hot legs, the white was neutral, and the green was ground.

The system is currently not outputting torch volts from the CPC port however it otherwise functions normally. (The test conducted was to read DC volts across CPC pins 5&6 while jumping pins 3&4. Also, 1.5v was introduced into the J32 connector and only 1.5v was read across CPC pins 5&6)

It has since been realized (by looking more closely at the owners manual) that the white conductor should in fact NOT have been connected to neutral, but should only be used as the third conductor for a 3ph service. The system is now being powered from a 600v 3ph service but torch volts are still not being output.

My question is, how would the improper power wiring likely affect the Powermax torch volts output?

It is also mentioned here to hopefully help someone else down the road.
