What is the extra connection on my Hypertherm Powermax 1000 G3 (not CPC)

I have a Hypertherm Powermax 1000 G3 with a Duramax MRT machine torch.

I use the torch fire wires on the 14pin CPC #3 and #4 just like the current Powermax line up. But there’s another cord on the back of the machine that uses a 3.5mm (maybe) jack and I have no clue what it’s for. I couldn’t find it in the manual (but I probably skimmed right over it). We don’t use ohmic sensing or Arc Voltage Control on the Crossfire so every input/output other than torch fire are not in use. But I was under the impression ohmic sensing was wired from the retaining cap on the torch to the electronics on a plasma table with that feature for touch off and e stop and I thought the AVC feedback wires were integrated into the 14pin CPC.

The reason I’m curious about it is I’m purchasing a 5x10 with THC and want to use this Powermax 1000 for at least the rest of the year before moving to a Powermax85. The table manufacture wasn’t much help because they only sell and recommend the 45xp/65/86, they had no idea what I was talking about. But it was also more of a sales guy than a tech. Either way, they should be familiar with this stuff but ah well.

If anyone runs across this, I read that it’s RAW arc voltage. Not to be confused or substituted for a divided arc voltage output (1:20 or 1:50) that’s typically wired through the CPC port at pins #5 and #6.

I have a powermax 1000 G3 series also. But I have a hand torch. What all do I need to do for wiring the plasma cutter? Will I need to zip tie the hand torch switch “on”? Thanks, Ken

I never had the hand torch for my PM1000 so I’m not sure exactly what pin you’ll have to change but they’re probably in the manual. You’ll have to change a wire and zip tie the trigger just like they do here with the 45XP

The powermax 1000 does not have a cnc port. Dealing with raw voltage, what terminals in the cutter did you hook the red and black wires coming from the VIM box to. I hooked the red “clamp” wire to J15+ and the black wire “torch” to J16-. I’m not sure if this is correct or not. Thanks, Ken

Some PM1000 did have the CPC port, mine did. Yes, those connections at correct for the raw voltage source.
