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.
