The CPC (circular plastic connectors) are available from many supply houses. Here are Hypertherm part numbers as well as manufacturer (Tyco) part numbers for the mating plug that attaches to the rear panel Hypertherm CPC connector.
The plug consists of a shell, a cable clamp, as well as 6 pins. The unfortunate thing is that the pins are crimp pins and require a tool that costs about $250. I suppose you could solder the wires in, or you can buy a complete cable from Hypertherm (about $80) with the plug on one end and nothing on the other end.
Hypertherm interface cable:
123966 25’ machine interface cable
Hypertherm Parts:
008202 Plug Shell $8.50
008192 Cable Clamp $9.50
008196 Pin $0.80 (6 required)
You can also get them from an electronic supply house….they are manufactured by Tyco, and are known as Amp CPC connectors. Here are the tyco numbers:
A1358-ND Plug Shell
A32516-ND Cable Clamp
A99521-ND Pins
Let me know what you are interfacing the Powermax45 to (PlasmaCam, Torchmate, CandCNC, other?) and I may be able to help you out as well as I keep these components in stock.
