Hi,
I worked for a company fixing welders and plasmas and was a service agent for Hypertherm.
The pins in the socket are for
1) Input to the Powermax45 open/closed contacts to start the arc. This is the equivalent of the trigger on a handheld torch
2) Output from the Powermax45 to the CNC controller, sometimes called 'ArcOK' or 'Motion' . It signals the CNC controller that the plasma arc has started
and is ready to cut, ie motion can be initiated.
3) Output of Powermax45 to TorchHeightContoller. The arc voltage is passively divide by 50 and supplied to the output pins as an analogue
voltage that can be used by the TorchHeigthtController or alternately the CNC controller to adjust the torch height. For example if the arc voltage
at the current instant is 145V then the output will be 145/50=2.9V
So the Powermax45 socket is pretty simple. What you should be asking is how your controller handles it outputs and whether you have a separate TorchHeightController?
