I have the on/off pendant for my hypertherm 1250 but I'm not sure if I can use it,,the instructions for the arc voltage height control say's that to hook up the torch start switch I need to hook up through an interface cable which hooks up to the same spot as the on/off pendant. Which do I need,,the on/off pendant or the interface cable???

If you hook the Arc Voltage Height control into the CNC Interface Port on the back of the 1250, all of the torches on and off commands will be received by the table itself. If you leave the remote on/off pendant in that port, then the machine will not be able to activate the plasma cutter through programming.

There is an Auxiliary option in the software itself if you need to be able to manually turn the torch on and off, which is usually rare and few between.
