The Hypertherm Powermax units (45, 1000, 1250 and 1650) all have available machine torches.....,when the machine torch is plugged into the quick connect receptacle, the power supply recognizes it and allows for the remote start signal to be accessed on the interface connector on the rear panel....this connector also has a 50:1 divided arc voltage output and an arc transferred signal.
The Hypertherm hand torches have a safety trigger switch, and a safety circuit that attempts to not allow having a separate remote start switch attached at the same time the hand torch is attached. This is done for safety reasons...Imagine a remote switch firing the hand torch when you did not want it to fire...such as when you are changing consumables, or when the torch is setting next to a high pressure gas cylinder. Hypertherm made these safety decisions a few years ago after an accident in the field caused a serious fire in a shop....because of misuse of a remote start input.
There are many in the field that have bypassed this circuitry......and it involves cutting and splicing wires in the torch handle, or in the power supply....unfortunately, because this circuit is designed as a safety circuit, I cannot offer you advice on how best to defeat it! I recomend either using the machine torch for machine cutting applications....or, if you use the hand torch you must modify the wiring to the trigger circuit at your own risk.
