When you use the hand torch on any of the Hypertherm systems the remote start input is disabled.....as the hand torch is designed to be operated using the trigger switch for hand cutting applications. With a machine torch installed (does not have a trigger switch) the start input wiring is active. This is a safety precaution to minimize the chance of a hand torch being fired from a remote location.
If you are using the hand torch for a mechanized application (many users do) then you will have to trace the torch trigger switch wiring to splice the start signal. The output from the CandCNC electronics is a simple contact closure, which is exactly what the torch trigger switch does on the hand torch.
Unfortunately, as a Hypertherm employee I cannot help you make the connections to the hand torch that will effectively bypass our safety circuitry. Tom at CandCNC is familiar with the Hypertherm systems and may be able to offer guidance on these simple connections.
