It’s specific to the 45XP hand torch. Zip tie the trigger and the #6 pin has to be removed from the connection assembly and inserted into the #8 port. This bypasses the trigger safety and lets the CNC port fire the torch.
To clarify a little, the Hyperthem knows whether a hand torch or machine torch is being used based on the position of that wire. Even with the trigger zip tied, a hand torch will not fire with a signal to the CNC. Moving that pin tells the HT a machine torch is being used and allows use of the CNC port.
