You shouldn’t be using raw arc voltage at all unless you know your machine is set up for it. Many CNC tables (including the Pro I believe) can accommodate either but need a physical change on the circuit board. Usually just a jumper or pin switched. If you feed raw arc voltage to a table set up for a 1:20 or 1:50 divided signal, you’ll fry the board.
But I believe his question was whether or not a voltage signal for THC is even output while using the hand torch as opposed to the machine torch. I don’t see why it wouldn’t be, but I don’t know for sure.
