I have a Hypertherm PowerMax 105 connected to a Torchmate 5x10 table with a machine torch. How do I use a hand held torch to just make quick cuts from scrap? Do I have to unplug the cnc control cables from the back? Then just plug in the hand torch. Or can I leave everything hooked up and just change out the machine torch to the handheld torch but not turn on the program? Thanks in advance.
