It seems that it is not easy to located the correct trigger wires for remote start. I used a multimeter and found the wires in the handle that connect when the trigger is pulled. That did not work. I am updating my cnc plasma table with a new Hyperherm Powermax45. I need to connect the remote start connectors on my CandCnc DTHC card to the wires coming from the start trigger on the hand torch. The wiring diagram shows that the pulling the trigger connects the violet to the blue wire. (#1 to #3 wire). I put a vampire tap on each of the wires (inside of the case) and run wires back to my DTCH card and plug them onto the correct spot. Upon testing I get a "torch stuck on/off" error message on the Powermax45. This same technique worked fine on my older Thermal Dynamics machine. The Hypertherm has a safety switch in the handle that is bypassed when I use this method and I assume the error is a resulting from bypassing the safety switch. Should I tape the trigger on the hand torch closed and wire my remote start "inline" on the single trigger wire? I sure would appreciate comments from anyone who has wired up one of these Powermax45 for CNC applications. I do have the manuals from their website but it does not help on how to do this. Also I have read 2 articles from this forum but they did not cover this topic.
Thanks in advance.
