I use a cutmastet 82, the hook up in the Langmuir directions are spot on. I’ll try to get a pic of my wiring for you. One thing to know with the thermal dynamics (TD) is the cut heights and pierce heights are different than a lot of what I see others running with razor welds or Hypertherm. If you’re running the hand torch you will have to run a minimum pierce time of I think 1 sec for the initial fire off. The TD machines have a purge process the initial fire and won’t let the torch fire immediately. I run the machine torch and it bypasses that. I also run shielded consumables and have great results.
