Hello! and thanks for responding. I have contacted Thermal Dynamics Tech Support and spoke with a couple of head personnel twice, months apart, and got the same response. " They don’t have any technical information or an inservice manual on this unit and not sure when. And the unit wasn’t designed for CNC application because of its low amperage". It was implied they haven’t opened up one for themselves, due to no service manual and it being new out in the field. Thank you for the input on wiring in the Torch. I myself am not comfortable opening and experimenting without some technical guidance. Hopefully, someone has opened one up for the same purpose.
