When start selected torch on shuts off immediately. G code program generated in fusion. FC is running g codes. Plasma cutter is operational. This setup has worked for my system prior. No THS. What might be issue here why torch on shuts off when start is clicked?
I’m not understanding your issue. The torch is turned on and off by the G-code after hitting the start button.
The torch on button in Firecontrol is only for testing the torch or manually cutting a straight line.

That helps, then the G code must not be firing the torch. What is g code for starting the torch and shutting off?
M3 fires the torch.
M5 turns it off.
There are several reasons the torch won’t fire, but G code is way down at the bottom of the list.
Does the torch fire when you hit the manual torch fire button in Firecontrol?
Do you have a hand torch that you can test by pulling the trigger?
Some of the most common reasons the torch won’t fire are:
- torch on/off wire is not connected or broken.
- air pressure is too low or not connected
- torch consumables are installed incorrectly
- torch consumables are worn out or stuck.
- torch on/off relay in the control box is bad.
