3.1.2 Gas Controller (GC)
The Gas Controller (GC) must be mounted within 8 ft. (2.44m) of the torch/base.
Secure the GC to the mounting surface using three ¼" or M6 bolts. Refer to the
mounting pattern shown in Section 2.7. Ensure the port on the side of the GC
marked "VENT" is not blocked. The GC is IP23 rated.
The plasma and shield hoses connecting the torch to the GC run inside the torch
leads for 6 ft. (1.83m) before breaking out to connect to the GC. As such, the GC
has to be mounted within 2 ft. (0.61m) of the torch lead routing.
To minimize high frequency interference from the arc starting circuit, it is
recommended that the GC be mounted as far as possible - 2 ft. (0.61m) - from the
torch leads with the control cables routed away from the torch leads.
All control/communication cables must be routed with a minimum separation of 2 ft.
(0.61m) from the torch leads and a minimum separation of 6 in. (152mm) from the
power leads.
Refer to Figure 1.
