4. Plasma Power Supply Enable / Disable Switch
The DISABLE position removes input power from the Power Supply inverters, disables the coolant pump and
fan, the pilot contactor & HF and removes AC power from the gsa control solenoids shutting off all gas flow.
When the switch is returned to the ENABLE position an automatic gas purge is started and then the system is
returned to normal operation under control of the CNC device.
5. PREFLOW Control Knob and Pressure Gauge
Used to set preflow gas pressure. MODE switch must be in SET PREFLOW position.
6. PLASMA and SHIELD Control Knobs, Pressure Gauges, and Flow Meters
Used to set plasma and shield gas pressures and flows. MODE switch must be in SET PLASMA & SHIELD
position.

O Mist Control Knob and Flow Meter
Used to set water flow rate. MODE switch must be in SET PLASMA & SHIELD position. GAS selection switch
must be in N

O position.
NOTE
Water mist is not used in all applications. Ohmic height sensing is not recommended with water mist
shield. Water on the plate interferes electrically with the ohmic sensing system.
8. Shield Pressure / Flow Selector Switch
At lower flow rates the shield gas pressure is first set per the cut charts then the flow is set using the flow meter
with the Gas switch set in the “Flow” position. Some torch parts require higher flow rates that exceed the
capacity of the flow meter. In those cases, set the Gas switch to the Pressure position and use the regulator and
gauge to set the pressure per the cut charts.
