functions and features

The Shield Gas Box selects different gases (Air, N2, O2, CH4) to mix shield gas (SG), plasma gas 1 (PG1), and plasma
gas 2 (PG2). The selections are done through a group of solenoids integrated on a manifold. The CNC sends
commands through CAN-bus to operate all these solenoids. The gas output of the Shield Gas Box is monitored
and fed back through the CAN-bus to CNC for self-diagnosis. Also, the Shield Gas Box controls the solenoid for
operation of the Air Curtain.
The default power input to Shield Gas Box is 230VAC. However, the Shield Gas Box input power is customer
selectable, between 115 VAC and 230 VAC. This is accomplished by changing the input power switch inside the
Shield Gas Box. The Shield Gas Box provides 24VDC and 24VAC power for the Plasma Gas Box.
