N
2
mix setpoint and Gas 2 mix setpoint are only applicable
when using a mixed plasma gas such as H35 – N
2
.
Otherwise, these 2 values should be set to 0.
A value of 0 for N
2
mix setpoint will cause the system to close
SV12, the solenoid valve for N
2
mixing. A value of 0 for Gas 2
Mix Setpoint will cause the system to close SV13 and open
SV14. This will cause the inlet gas to bypass motor valve 2
and pass directly to the outlet of the mixing console.
