Command table (6 of 14)
ID Command System Description
087 BROADCAST MODE Manual gas system
Auto gas system
Tell all systems to listen but not respond.
Data:
None
Return value:
None
Sample:
>0879F<
no response
094 READ_GAS_PRESSURES Manual gas system
Auto gas system
Read the gas pressures.
Data:
None
Return value:
Plasma cutflow pressure (psi),
Plasma preflow pressure (psi),
Shield cutflow pressure (psi),
Shield preflow pressure (psi),
Cut gas 1 pressure (psi),
Cut gas 2 pressure (psi),
N
2
Mix inlet pressure (psi),
Gas2 Mix inlet pressure (psi)
space-delimited
Values are in psi (0007 = 7 psi)

095 SET_ALL_PARAMETERS Auto gas system Set all variables to run the plasma system. If inlet gases
change power supply will enter the purge state. Gas
type changes are not allowed when the system is
cutting (state 4 – state 10).
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.
Data:
Current setpoint (5 – 130/260/400 amps),
Corner current percent (50 - 100%),
Plasma gas type code (use table VI),
Shield gas type code (use table VI),
Plasma cutflow setpoint (0 – 99 psi),
Plasma preflow setpoint (0 – 99 psi),
Shield cutflow setpoint ( 0 – 99 psi),
Shield preflow setpoint (0 – 99 psi),
N
2
mix setpoint (0 – 100 psi),
Gas 2 mix setpoint (0 – 100 psi),
space-delimited.
Return value:
1= accepted, 0 = not accepted
