Error code
number
Name Description corrective action
054
High
shield gas
pressure
Shield gas pressure is over
upper limit of:
7.58 bar (110 psi) – manual
9.65 bar (140 psi) – auto
1. Verify gas supply regulator settings. See Setting the
supply regulators (Installation section).
2. Verify pressure settings on gas console with cut chart.
3. Solenoid at off-valve is not opening. Verify power to
valves, disconnect plasma and shield hoses exiting off-
valve. If pressures decrease, a valve is not functioning or
no power to the valve.
055
MV1 inlet
pressure
Auto gas
only
Motor valve 1 inlet pressure
is less than 3.45 bar
(50 psi) or greater than
9.65 bar (140 psi).
1. Verify that gas pressure transducer P1 is between 3.45
bar (50 psi) and 9.65 bar (140 psi). Increase or decrease
the inlet gas pressure to correct the problem.
056
MV2 inlet
pressure
Auto gas
only
Motor valve 2 inlet pressure
is less than 3.45 bar
(50 psi) or greater than
9.65 bar (140 psi).
1. Verify that gas pressure transducer P2 is between 3.45
bar (50 psi) and 9.65 bar (140 psi). Increase or decrease
the inlet gas pressure to correct the problem.
057
Cut gas 1
pressure
Auto gas
only
Cut gas 1 outlet pressure is
less than 3.45 bar
(50 psi) or greater than
9.65 bar (140 psi) in the
selection console.
1. Verify that gas pressure transducer P3 is between 3.45
bar (50 psi) and 9.65 bar (140 psi). Increase or decrease
the inlet gas pressure to correct the problem.
058
Cut gas 2
pressure
Auto gas
only
Cut gas 2 outlet pressure is
less than 3.45 bar
(50 psi) for non-mixing, or
less than 1.38 bar (20 psi)
when mixing or greater than
9.65 bar (140 psi) for non-
mixing and mixing.
1. Verify that gas pressure transducer P4 is between 3.45
bar (50 psi) and 9.65 bar (140 psi). Increase or decrease
the inlet gas pressure to correct the problem.
060
Low coolant
flow
Coolant flow is less than the
required 2.3 lpm
(0.6 gpm).
1. Verify that the correct consumables are properly installed.
2. Perform the coolant flow test procedure in the
Maintenance section of the manual.
061
No plasma
gas type
Manual gas - The gas
console control board is not
receiving signals from the
gas selector knob.
Auto gas - The selection
console is not receiving the
plasma gas type signal.
1. Auto gas - the process parameters may not have been
downloaded. Verify that the process information can be
viewed on the CNC screen.
2. Manual gas - the selector knob (2) may be set between
positions. Reset the knob.
3. Verify that there is power to the console by looking to
see if any LED on any board in the selection console
(auto) or gas console (manual) is illuminated. If no LED is
illuminated, verify that the fuse on the power distribution
PCB is in proper working condition.
4. If the problem still exists, replace the control board.
