Name Description Corrective action
043
High preflow
pressure
Gas pressure is above the
upper limit of 6.8 bar
(99 psi)
1. Verify gas supply pressure settings.
2. Verify gas regulator settings on gas console with cut chart.
3. See Setting the supply regulators (Installation section).
4. 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.
044
Low plasma
gas pressure
Gas pressure is below the
lower limit of 3.5 bar
(50 psi)
1. Inspect gas supply pressure and volume of gas remaining in
supply tanks.
2. Verify gas regulator settings on the front panel of the power
supply with cut chart.
3. See Setting the supply regulators (Installation section).
4. Fuel-gas only – Perform leak test procedure
(Maintenance section).
045
High plasma
gas pressure
Gas pressure above the
upper limit of 6.8 bar
(99 psi)
1. Verify gas supply pressure settings.
2. Verify plasma gas regulator settings on the front panel of the
power supply with cut chart.
3. See Setting the supply regulators (Installation section).
4. 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.
046
Low line
voltage
Line voltage is close to or
below the lower limit of
102 VAC (120 VAC
–15%). The normal lower
limit for operation is 108
VAC (120 VAC –10%).
1. Verify input-line voltage. Voltage needs to be within 10 % of
nominal (120 VAC).
2. Verify fuses on PCB3.
3. Verify 120 VAC voltage on plug J3.4, pins 3 and 4 on
PCB3.
4. If AC voltage on J3.4, pins 3 and 4, is greater than
108 VAC, replace PCB3.
047
High line
voltage
Line voltage is close to or
above the upper limit of
138 VAC (120 VAC
+15%). The normal upper
limit for operation is 132
VAC (120 VAC +10%).
1. Verify input-line voltage. Voltage needs to be within 10 % of
nominal (120 VAC).
2. Verify fuses on PCB3.
3. Verify 120 VAC voltage on plug J3.4, pins 3 and 4 on
PCB3.
4. If AC voltage on J3.4, pins 3 and 4, is less than
132 VAC, replace PCB3.
