1. Check the interface cable for damage. The hold wires may
be short-circuiting inside.
2. The CNC is maintaining this input, it could be waiting for an
IHS complete input from another torch.
3. If CNC interface cable is good and it is a one-torch system,
change PCB3.
Plasma gas pressure
under lower limit of
1. Inspect gas supply pressure and volume of gas remaining in
supply tanks.
0.34 bar (5 psi) – pre-flow 2. Verify gas regulator settings on gas console with cut chart.
3.45 bar (50 psi) – cutflow
(cutting)
3. See how to set your supply regulators (
Installation
section).

section).
1. Verify gas supply pressure settings.
2. Verify gas regulator settings on gas console with cut chart.
3. See how to set your 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.
1. Verify input-line voltage. Voltage needs to be within 10 % of
nominal (120 VAC).
2. Verify fuses on PCB2.
3. Verify 120 VAC voltage on plug J2.4, pins 3 and 4 on PCB2.
4. Verify voltage on receptacle J2 on PCB2. Should be
approximately 1.65 VDC between pins 1 and 2.
5. If AC voltage on J2.4, pins 3 and 4, is greater than 108 VAC
and DC voltage on J2 is less than 1.485 VDC, replace PCB2.

3. Verify 120 VAC voltage on plug J2.4, pins 3 and 4 on PCB2.
4. Verify voltage on receptacle J2 on PCB2. Should be
approximately 1.65 VDC between pins 1 and 2.
5. If AC voltage on J2.4, pins 3 and 4, is less than 132 VAC and
DC voltage on J2 is greater than 1.815 VDC, replace PCB2.
6. If AC voltage on J2.4, pins 3 and 4, is less than 132 VAC and
DC voltage on J2 is less than 1.815 VDC , verify the DC voltage
to J3.201 on PCB3. It should equal the voltage reading on J2. If
the DC voltage readings are the same and the wiring passes
continuity tests, replace PCB3.
6. If AC voltage on J2.4, pins 3 and 4, is greater than 108 VAC
and DC voltage on J2 is also greater than 1.485 VDC, verify
the DC voltage to J3.201 on PCB3. It should equal the voltage
reading on J2. If the DC voltage readings are the same and the
wiring passes continuity tests, replace PCB3.

Low line
voltage
Line voltage is close to or
less than the lower limit of
102 VAC (120 VAC -15%).
The normal lower limit for
operation is 108 VAC (120

Line voltage is close to or
greater than the upper
