5 – Troubleshooting and System Tests
The gas pressure and
temperature LEDs blink
when the system is
powered ON (I).
• The system was
powered on while the
plasma start signal
was being sent.
• The system was
powered on with the
torch trigger being
pulled.
• The start circuit is
stuck closed.
• Release the torch trigger and
reset the system by turning it
OFF (O), and then turn it ON (I)
again.
The temperature, gas
pressure, and power ON
LEDs blink, and the torch
cap LED illuminates.
• The inverter is
saturated.
• The inverter is in an
over-current condition.
• The torch was
repeatedly fired with
worn out consumables.
• Install new consumables in the
torch (they may be corroded or
approaching end of life).
• If you continue to see this error,
replace the power board.
All four LEDs blink when
the system is powered ON
(I).
• A major fault has
occurred in the power
supply.
• The fan, solenoid valve,
control board, or
power board is faulty.
• The error LED on the control
board should be blinking. The
number of times it blinks
between pauses indicates
which components to test. See
Control board LEDs on
page 69.
The power-ON LED
illuminates but no fault
LEDs illuminate, and no
gas flows when you pull
the torch trigger.
• The start signal is not
reaching the control
board.
• The torch or torch lead
is damaged.
• The power board is
faulty.
• The control board is
faulty.
• Inspect the torch and torch
lead, and replace if necessary.
• Verify that the control board
start LED illuminates when you
pull the trigger. If it does not,
perform
Gas flows when the
system is powered ON (I).
• The incoming gas
pressure is too high.
• The gas pressure from
the compressor or
cylinder is too high.
• The gas solenoid valve
is faulty.
• Verify that the gas supply does
not exceed 9.3 bar (135 psi),
and reduce the pressure if
necessary.
