This May Mean Cause Solution
Start LED on control board
(PCB3) and Fault lamp are
illuminated Continuous start signal Shorted start wires or
depressed start trigger
switch Check start wires (blue
and orange wires in torch)
for short.
Receiving start signal from
CNC Check CNC cable for start
signal (Machine interface
pins 3 and 4).
Start and XFR LEDs on
control board (PCB3) Arc transfer Normal operation N/A
SDF LED on control board
(PCB3) and Fault lamp are
illuminated Self diagnostic failure Microprocessor failure Replace control board
(PCB3). If SDF LED
persists replace power
board (PCB2).
Start and IF LEDs on
control board (PCB3) and
Fault lamp are illuminated Invertor interlock No current from invertor,
power board (PCB2),
control board (PCB3), or
IGBTs
Start and TSO LEDs on
control board (PCB3) Torch stuck in open
position Torch plunger stuck,
consumables are worn, or
defective Pilot Arc IGBT See Resistance Check
#3, in this section.
Start and SP LEDs on control
board (PCB3) and Fault lamp
are illuminated LED is for future use N/A N/A
