Cause

Solution

The power
switch on the
front panel is
tripped.

Never turn it on again. Contact your dealer.

When turning on the
power switch, the
displays light.

Trouble with PL1.

Inspect PL1.

The line disconnect switch in the
switch box is not turned on.

Inspect the power
box.

The main
power lamp
PL1 does not
light.

When turning on the
power switch,
nothing appears in
the display.

The input cables are not surely
attached.

Inspect the input
cables.

The main power
lamp PL1 does not
light.

Refer to No.2 in this list.

Shortage of the input voltage

Check for proper
input voltage.

When turning
on the power
switch, nothing
appears in the
display.

PL1 lights.

Trouble with the power circuit.

After inspecting
PCB P10532Q,
replace them if
necessary.

When turning on the power switch, the
WARNING and TEMPERATURE
lamps light up and an error code
appears in the display,

Refer to Section 11.1, “How To
Solve an Error”.

The discharge valve of the gas
cylinder is closed.

Open the valve.

Lack of gas pressure of the gas
cylinder.

Check for proper
gas pressure.

Gas is not generated
when the GAS
CHECK key is
pressed.

Trouble with the gas
electromagnetic valve SOL.

Inspect the gas
electromagnetic
valve SOL.

Shield gas is
not generated
when the
torch switch is
pressed.

Gas is generated
when the GAS
CHECK key is
pressed.

Disconnection of the torch switch
cable or incomplete insertion to
receptacle.

Check the wiring
number 222 and
223.

The GAS CHECK lamp lights up.

Stop gas checking
by pressing the
GAS CHECK key.

Shield gas does not stop.

Trouble with the gas solenoid
valve SOL

Check for
operation of the
gas solenoid valve
of wire feeder.

Trouble with the inverter main
circuit

Turn off the power
switch, then
contact your
dealer.

When the torch switch is pressed, no-
load voltage is not output but shield
gas is generated.

Trouble with the control circuit

After inspecting
PCBP10265P or
P30051T replace
it if necessary.
