Troubleshooting
48
Err S/N Error type Group Probable causes and remedy
Err 004
primary over-
voltage
B
The input voltage exceeds allowable range (higher than AC 437V).
After input voltage returns within the allowable range,
then turn power switch back ON again.
Err 005
primary under-
voltage
B
The input voltage is lower than allowable range (lower than AC 304V) or input power
source phase failure happens.
After input voltage returns within the allowable range, then turn power switch back
ON again.
Note: when welding machine input power source phase failure happens, apart from
ERR-5, the operation PCB shows nothing (i.e. LED indicator and LED display are not
lit), or operation PCB LED indicator and LED display
alternately flashes.
Err 006 Arc Start error B
Neither arc is generated nor no-load voltage is detected when the torch switch is
turned on.
When the “Arc Start” error occurs, the welding current output, motor of the wire
feeder and shielding gas flow are stopped automatically.
Switch off power source switch, remove the cause of the arc ignition error.
Err 007
welding gun
switch error A
The torch switch was turned on before turning on the power switch.
Turn welding gun switch or inching wire feeding button
OFF.
Err 008
current detection
error
B
Output current or voltage is detected when the power switch is turned on.
<Remedy>
Turn power switch OFF and then check the followings to remove the cause(s).
This product is defective.
Check if the current or voltage is applied to the
secondary side of this product from an external device.
Err 010
external
interruption 1
A
The external equipment the connecting to output terminal block receives interruption
signal “ temporary stop 1”.
Remove the cause on the external equipment side.
Err 011
external
interruption 2
A
The external equipment the connecting to output terminal block receives interruption
signal “ temporary stop 2”.
Remove the cause on the external equipment side.
Err 019
wire adhesion
error B
When the Product works with special purpose machine or robot, wire adhesion at the
end of welding.
switch off power source switch and cut the welding wire.
Err 025
motor encoder
error
B
Abnormal encoder feedback
Switch off power source switch to eliminate arc abnormal ignition factor.
Err 028
wire feeder over-
current
error
B
The wire feeding route is blocked, causing over-load of the motor.
clean the wire feeding route ( contact tip, wire feeding
liner and wire feeding roller etc.).

Err S/N Error type Group Probable causes and remedy
Err 030
RAM
error
B
Abnormal RAM.
restart power source, confirm the data of F. Adj
menu. If data disappears, please set again.
Err 050
communication
error
B
Abnormal communication.
restart power source.
