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 thearc 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
