The input voltage exceeds allowable range (higher than AC 437V).
After input voltage returns within the allowable range,
B
then turn power switch back ON again.
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.
B
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.
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
B
feeder and shielding gas flow are stopped automatically.
Switch off power source switch, remove the cause of thearc ignition error.
The torch switch was turned on before turning on the power switch.
Turn welding gun switch or inching wire feeding button
A
OFF.
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).
B
This product is defective.
Check if the current or voltage is applied to the
secondary side of this product from an external device.
The external equipment the connecting to output terminal block receives interruption
A signal " temporary stop 1".
Remove the cause on the external equipment side.
Check the level of coolant in the cooling circulation system.
check that whether the cooling system is clear or not.

Attention:For the first time, this alarm will appear when the coolant loop is not fulfilled
with the liquid. After fulfilling with coolant, the alarm will resume automatically.
Group Probable causes and remedy
Abnormal RAM.
B restart power source, confirm the data of F. Adj
menu. If data disappears, please set again.
