8. Error Code 

8-2 

 

No. 

Name of fault displayed on the screen 

Explanation of fault and corrective measures 

E06 

OUT LIMIT OF CURRENT 

The measured value of welding current has been outside of the 

monitor range set on the COMPARATOR screen. 

E07 

OUT LIMIT OF VOLTAGE 

The measured voltage between electrodes has been outside of the 

monitor range set on the COMPARATOR screen. 

E08 

OUT LIMIT OF POWER

 

The measured welding power has been outside of the monitor range 

set on the COMPARATOR screen. 

E12 

CHARGE TROUBLE(LACK) 

Failure of charging circuit. 

This message appears when charging is not completed within 7 

seconds after power is turned on. 

Turn off the power immediately and contact us or your distributor. 

E13 

CHARGE TROUBLE(OVER) 

Failure of the charging circuit. 

Displayed when the charging voltage is too high. 

Turn off the power immediately and contact us or your distributor. 

E14 

TRANSISTOR TROUBLE 

Fault of the welding control circuit. 

Welding current is output continuously. 

Turn off the power immediately and contact us or your distributor. 

E15 

PRECHECK ERROR 

Displayed when the current exceeds the upper or lower limit of the 

current range set on the PRECHECK screen when the precheck 

weld is used. 

Check the contact of electrodes and the state of the weldment. 

E16 

ABORT 

The jumper wires between No.1 and No.3 (STOP) of terminals on 

the rear panel are disconnected. 

E17 

START PARITY ERROR 

Displayed when a parity error occurs during operation with 

SCHEDULE# set to EXT.(P). (Refer to 

6.(6)

SCHEDULE

.) 

E18 

COUNT MEMORY TROUBLE 

Counts of GOOD COUNT are damaged. 

The following are conceivable causes of damage of counted data. 

・

 Strong power noise and electrostatic noise 

・

 Faults in the supply voltage due to thunderbolts or lightning 

conduction 

・

 Decrease in voltage of battery for memory backup 

E19 

VOLT SENS ERROR 

The V SENS cable is broken or disconnected. 

Confirm the connection of the V SENS cable. 

When the V SENS cable  is not connected in the constant-current 

control, short on Terminals 36 and 37.
