1) “E-000” blinking -Operation Stop –
When the STOP terminals of the 12P terminal block (TM5) for external connection are open, “E-”
and “000” in the displays blink and the welding power source stop. To release this error, shut off
the power switch and then short-circuit the STOP terminals and then turn on the power switch
again.
Note: When in “auto” mode to release “Operation Stop”, it is only needed to short-circuit
terminals to remove this abnormality without turning on the power switch again.
Refer to Section “10.2.1 (4) Switch of Auto/Semi-auto Mode” for more details.
2) “E-010” blinking -Torch switch off state waiting-
Typically, after turning on the power switch, the machine will switch to an operating state 1 second
after the digital meters display “000” and “000”. But if the welding torch switch remains on, the
welding power source will hold a halt condition, then “E-” and “010” shown in the displays will blink.
To release this error, turn off the welding torch switch, and then normal operation is available.
3) “E-100” blinking -Control power supply error-
When the control power source has an abnormality, “E-100” in the display will blink, and the
welding power source will automatically stop operation. Check the CN9 on the circuit board
P30110P and the connecting wire of the auxiliary transformer, and then turn on the power supply
again to remove this abnormality.
4) “E-150” blinking -Excessive Primary Input Voltage –
When an Excessive Primary Input Voltage occurs, “E-150” will be displayed flickeringly, and the
welding power source will automatically stop operation. Shut off the power switch, verify the circuit
board P30161X is switched the right voltage and verify the three-phase input voltage of the power
supply to check eliminate the breakdown, and then turn on the power supply again to remove this
abnormality.
