code Error cause Action and how to cancel error
E- 000 There is no load between the
STOP terminals (*1)
• Identify the cause of no load between the STOP terminals (3-4) of the terminal
block TM3 for external connection.
• How to clear the error code indication differs depending on the setting of
internal function F4. ( 6.7.2.4
-
F4: Auto/Semi-auto mode)
E- 010 The torch switch was on when
the power switch was turned on
(*1)
• Check that the torch switch is not on (not pressed).
• If the internal functions F29 to F32 are set to "4" (activate), check also the
connections of the terminal blocks for external connection. ( 6.7.2.23
-
F29
to F32: External input terminal setting)
• The error code will disappear when the status above is resolved.
E- 011 Torch switch ON continuously
without arc start (*1)
• Check that the torch switch is not on(not pressed).
• The error code will disappear when status above is resolved.
E- 020 Inching was active when the
power switch was turned on (*1)
• Check that the WIRE INCH key (or inching button) is not pressed.
• If the internal functions F29 to F32 are set to "2" (inching), check also the
connections of the terminal blocks for external connection. ( 6.7.2.23
-
F29
to F32: External input terminal setting)
• The error code will disappear when the status above is resolved.
E- 030
to
037
Installing the software from a
USB flash drive failed (*1)
• Check that the USB flash drive is normal and connected to the USB connector
correctly, and try installing again.
• The error code will disappear when the power switch is turned off.
E- 100 Error of control power (*1)
• If cables are drawn out of the welding power source, check that there is no
abnormality (e.g., short-circuit) in the cables.
• The error code will disappear when the power switch is turned off.
E- 150 The input voltage for primary
side exceeded the allowable
range (*1)
• Check that the input voltage for primary side is between 340 to 460 V.
• The error code will disappear when the power switch is turned off.
E- 160 The input voltage for primary
side fell below the allowable
range (*2)
• Check that the input voltage for primary side is between 340 to 460 V.
• Check the set value of internal function F20. ( 6.7.2.17
-
F20: Low input
voltage detection level)
• The error code will disappear when the power switch is turned off.
E- 210 The arc voltage was not
detected (*1)
• Check that the power cables such as cables for base metal side and torch
side and the voltage detection cable are not disconnected.
• The error code will disappear when the power switch is turned off.
E- 300
to
303
The temperature inside the
welding power source exceeded
the allowable range (*1)
• Leave it untouched (with the power on) and operate the cooling fan for 10
minutes or more, and then turn off the power.
• After the above, clean dusts inside the welding power source. ( 8.3
-
Periodical Inspection)
• The error code will disappear when the power switch is turned off.
• After recovery, be careful not to exceed the rated duty cycle.
E- 310
to
313
Rotation problem of the cooling
fan (*2)
• Clean dusts inside the welding power source. ( 8.3
-
Periodical Inspection)
(Cooling fan may not work normally due to powder dust or foreign matter.)
• If the problem persists, the cooling fan may be broken. Contact your dealer.
• The error code will disappear when any key of the operation panel is pressed.
E- 510 Water-cooled pump abnormally
(*1)
• Check for water leakage from the cooling water hose and ensure that
sufficient cooling water is available.
When using the air-cooled torch, check that LED of the TORCH key on the
operation panel is off.
E- 615 Error of the backup memory
data (*2)
• The error code will disappear when any key of the operation panel is pressed.
• At the time, the welding conditions specified/registered and the settings of
internal functions may be initialized. After the error is cleared, check that
there is no problem in the data.
