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. ( 6.7.2.21
-
F29
to F32: External input terminal setting)
• The error code will disappear when the status above is resolved.
E- 020 Inching was active when the
power switch was turned on (*1)
• Check that the INCHING 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. ( 6.7.2.21
-
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 the range of (208/230/460 V
± 10 %).
• The error code will disappear when the power switch is turned off.
E- 155 The input voltage for primary
side was out of allowable range
from 265 to 320 V (*1)
• Check that the input voltage for primary side is the range of (208/230/460 V
± 10 %).
• 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 the range of (208/230/460 V
± 10 %).
• Check the set value of internal function F20. ( 6.7.2.15
-
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
304
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- 320 When using a single phase
power, the power source
exceeds the rated duty cycle
(*1)
• When using a single phase power, check that power is at 60 % rated duty
cycle.
• The error code will disappear when the power switch is turned off.
E- 500 Lack of water pressure (*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.
