E-09
OUT LIMIT OF
PULSE WIDTH
ERROR Welding Current pulse width is out of
PULSE HI setting range on MONITOR
SET screen.
Check that the transformer capacity is
sufficient.
Check workpiece and welding electrode.
E-10
SET ERROR
Primary current of turn ratio is out of range
of the following formula:
IS-2200CA : X = 45, Y = 2200
IS-4500CA : X = 90, Y = 4500
Correct each setting.
The WELD1 , WELD2 , and WELD3
values are all “0.”
The total time of UP SLOPE and DOWN
SLOPE is longer than the WELD time.
HEAT setting, including RATIO setting is
equal to or lower than UF or DL setting.
Although STEPPER MODE is set to
LINER or FIXED, STEPPER COUNT of
STEP number set for START ON STEP#
are all “0.”
The series of welding currents in WELDs
without COOL are different than the
consecutive UP/DOWN settings.
UP/DOWN is set in the consecutive portion
of a series of WELDs without COOL and
the portion meets specific conditions.
On ADVANCED Power Supply models
the transformer weld frequency was set
greater than 1000Hz
E-11
SET OVER
HEAT setting (including RATIO setting)
is equal to or lower than UF or DL setting.
Correct each setting.
HEAT setting (including RATIO setting)
is larger than the maximum current,
voltage, or power setting.
HEAT setting (including RATIO setting)
is lower than the minimum value of current,
voltage, or power setting.
