E10 LOST
error
The arc discharge was not
performed or the weld time is over
5 ms shorter than the total setting
time of welding conditions.
At a start of
welding
Perform maintenance and
adjustment referring to “8. (4)
Check Items when LOST Error
Has Occurred.”
* This is displayed when “E05
Weld error” occurs.
E11
Weld
parameter
error
The welding conditions were set
out of the specified setting range.
At all times
Set the welding conditions
again within the setting range.
(Refer to *1, 2, 4, and 5 in “4.
(9) Welding Condition Setting
Screen.”)
E12 CPU
error
The welding power supply was
faulty.
At all times
If this error occurs after a
restart, repairing is required.
Make contact with us.
E13
Current limit
error
The current monitor value was out
of the set allowable range.
Immediately
after welding
Execute maintenance for the
electrode and workpieces.
* This is displayed when “E05
Weld error” occurs.
E14
Voltage limit
error
The voltage monitor value was out
of the set allowable range.
Immediately
after welding
Execute maintenance for the
electrode and workpieces.
* This is displayed when “E05
Weld error” occurs.
E15
Time limit
error
The time monitor value was out of
the set allowable range.
Immediately
after welding
Execute maintenance for the
electrode and workpieces.
* This is displayed when “E05
Weld error” occurs.
E16
GP
communi-
cation error
An error occurred in the
communication between the panel
unit and the main unit.
At all times
Check the connection cable
when extending the panel unit.
If the error cannot be cleared,
there is a possibility of any
component failure. Make
contact with us.
E17
Start1 - time
limit
exceeded
The H-ST2 signal (main welding
start) is turned on simultaneously or
before the H-ST1 signal (initial
current start).
At a start of
welding
Turn on the H-ST1 signal
before the H-ST2 signal.
E18
Start2 - time
limit
exceeded
Initial current time: 1 to 999 ms
The H-ST2 signal (main welding
start) is not turned on within the
initial current time after the H-ST1
signal (initial current start) is turned
on.
Initial current time: 0 ms
The H-ST2 signal (main welding
start) is not turned on within 500 ms
after the H-ST1 signal (initial
current start) is turned on.
At a start of
welding
Turn on the H-ST2 signal
within the initial current time
after the H-ST1 signal is
turned on.
Turn on the H-ST2 signal
within 500 ms after the H-ST1
signal is turned on.
E19
Torch1 - end
of counter
reached
“TOTAL COUNT” reached the
count of “PRESET.”
At an
operation
before
welding
Reset “TOTAL COUNT” to
zero or set “PRESET” again.
