P31 (Target total welding time)
Select the target value of total welding time in the range from 0 to 9999 minutes.
When the "P30" count value reaches the total welding time specified here, an alarm displays indicating that the target
is achieved. (
7.2.2.6
-
Alarm indication when target is achieved)
•
P 32 (Operation at the time when the target total welding time is achieved)
Select the operation from 0 to 5 for the time when the target specified for "P31" is achieved.
The set values and operations when the target is achieved are the same as those of the "P12" function. "P12 (Operation
at the time when the target number of welding points is achieved)" (

-
Number of welding point)

Average current/voltage during welding is monitored. When it exceeds the range specified here, an alarm displays and
the output stops. Also, by setting the internal functions (Functions), the welding power source can output the alarm signal
to the external output terminal when it exceeds the range. (

F25 to F28: External output terminal setting)
•
P40 (Max. fluctuation value of average range monitor)
If the average current/voltage (per second) becomes out of the allowable tolerance range specified in "P41" to "P44",
an alarm is displayed indicating the following. (

Alarm indication at the time of WARNING detection
(Welding Monitor "P45" "P46"))
•
P41 (Current tolerance (+))
P42 (Current tolerance (-))
P43 (Voltage tolerance (+))
P44 (Voltage tolerance (-))
Select the allowable tolerance range from 0 to 100 % in relation to the set values of welding current/ voltage.
Example: The "P41" to "P44" settings when the set value of welding current is 200A and that of welding voltage is 20 V.
•
P45 (WARNING judgment time)
Select the time to judge the event as an error in the range from 0 to 100 seconds when the average current/ voltage
(average per second) during welding is out of the allowable tolerance range.
When the out-of-range state becomes longer than the time specified here, an alarm displays. (

Alarm
indication at the time of WARNING detection (Welding Monitor "P45" "P46"))
If "0" is set, WARNING detection will not be performed.
•
P46 (Operation at the time of WARNING detection)
Select the operation at the time of WARNING detection from 0 to 2.
The set values and operations at the time of WARNING detection are as below.
If the current is out of the range
: Difference (A) between the set value and the average value of welding current
If the voltage is out of the range
: Difference (V) between the set value and the average value of welding voltage
If both the current and voltage are out of the
range
: Difference of either value which is more largely out of the range than the other
P41 (Current tolerance (+)) is set to "10" % (= 220 A)
P42 (Current tolerance (-)) is set to "20" % (= 160 A)
P43 (Voltage tolerance (+)) is set to "20" % (= 24 V)
P44 (Voltage tolerance (-)) is set to "10" % (= 18 V)
In the example above, the allowable tolerance range of welding current is 160 to 220 A and that of welding voltage is 18 to 24 V.
Set value
Operation
0
Alarm indication only. Welding can continue. (Continuous operation is possible)
1
The ongoing welding can continue.
After the welding is finished, next welding cannot start until any key of the operation panel is pressed. (Continuous operation
is not possible)
2
Welding stops immediately.
Next welding cannot start until any key of the operation panel is pressed. (Continuous operation is not possible)
