7.2.2.3 Total welding time
The total welding time is controlled according to the setting range.
• P30 (Cumulative total welding time)
Every interval from the start of current flowing triggered by the torch switch ON to the stop of output
triggered by the torch switch OFF is counted and accumulated as welding time.
The setting range of count value is between 0 and 999 minutes. The count value will be cleared according
to the "P32" setting. (If continuous operation is enabled, the value will be cleared when exceeding 999 and
returns to 0.)
• P31 (Target total welding time)
Select the target value of total welding time in the range from 0 to 999 minutes.
When the "P30" count value reaches the total welding time specified here, an alarm displays indicating
that the target is achieved. (

-
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)" (

7.2.2.4 Welding monitor
Average current/voltage during welding is monitored. When it exceeds the range specified here, an
alarm displays and the output stops.
• 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.
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" % (= 220A)
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.
