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.
7.2.2.5
Alarm indication when target is achieved
When any of the number of welding points, wire consumption and total welding time reaches the target
specified, its corresponding control No. will flash.
7.2.2.6
Alarm indication at the time of WARNING detection (Welding Monitor "P45"
"P46")
If the average current or average voltage becomes out of the specified range, the difference between the
average value and the specified value will flash.
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)
• In the right example, the control No. "P20" flashes on the left
digital meter and the specified value "910" on the right digital
meter.
• The display returns to the normal state when any key of the
operation panel is pressed.
• If continuous operation is enabled in the setting of the
operation for the time when the target is achieved, an alarm
will display every time welding finishes until any key of the
operation panel is pressed.
<Example> When wire consumption reached the target
value
• The right example shows a current error. The control No.
"P40" flashes on the left digital meter and the difference
between the average value and specified value "30" on the
right digital meter, with the "A" LED lighting.
<Example> While welding is conducted with the welding
current 200A/Current tolerance (+) 10% (= 220A), the
average current during welding rose to 230A and the
WARNING judgment time specified in "P45" elapsed.
