• P33 (Setting of voltage upper limit)
• P34 (Setting of voltage lower limit)
Set the allowable tolerance range of the welding voltage from 0 to 100V.
• P35 (WARNING judgment time)
Set the time to judge an event as an error in the range from 0 to 100 seconds when the average current/
voltage (average per second) during welding is outside the allowable tolerance range.
When the out-of-range state exceeds the time specified here, an alarm is displayed. ( 7.2.2.5

Alarm
indication at the time of WARNING detection (Welding Monitor "P35" "P36"))
If "0" is set, WARNING detection is not performed.
• P36 (Operation at the time of WARNING detection)
Set 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.
• Alarm signal output function to external output terminal
If the average current/voltage (average per second) during welding falls outside the tolerance range set
by "P31" to "P34", the external output terminals set by the internal functions will be shorted.
（

F25 to F28: External output terminal setting
）
The shorted external output terminals open when any of the following conditions are met.
– When some key on the panel is pressed while the alarm is displayed and normal display is restored.
– When the torch switch is set to “ON” while an alarm is displayed to start welding (only when P36 is
set to "0")
– When operation is stopped by releasing 3-4 (operation stop terminal) on the external connection
terminal block TM3 during alarm indication, and then the operation stop is canceled by short-
circuiting these terminals (only when F4 setting is "1" or "2").
7.2.2.4 Alarm indication when target is achieved
When any of the number of welding points, total welding time reaches the target specified, its
corresponding control No. 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.
