7.2.2.7 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.
7.3 Data Backup (Utilization of data)
This section explains about backup of data such as welding conditions and importing of the backup data.
The following contents can be backed up as csv files in USB flash drive and also imported to the welding
power source.
Backup data can be used for the following applications.
• Copying the same setting to another welding power source
• Analyzing output waveform at the time of failure
• 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.
• The right example shows a voltage error. The control No.
"P40" flashes on the left digital meter and the difference
between the average value and specified value "1.5" on the
right digital meter, with the "A" LED lighting.
In case of voltage error, the difference between the average
voltage and specified voltage is displayed in one decimal
place.
• The display returns to the normal state when any key of the
operation panel is pressed.
• If continuous operation is disabled ("1" or "2" is selected) in
the "P46" setting, next welding cannot start until any key of
the operation panel is pressed.
<Example> While welding is conducted with the welding
voltage 15V/Voltage tolerance (+) 0% (= 15V), the
average voltage during welding rose to 16.5V and the
WARNING judgment time specified in "P45" elapsed.
