6.7.2.15 F19: Switching alarm setting
When alarm occurs, the output of welding power source can be stopped.
Yet for some alarm codes, it is possible to continue welding even if the alarm level is detected, which may
sometimes cause the alarm display to be ignored. Using the alarm setting switch function ensures to stop
the output from the welding power source.
•
[ON]: any alarm detection stops the output of welding power source.
•
[OFF]: alarm detection does not stop the output of welding power source.
Means to reset alarms is the same as those for errors, including restoration of the power. (

6.7.2.16 F20: Low input voltage detection level
Set the low input voltage detection level on the primary side. When the input voltage is lower than the
set value, an error code is displayed.
Set the value in the range of 260 to 400 V.
T I P S
• The factory default setting is 320 V. However, the specification of input voltage as welding
power source is the range of 340 to 460 V. If input voltage is lower than this range, it may
affect welding performance.
6.7.2.17 F21: Maximum cooling fan operation
The cooling fan can be rotated at the maximum rotation speed at all time.
•
[ON]: The cooling fan rotates at the maximum rotation speed at all time. Even when it is set to [ON],
ensure not to exceed the specified duty cycle. (
•
[OFF]: The cooling fan rotates in a control mode (power-saving operation) due to the temperature
detection inside the welding power source.
This mode is effective in saving power consumption and preventing suction of extra powder dusts.
6.7.2.18 F22: Operation sound switching
Set the operation sound not to be emitted.
•
[ON]: Pressing any key on the operation panel enables to sound the operation sound.
•
[OFF]: Pressing any key on the operation panel does not enable to sound any operation sound.
