6.7.2.15 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.
6.7.2.16 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.
6.7.2.17 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.
6.7.2.18 F23: Sleep mode switching time
When the welding power source is not operated for a fixed period of time, it can be turned into the sleep
mode.
•
[0]: disables the function.
•
[1] to [10]: enables the function.
Set the transition time to the sleep mode in the range of 1 to 10. During the sleep mode, power
consumption is reduced.
–
In the sleep mode, the dot at the first digit on the
left/right digital meters flashes. All the other
displays on the operation panel are turned OFF.
–
Any operation during the sleep mode restores the
condition to the previous state.
