F19: Setting the switching off of the alarm
If an alarm is issued, the welding power source’s current output can be interrupted. For some alarm codes,
it is possible to continue welding even if an alarm is detected. This can cause an alarm signal to be ignored.
This function can be used to force a stop.
When resetting alarms, the device behaves the same as when resetting faults.
10.2 Faults on the control panel on page EN
F20: Setting the lower threshold value of the mains voltage monitoring
Defines the threshold value from which a primary mains voltage is detected. If the mains voltage falls below
this value, an error message is issued. The specified mains voltage of the welding power source is between
340 V and 460 V. If the mains voltage falls below this value, it can have a profound negative impact on the
performance of the welding power source.
F21: Activating the maximum capacity of the cooling fan
The speed of the fan motor and thus the cooling capacity is controlled depending on the temperature
measured in the power source. This Eco mode saves energy and prevents unnecessary foreign particles from
entering the device. This function allows the cooling fan to run at maximum speed during the entire
operation.
F22: Deactivating the button tones
Deactivates the sounds when the user presses a button on the control panel.
F23: Setting the time period until stand-by mode
If the device is not used for a longer period of time, it can be automatically switched to stand-by mode. Power
consumption is reduced. When in stand-by mode, a dot blinks in both digital displays. All other displays and
operations are switched OFF. Any operation terminates stand-by mode and the device returns to normal
mode.
