24. VRD Function (Voltage reduction Device)
The VRD function is only used in the welding process ELECTRODE.
"Voltage Reduction Device" (VRD) is a protection device, to set the open-circuit voltage lower than 13V.
It prevents the formation of voltages at the output terminals, which can be dangerous for people. As standard
this feature is disabled, and is not required for normal welding operation.
Two-colour display LED VRD:
OFF:
VRD not active
Green:
VRD active, voltage OK
Red:
VRD active, machine is in weld mode and the VRD protection is deactivated
