Voltage Reduction Device VRD

The VRD function fulfils the purpose of drastically reducing the harm which may result to a person from inadvertent contact with the electrode during non-welding pauses.

The VRD automatically switches the control mode in CV and sets the voltage to a safe value (typically <13V) each time the

welding process is interrupted for a period longer than 3 sec.

The VRD function is active only in CC mode.
