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.
