ACTIVATION OF THE VRD FUNCTION (VOLTAGE REDUCTION DEVICE)
This device protects the welder. The welding current is delivered only when the electrode is in contact with the part (low
resistance). As soon as the electrode is removed, the VRD function lowers the voltage to a very low value.
The VRD function is originally disabled. However, this can be activated by means of an ON/OFF switch on the power
source control board. To access it, follow the steps below:
1. DISCONNECT THE PRODUCT FROM THE POWER SUPPLY BEFORE HANDLING.
2. Remove the screws to take the power source cover off.
3. Locate the switch on the control board (red box on diagram below - n° 2).
4. Turn the switch located on this control card ON. The red LED switches off.
5. The VRD function is activated.
6. Screw the power source cover back on.
7. On the interface (HMI), the LED for the VRD function is lighted :
To deactivate the VRD function, simply turn the switch located on the control board back to OFF. The VRD LED on the
