ACTIVATION OF THE VRD FUNCTION (VOLTAGE REDUCTION DEVICE)
The voltage reduction device (or VRD) is used to protect the welder. The welding current is only delivered when the electrode is in contact with the
workpiece (low resistance). As soon as the electrode is removed, the VRD function lowers the voltage considerably.
By default, the voltage reduction device is deactivated. In order to activate it, the user must open the product and complete the following proce-
dure:
1. DISCONNECT THE PRODUCT FROM THE POWER SUPPLY AND WAIT 5 MINUTES FOR SAFETY.
2. Remove the side of the power source (see page at the end of the manual).
3. Locate the control board and the VRD switch (see page at the end of the manual).
4. Toggle the switch to the ON position.
5. The VRD function is activated.
6. Reinstall the side panel of the unit.
7. The VRD icon on the interface (HMI) will be lit.
To deactivate the VRD function, simply flip the switch back to the opposite position.

CAUSES
Wait for the light to go out before resuming welding.
Respect the duty cycle and ensure good ventilation.
Use of the optional dust filter reduces the duty cycle.
Have your electrical installation checked by a quali-
fied electrician. The voltage between phases must be
between 185Veff and 600Veff.
Have the wiring of the primary connector checked by
qualified personnel.
Have the relay control wiring checked by qualified
personnel.
