VOLTAGE REDUCTION DEVICE (VRD)

The voltage reducing device (or VRD) reduces the no-load voltage allocated to a level not exceeding 35 V when the resistance of
the external welding circuit exceeds 200 Ω. The reaction time is less than 300 ms. By default, the reducing device is disabled. In
order to enable it, the user must open the product and follow the following procedure :
- Unplug the product from the mains and wait 5 minutes for safety.
- Remove the 3 screws from each handle support (1 on top and 2 on the side) = 4x3 screws.
- Remove the 4 handle holders and the 2 tubes.
- Remove the 2 remaining centre screws from the cover.
- Carefully remove the cover and disconnect the ground wire connected under the case.
- Locate the control board and the red switch (see page 82).
- Toggle switches 1 and 2 (default ON position) to the opposite position.
- Put the unit back together.
- Switch on the product, the device is active and the «VRD» LED on the keypad lights up.

CAUSES
Wait for the indicator to turn off before resuming
welding operations.
Oserve the duty cycle and insure a good ventilation.
Using the optional anti dust filter will reduce the duty
cycle.
Have your electrical installation checked by a quali-
fied person. The voltage between the phases must be
between 340V RMS and 460V RMS.
Have the sensor's connection cables checked by a
qualified person.
Have the relay's command connection cables checked
by a qualified person.
