VRD - Voltage Reduction Device - everywhere you weld
RAINBOW 183 cell VRD unit is standard fitted with a Voltage Reduction Device to reduce the maximum open-circuit voltage at the output terminals to less than 15 V as long as the arc starts and the selected welding current becomes fully available.
On the contrary, immediately at the end of the welding operation, the power source voltage goes back to a safe level till next welding cycle reoccurs.
RAINBOW 183 cell VRD always provides the users with an additional safety protection when working in all highly hazardous environments such as damp, caustic, salty and wet places.
This machine is fully compliant with strict Australian Standards AS16742.-2003 imposed for welding machines used in any place classified as dangerous. All such features make RAINBOW 183 cell VRD ideal for use in mining industry and onsite works.
The voltage monitoring LED changes colour depending on circumstances, i.e.
- GREEN: whenever voltage is less than 35V both while welding or in open circuit condition.
- RED: whenever voltage is more than 35V while welding, depending on the real arc voltage.
