VRD stands for Voltage reduction device. By reducing the maximum unloaded open circuit voltage across the output terminals, the WELDSAFE VRD will reduce the maximum unloaded open circuit voltage across the output terminals of the welding machine to a safe voltage. This reduced voltage is about 12 volts (Australian Standards 1674.2 2003 state this voltage must be less than 35 Volts DC and 25 Volts AC).
Only when a load of less than 200 ohms resistance is applied to the output wil the WELDSAFE VRD turn the welding machine to full output so that welding will commence.
The WELDSAFE VRD will only turn the output of the welder back to a reduced output state of 12 volts once the electrode is removed from the workpiece or if the resistance across the output rises above 200 ohms.
IN SHORT..... SAFE WORK PRACTICES SAVE LIVES.
Why is a WELDSAFE VRD so important?
Although most new , welding machines have an open circuit voltage that meets the legal requirements (105 volts DC or 85 volts AC) this can only be considered safe in dry conditions.
However if used in non-normal conditions (damp or wet, caustic, salty or in a confined place) recieving an electric shock has proven to cause serious injury to the operator and has even proven to be fatal.
