MATWELD WELDER INVERT 200A 220V VRD
VRD stands for Voltage Reduction Device
A VRD reduces the maximum open circuit voltage across the output
terminals to below 15 volts
This is a safety requirement of most mines in South Africa when the
unit is to be operated underground or in damp conditions. The presence
of a VRD can however cause difficulty in the striking and re-striking of
the arc with less skilled operators. This is because the machine has to
rapidly change from the reduced open circuit voltage of below 15 volts
to the open circuit voltage of around 56 volts necessary to strike the
arc.
