Matweld | Welder Inverter 200A 220V VRD

200A 220V VRD Inverter Welder
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
Compact and lightweight
Stable Arc with excellent striking capabilities
Hot Start MMA
Over Voltage and Over Current protection
Suitable for Scratch Start TIG welding
Supplied with welding cables
