DC Inverters

DC INVERTER WELDER Single Phase 220V DC Inverters MMA / TIG Compact and lightweight Stable Arc with excellent striking capabilities Hot Start MMA Over Voltage and Over Current protection Carry Handle and Convenient Shoulder strap Suitable for Scratch Start TIG welding Supplied with welding cables 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 vol tage of below 15 volts to the open circuit voltage of around 56 volts necessary to strike the arc Technical data         ARC160 MAT9050VRD Input Power Voltage               Single Phs AC220V’b110% Rated Input Power Capacity            5.3 KVA No Load Voltage                  9V Output Current Range            20-155A Rated Output Voltage               26.2 Duty Cycle 10%                  60% Weight                   8Kg Dimensions (LWH)                  371 x 155 x 295mm
