GENERAL DESCRIPTION
The AIR VANTAGE ® 650 CUMMINS is a diesel engine-
driven welding power source. The machine uses a
brush type alternating current generator for DC multi-
purpose welding, for 240 VAC single phase. The AIR
VANTAGE
® 650 CUMMINS also has a rotary screw 60
cfm air compressor built in. The DC welding control sys-
tem uses state of the art Chopper Technology for
superior welding performance.
The AIR VANTAGE ® 650 CUMMINS is fitted with a
selectable VRD(Voltage Reduction Device). The VRD
operates in the CC-Stick mode reducing the OCV to
<13 volts, increasing operator safety when welding is
performed in environments with increased hazard of
electric shock such as wet areas and hot, humid
sweaty conditions.
WARNING
FOR AUXILIARY POWER:
Start the engine and set the IDLER control switch to
the desired operating mode. Full power is available
regardless of the welding control settings providing no
welding current is being drawn.
