GENERAL DESCRIPTION

The VANTAGE® 400 is a diesel engine powered DC
multi-process welding power source and 120 / 240 volt
AC power generator. The engine drives a generator
that supplies three phase power for the DC welding cir-
cuit, single phase and Three Phase power for the AC
auxiliary outlets. The DC welding control system uses
state of the art Chopper Technology (CT ™ ) for superi-
or welding performance.
The Vantage® 400 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.

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.
