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.
Simultaneous Welding and Auxiliary Power Loads
The auxiliary power ratings are with no welding load.
Simultaneous welding and power loads are specified in

ARC GOUGING
The VANTAGE® 400 can be used for arc gouging. For opti-
mal performance, set the MODE switch to CC-STICK and the
ARC CONTROL to +10.
Set the OUTPUT CONTROL knob to adjust output current to
the desired level for the gouging electrode being used
according to the ratings in the following Table B.4.
• Set the "WELDING TERMINALS" switch to the
"REMOTELY CONTROLLED" position. This will keep the
"Solid State" contactor open and provide a "cold" elec-
trode until the Amptrol or Arc Start Switch is pressed.
When using the TIG Module, the OUTPUT CONTROL on the
VANTAGE® 400 is used to set the maximum range of the
CURRENT CONTROL on the TIG Module or an Amptrol if
connected to the TIG Module.
NOTE: The TIG process is to receive a low voltage welding
process. There is no difference in operation with the
VRD “On” or “Off” for this mode. For indicator light
operation, see Table B.1.
WIRE WELDING-CV
Connect a wire feeder to the VANTAGE® 400 according to
the instructions in INSTALLATION INSTRUCTIONS Section.
The VANTAGE® 400 in the CV-WIRE mode, permits it to be
used with a broad range of flux cored wire (Innershield and
Outershield) electrodes and solid wires for MIG welding (gas
metal arc welding). Welding can be finely tuned using the
ARC CONTROL. Turning the ARC CONTROL clockwise
from –10 (soft) to +10 (crisp) changes the arc from soft and
washed-in to crisp and narrow. It acts as an inductance/pinch
control. The proper setting depends on the procedure and
operator preference. Start with the dial set at 0.
NOTE: In the CV-Mode with VRD “On”, the OCV(Open
Circuit Voltage) is not reduced. For indicator light
operation, see Table B.1.
