This will keep the "Solid State" contactor open and provide a
"cold" electrode until the Amptrol or Arc Start Switch is pressed.
When using the TIG Module, the OUTPUT CONTROL on the
VANTAGE® 400 (AU) is used to set the maximum range of the
CURRENT CONTROL on the TIG Module or an Amptrol if con-
nected 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 oper-
ation, see table B.1.
WIRE WELDING-CV
Connect a wire feeder to the VANTAGE® 400 (AU) according
to the instructions in INSTALLATION INSTRUCTIONS Section.
The VANTAGE® 400 (AU) 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 prefer-
ence. 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.

ARC GOUGING
The VANTAGE® 400 (AU) can be used for arc gouging. For
optimal performance, set the MODE switch to ARC GOUGING.
Set the OUTPUT CONTROL knob to adjust output current to
the desired level for the gouging electrode being used accord-
ing to the ratings in the following Table B.4.
Carbon Diameter
1/8" (3.2mm)
5/32" (4.0mm)
3/16" (4.8mm)
1/4" (6.4mm)
The ARC CONTROL is not active in the ARC GOUGING Mode.
The ARC CONTROL is automatically set to maximum when the
ARC GOUGING mode is selected which provides the best ARC
GOUGING performance.
Note: With the VRD switch in the "ON" position there is no out-
put in the Arc Gouging Mode. For indicator light operation, see
table B.1.
AUXILIARY POWER:
Start the engine and set the IDLER control switch to the desired
operating mode. Full power is available regardless of the weld-
ing 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 Table
B.5.
