- The ARC CONTROL dial is active in
the CV-WIRE, CC-STICK and DOWNHILL PIPE modes, and
has different functions in these modes. This control is not
active in the TIG and ARC GOUGING mode.
CC-stICK mode: In this mode, the ARC CONTROL dial sets
the short circuit current (arc-force) during stick welding to
adjust for a soft or crisp arc. Increasing the dial from –10
(soft) to +10 (crisp) increases the short circuit current and
prevents sticking of the electrode to the plate while welding.
This can also increase spatter. It is recommended that the
ARC CONTROL be set to the minimum number without elec-
trode sticking. Start with a setting at 0.
DOWNHILL PIPe mode: In this mode, the ARC CONTROL
dial sets the short circuit current (arc-force) during stick weld-
ing to adjust for a soft or a more forceful digging arc (crisp).
Increasing the number from –10 (soft) to +10 (crisp) increas-
es the short circuit current which results in a more forceful
digging arc. Typically a forceful digging arc is preferred for
root and hot passes. A softer arc is preferred for fill and cap
passes where weld puddle control and deposition ("stacking"
of iron) are key to fast travel speeds. It is recommended that
the ARC CONTROL be set initially at 0.
CV-WIRe mode: In this mode, turning the ARC CONTROL
clock wise from –10 (soft) to +10 (crisp) changes the arc from
soft and washed-in to crisp and narrow. It acts as an induc-
tance/pinch control. The proper setting depends on the pro-
cedure and operator preference. Start with a setting of 0.

11. VRD (Voltage Reduction Device) INDICatOR
LIGHts -
On the front panel of the VANTAGE® 400 (AU)
are two indicator lights. A red light when lit indicates
OCV(Open Circuit Voltage) is equal to or
and a green light when lit indicates OCV(Open Circuit
is less than 30V.
Voltage)
The VRD "On/Off" switch inside the control panel must be
"On" for the VRD function to be active and the lights to be
enabled. When the machine is first started with VRD
enabled, both lights will illuminate for 5 seconds.
These lights monitor the OCV(Open Circuit Voltage) and
weld voltage at all times. In all modes when not welding the
green light will illuminate indicating that the VRD has
reduced the OCV to less than 30V. During welding the red
light will illuminate whenever the arc voltage is equal to or
greater than 30V. This means that the red and green light
may alternate depending on the weld voltage. This is nor-
mal operation.
If the red light remains illuminated when not welding, the
VRD is not functioning properly. Please refer to your local
field service shop for service.
If the VRD is turned "On" and the lights don't come "On",
refer to the trouble shooting section.
