4. ARC CONTROL
-
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) increases
the short circuit current which results in a more forceful dig-
ging arc. Typically a forceful digging arc is preferred for root
and hot passes. A softer arc is preferred for fill and cap pass-
es 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 proce-
dure and operator preference. Start with a setting of 0.
5. WELD OUTPUT TERMINALS WITH FLANGE
NUT-
Provides a connection point for the electrode and
work cables.
6. GROUND STUD-
Provides a connection point for
connecting the machine case to earth ground.
7. 14-PIN CONNECTOR-
For attaching wire feeder control
cables. Includes contactor closure circuit, auto-sensing
remote control circuit, and 42V power. The remote control
circuit operates the same as the 6 Pin Amphenol.
8. 6-PIN CONNECTOR-
For attaching optional remote con-
trol equipment. Includes auto-sensing remote control circuit.
9. WELD TERMINALS CONTROL SWITCH-
In the
WELD TERMINALS ON position, the output is electrically hot
all the time. In the REMOTELY CONTROLLED position, the
output is controlled by a wire feeder or amptrol device, and is
electrically off until a remote switch is depressed.
10. WIRE FEEDER VOLTMETER SWITCH:
Matches the polarity of the wire feeder voltmeter to the
polarity of the electrode.
11. VRD (Voltage Reduction Device) INDICATOR
LIGHTS-
On the front panel of the VANTAGE 400 (CE)
are two indicator lights. A red light when lit indicates
OCV(Open Circuit Voltage) is equal to or
greater than
(32V ), (30V ) and a green light when lit indicates
OCV(Open Circuit Voltage)
is less than (32V ), (30V ).
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 the CC-Stick mode when not welding
the green light will illuminate indicating that the VRD has
reduced the OCV to less than (32V ), (30V ). During weld-
ing the red light will illuminate whenever the arc voltage is
equal to or greater than (32V ), (30V ). This means that the
red and green light may alternate depending on the weld
voltage. This is normal operation.
If the red light remains illuminated when not welding in the
CC-stick mode, 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.
