DUAL VANTAGE ® 700 (AU)

WIRE WELDING-CV

Connect a wire feeder to the DUAL VANTAGE
according to the instructions in INSTALLATION
INSTRUCTIONS Section.
The DUAL VANTAGE
®
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 weld-
ing). Welding can be finely tuned using the ARC CON-
TROL. 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 induc-
tance/pinch control. The proper setting depends on
the procedure and operator preference. Start with the
dial set at 0.

ARC GOUGING

The DUAL VANTAGE 700 (AU) can be used for arc
®
gouging. The minimum output in the arc gouging
mode is 200 Amps. For arc gouging below 200 Amps
use the CC-Stick Mode. For optimal performance, set
the MODE per Table B.4.
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.
TABLE B.4
Carbon Diameter Current Range (DC,
electrode positive)
1/8"(3.2mm) 60-90 Amps
5/32"(4.0mm) 90-150 Amps
200-250 Amps
3/16"9(4.8mm)
300-400 Amps
1/4"(6.4mm)
3/8"(10.0mm) 400-600 Amps
1/2"(13.0mm) 600-MAX. Amps
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.

PARALLELING

When paralleling machines in order to combine their
outputs, all units must be operated in the CC-STICK
mode only at the same output settings. To achieve
this, turn the WELD MODE switch to the CC-STICK
position. Operation in other modes may produce errat-
ic outputs, and large output imbalances between the
units.
