WIRE WELDING-CV
Connect a wire feeder to the AIR VANTAGE ® 700
(AU) CUMMINS according to the instructions in
INSTALLATION INSTRUCTIONS Section.
The AIR VANTAGE ® 700 (AU) CUMMINS in the CV-
WIRE mode, permits it to be used with a broad range
of flux cored wire (Innershield and Outershield) elec-
trodes 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.
ARC GOuGING
The AIR VANTAGE ® 700 (AU) CUMMINS 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 perfor-
mance, set the MODE per Table b.4.
The maximum output control range setting is automat-
ically increased in the gouging mode, when the com-
pressor is not turned on. The maximum preset read-
out on the weld ammeter will increase from approxi-
mately 700 Amps to 800 Amps. This feature provides
extra capacity by taking advantage of the available
engine HP when the internal compressor is not on and
an external air supply is used for gouging.
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
The ARC CONTROL is not active in the ARC GOUG-
ING Mode. The ARC CONTROL is automatically set
to maximum when the ARC GOUGING mode is
selected which provides the best ARC GOUGING per-
formance.

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.
