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.
AUXILIARY POWER OPERATION
If a GFCI receptacle is tripped, See the MAINTE-
NANCE section for detailed information on testing and
resetting the GFCI receptacle.
Start the engine and set the IDLER control switch to
the desired operating mode. Full power is available
regardless of the welding control settings, if no weld-
ing current is being drawn.
The auxiliary power of the AIR VANTAGE® 500 con-
sists of two 20 Amp-120VAC single phase (5-20R)
GFCI duplex receptacles, one 50 Amp-120/240VAC
single phase (14-50R) receptacle and one 50 Amp
240VAC three phase (15-50R) receptacle. The
120/240VAC receptacle can be split for single phase
120 VAC operation.
The auxiliary power capacity is 12,000 watts of 60 Hz,
single phase power or 20,000 watts of 60Hz, three
phase power.

AIR VANTAGE® 500 CUMMINS
The auxiliary power capacity rating in watts is equiva-
lent to volt-amperes at unity power factor. The maxi-
mum permissible current of the 240 VAC output is 50
A. The 240 VAC single phase output can be split to
provide two separate 120 VAC outputs with a maxi-
mum permissible current of 50 A per output to two
separate 120 VAC branch circuits. Output voltage is
within ± 10% at all loads up to rated capacity.
NOTE: The two 120V GFCI receptacles and the two
120V circuits of the 120/240V receptacle are connect-
ed to different phases and cannot be paralleled.
The auxiliary power receptacles should only be used
with three wire grounded type plugs or approved dou-
ble insulated tools with two wire plugs.
The current rating of any plug used with the system
must be at least equal to the current capacity of the
associated receptacle.
SIMULTANEOUS WELDING AND AUXIL-
IARY POWER LOADS
It must be noted that the above auxiliary power ratings
are with no welding load.
Simultaneous welding and power loads are specified
in table B.4.
