A-6
REMOTE CONTROL
The AIR VANTAGE® 500 KUBOTA is equipped with a
6-pin and a 14-pin connector. When in the ARC
GOUGING or CV-WIRE modes and when a remote
control is connected to the 6-pin Connector, the auto-
sensing circuit automatically switches the OUTPUT
control from control at the welder to remote control.
When in TOUCH START TIG mode and when a
Amptrol is connected to the 6-Pin Connector, the
OUTPUT dial is used to set the maximum current
range of the CURRENT CONTROL of the Amptrol.
When in the CC-STICK or DOWNHILL PIPE mode
and when a remote control is connected to the 6-Pin
or 14-Pin connector, the output control is used to set
the maximum current range of the remote.
EXAMPLE: When the OUTPUT CONTROL on the
welder is set to 200 amps the current range on the
remote control will be min.-200 amps, rather than the
full min.-max. amps. Any current range that is less
than the full range provides finer current resolution for
more fine tuning of the output.
In the CV-WIRE mode, if the feeder being used has a
voltage control when the wire feeder control cable is
connected to the 14-Pin Connector, the auto-sensing
circuit automatically makes OUTPUT CONTROL inac-
tive and the wire feeder voltage control active.
Otherwise, the OUTPUT CONTROL is used to preset
the voltage.
The 14-pin connector is used to directly connect a
wire feeder control cable. In the CV-WIRE mode,
when the control cable is connected to the 14-pin con-
nector, the auto-sensing circuit automatically makes
the Output Control inactive and the wire feeder volt-
age control active.
NOTE: When a wire feeder with a built in welding
voltage control is connected to the 14-pin connec-
tor, do not connect anything to the 6-pin connec-
tor.

AuXILIARY POWER RECEPTACLES
Start the engine and set the “IDLER” control switch to the
“High Idle” mode. Voltage is now correct at the recepta-
cles for auxiliary power. This must be done before a
tripped GFCI can be reset properly. See the MAINTE-
NANCE section for more detailed information on testing
and resetting the GFCI.
The auxiliary power of the AIR VANTAGE® 500 KUBO-
TA consists of two 20 Amp-120 VAC (5-20R) duplex
receptacles with GFCI protection, one 50 Amp 120/240
VAC (14-50R) receptacle and one 50 Amp 240VAC
Three-Phase (15-50R) receptacle.
The auxiliary power capacity is 13,000 watts Peak,
12,000 Watts Continuous of 60 Hz, single phase power.
The auxiliary power capacity rating in watts is equivalent
to volt-amperes at unity power factor. The max permissi-
ble current of the 240 VAC output is 50amps.
The 240 VAC output can be split to provide two separate
120 VAC outputs with a max permissible current of 50
Amps per output to two separate 120 VAC branch cir-
cuits (these circuits cannot be paralleled). Output voltage
is within ± 10% at all loads up to rated capacity.
The Three-Phases auxiliary power capacity is 22,000
watts peak, 20,000 watts continuous. The maximum cur-
rent is 45 amps.
120 V DuPLEX RECEPTACLES AND GFCI
A GFCI protects the two 120V auxiliary power
receptacles.
A GFCI (Ground Fault Circuit Interrupter) is a device to
protect against electric shock should a piece of defective
equipment connected to it develop a ground fault. If this
situation should occur, the GFCI will trip, removing volt-
age from the output of the receptacle. If a GFCI is tripped
see the MAINTENANCE section for detailed information
on testing and resetting it. A GFCI should be properly
tested at least once every month.
The 120 V auxiliary power receptacles should only be
used with three wire grounded type plugs or approved
double 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 recepta-
cle.
NOTE: The 240 V receptacle has two 120 V circuits, but
are of opposite polarities and cannot be paralleled.
All auxiliary power is protected by circuit breakers. The
120V has 20 Amp circuit breakers for each duplex recep-
tacle. The 120/240V Single Phase and the 240V Three-
Phases have a 50 Amp 3-pole Circuit Breaker that dis-
connects both hot leads and all Three Phases simultane-
ously.
