AIR VANTAGE ® 500(AU) KUBOTA
A-6
REMOTE CONTROL
The AIR VANTAGE ® 500(AU) KUBOTA is equipped
with a 6-pin and a 14-pin connector. The 6-pin con-
nector is for connecting the K857 or K857-1 Remote
Control or for TIG welding, the K870 foot Amptrol or
the K963-3 hand Amptrol. When in the CC-STICK,
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 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 max-
imum 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 40-200 amps, rather than the
full 40-300 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
The auxiliary power capacity of the AIR VANTAGE®
500(AU) KUBOTA is 7.2KW of 60Hz single phase
power protected by an RCD (Residual Current
Device) and 2 single phase 15 amp circuit breakers.
The auxiliary power capacity in watts equivalent to
volt-amperes at unity power factor.
This model has:
1 Residual Current Device (RCD) protection (30mA).
2 x 1 phase 15 amp Circuit Breakers.
2 x 1 phase 240 volt 15 amp per outlet.
Note: The single-phase outlets are from different
phases and cannot be paralleled.
The auxiliary power receptacles should only be used
with three grounded type plugs or approved double
insulated tools. The current rating of any plug used
with the system must be at least equal to the current
capacity of the associated receptacle.
STANDBY POWER CONNECTIONS
The AIR VANTAGE® 500(AU) KUBOTA is suitable for
temporary, standby or emergency power using the
engine manufacturerʼs recommended maintenance
schedule.
The AIR VANTAGE® 500(AU) KUBOTA can be per-
manently installed as a standby power unit for 240 volt
(60Hz). Connections must be made by a licensed
electrician who can determine how the 240 VAC
power can be adapted to the particular installation and
comply with all applicable electrical codes. The follow-
ing information can be used as a guide by the electri-
cian for most applications.
1 Install an isolation switch between the power com-
pany meter and the premises disconnect. (The AIR
VANTAGE® 500(AU) KUBOTA and the power
company supplies must not be connected togeth-
er).
Switch rating must be the same or greater than the
customerʼs premises disconnect and service over cur-
rent protection.
2. Take necessary steps to assure load is limited to
the capacity of the AIR VANTAGE® 500(AU)
KUBOTA. Loading above the rated output will
reduce output voltage below the allowable -10% of
rated voltage which may damage appliances or
other motor-driven equipment and may result in
overheating of the AIR VANTAGE® 500(AU) KUB-
OTA engine.
