REMOTE CONTROL
OUTPUT
The Vantage is equipped with a 6-pin and a 14-pin connector. The
6-pin connector is for connecting the K857 or K857-1 Remote
Control or for TIG welding, the K870 foot Amptrol or the K936-2
hand Amptrol. When in the CC-STICK, DOWNHILL PIPE, 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.
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 connector, the auto-sensing circuit
automatically makes the Output Control inactive and the wire
feeder voltage control active
NOTE: When a wire feeder with a built in welding voltage
control is connected to the 14-pin connector, do not connect
anything to the 6-pin connector.

AUXILIARY POWER RECEPTACLES
The auxiliary power capacity of the Vantage is 12,000 watts of 60
Hz, single phase power or 20,000 watts of 60Hz, three phase
power. The auxiliary power capacity rating in watts is equivalent
to volt-amperes at unity power factor. The maximum permissible
current of the 240 VAC single phase output is 50 A. The 240 VAC
output can be split to provide two separate 120 VAC outputs with
a maximum permissible current of 50 A per output to two separate
120 VAC branch circuits. The output voltage is within ± 10% at
all loads up to rated capacity.
The Vantage has two 20 Amp-120VAC single phase (5-20R)
GFCI duplex receptacles and one 50 Amp-120/240 VAC single
phase (14-50R) receptacle and one 240VAC three phase (15-
50R) receptacle. The 120/240 VAC receptacle can be split for
single phase 120 VAC operation. The 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 receptacle.
NOTE: The two 120V GFCI receptacles and the two 120 volt
circuits of the 120/240V receptacle are connected to different
phases and can not be paralleled.
STANDBY POWER CONNECTIONS
The Vantage is suitable for temporary, standby or emergency
power using the engine manufacturer’s recommended
maintenance schedule.
The Vantage can be permanently installed as a standby power
unit for 240 volt-3 wire, 50 amp service. Connections must be
made by a licensed electrician who can determine how the
120/240 VAC power can be adapted to the particular installation
and comply with all applicable electrical codes. The following
information can be used as a guide by the electrician for most
applications. Refer to the connection diagram shown in Figure
A.2.
1. Install the double-pole, double-throw switch between the power
company meter and the premises disconnect.
Switch rating must be the same or greater than the customer’s
premises disconnect and service over current protection.
