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 connector, do not con-
nect anything to the 6-pin connector.

ELECTRICAL CONNECTIONS
MACHINE GROUNDING
Because this portable engine driven welder creates its
own power, it is not necessary to connect its frame to
an earth ground, unless the machine is connected to
premises wiring (home, shop, etc.)
To prevent dangerous electric shock, other equipment
to which this engine driven welder supplies power
must:
• Be grounded to the frame of the welder using a
grounded type plug or be double insulated.
• Do not ground the machine to a pipe that carries
explosive or combustible material.
------------------------------------------------------------------------
When this welder is mounted on a truck or trailer, its
frame must be electrically bonded to the metal frame
of the vehicle. Use a #8 or larger copper wire connect-
ed between the machine grounding stud and the
frame of the vehicle. When this engine driven welder
is connected to premises wiring such as that in a
home or shop, its frame must be connected to the
system earth ground. See further connection instruc-
tions in the section entitled "Standby Power
Connections" as well as the article on grounding in the
latest National Electrical Code and the local code.
WARNING
WARNING
In general, if the machine is to be grounded, it should
be connected with a #8 or larger copper wire to a solid
earth ground such as a metal water pipe going into the
ground for at least ten feet and having no insulated
joints, or to the metal framework of a building which
has been effectively grounded.
The National Electrical Code lists a number of alter-
nate means of grounding electrical equipment. A
machine grounding stud marked with the symbol
is provided on the front of the welder.
WELDING TERMINALS
The VANTAGE 400 is equipped with a toggle switch
for selecting "hot" welding terminal when in the "WELD
TERMINALS ON" position or "cold" welding terminal
when in the "REMOTELY CONTROLLED" position.
WELDING OUTPUT CABLES
With the engine off connect the electrode and work
cables to the output studs. The welding process dic-
tates the polarity of the electrode cable. These con-
nections should be checked periodically and tightened
with a 3/4" wrench.
Table A.1 lists recommended cable sizes and lengths
for rated current and duty cycle. Length refers to the
distance from the welder to the work and back to the
welder. Cable diameters are increased for long cable
lengths to reduce voltage drops.
TABLE A.1
CABLE INSTALLATION
Install the welding cables to your VANTAGE 400 as
follows.
1. The engine must be OFF to install welding cables.
2. Remove the flanged nuts from the output terminals
3. Connect the electrode holder and work cables to
the weld output terminals. The terminals are identi-
fied on the case front.
4. Tighten the flanged nuts securely.
5. Be certain that the metal piece you are welding (the
“work”) is properly connected to the work clamp and
cable.
