VANTAGE
322 / LE400
®
reMote control
The Vantage
322 / LE400 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.
The 14-pin connector is used to directly connect a wire feeder
control cable. 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 inactive and the wire feeder voltage
control active. Otherwise, the OUTPUT CONTROL is used to preset
the voltage.
WARNING
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.

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.)
WARNING
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.
•
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 connected 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 instructions in the section entitled "Standby
Power Connections" as well as the article on grounding in the
latest National Electrical Code and the local code.
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 alternate 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
322 / LE400 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 dictates the polarity of the
electrode cable. These connections 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.
