AIR VANTAGE
®
800 (AU) CUMMINS
The AIR VANTAGE
®
800 (AU) CUMMINS is shipped with the
negative battery cable disconnected. Before you operate the
machine, make sure the Engine Switch is in the OFF position and
attach the disconnected cable securely to the negative (-) battery
terminal.
Remove the insulating cap from the negative battery terminal.
Replace and tighten negative battery cable terminal. NOTE: This
machine is furnished with a wet charged battery; if unused for
several months, the battery may require a booster charge. Be sure
to use the correct polarity when charging the battery.
MUFFLER OUTLET PIPE
Remove the plastic plug covering the muffler outlet tube. Using
the clamp provided secure the outlet pipe to the outlet tube with
the pipe positioned such that it will direct the exhaust in the
desired position.
SPARK ARRESTOR
Some federal, state or local laws may require that petrol or diesel
engines be equipped with exhaust spark arrestors when they are
operated in certain locations where unarrested sparks may
present a fire hazard. The standard muffler included with this
welder has an internal spark arrestor. When required by local
regulations, a suitable spark arrestor, must be installed and
properly maintained.
CAUTION
An incorrect arrestor may lead to damage to the engine or
adversely affect performance.
AIR CLEANER INLET HOOD
Remove the plastic plug covering the air cleaner inlet. Install the
air cleaner inlet hood to the air cleaner.
WELDING TERMINALS
The AIR VANTAGE
®
800 (AU) CUMMINS is equipped with a toggle
switch for selecting "hot" welding terminals when in the "WELD
TERMINALS ON" position or "cold" welding terminals when in the
"REMOTELY CONTROLLED" position.
WELDING OUTPUT CABLES
With the engine off, route the electrode and work cables thru the
strain relief bracket provided on the front of the base and connect
to the terminals provided. These connections should be checked
periodically and tightened if necessary.
Listed in Table A.1 are copper cable sizes recommended for the
rated current and duty cycle. Lengths stipulated are the distance
from the welder to work and back to the welder again. Cable sizes
are increased for greater lengths primarily for the purpose of
minimizing cable voltage drop.

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:
WARNING
•
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 securely connected to the metal 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 codes.
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 ground stake going into the ground for at least 10
Feet or to the metal framework of a building which has been
effectively grounded.
The National Electric Code lists a number of alternate means of
grounding electrical equipment. A machine grounding stud
