SPARK ARRESTOR
WARNING
Some federal, state or local laws may require that
diesel engines be equipped with exhaust spark
arrestors when they are operated in certain locations
where unarrested sparks may present a fire hazard.
CAUTION
An incorrect spark arrester may lead to damage to
the engine or adversely affect performance.

WELDING OUTPUT CABLES
With the engine off, connect the electrode and
work cables to the studs provided. These connec-
tions should be checked periodically and tightened
if necessary.
Listed in Table A.1 are copper cable sizes recom-
mended 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.

EXHAUST OUTLET PIPE
Remove cap from DOC pipe protruding from roof.
Using the clamp & seal provided, secure the outlet
pipe to the outlet tube with the pipe positioned
such that it will direct the exhaust in the desired
direction. Tighten using a 1/4" (6mm) internal sock-
et or allen wrench. Torque to 106 in-lbs (9 ft-lbs)

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
powered by this engine driven welder must:
a) be grounded to the frame of the welder using a
grounded type plug,
b) be double insulated.
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 con-
nected to premises wiring such as that in a home or
shop, its frame must be connected to the system earth
ground. See the article on grounding in the latest U.S.
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 insulat-
ed joints, or to the metal framework of a building
which has been effectively grounded. The U.S.
National Electrical Code lists a number of alternate
means of grounding electrical equipment. A machine
grounding stud marked with the
ed on the welding generator frame foot.
