SPARK ARRESTOR
WARNING
WARNING
• Spark Arrestor and Muffler may be hot!
Allow engine to cool before servicing spark arrestor! 
Do not operate engine while servicing spark arrestor!
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. The welder was shipped from the factory with a sepa- rate spark arresting unit. If a spark arrestor is required secure the spark arrestor to the outlet tube of the muf- fler using the clamp provided. Any spark arrestor must be serviced and properly maintained.
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 connections should be checked periodically and tightened if neces- sary.
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.

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,
or
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 
symbol is provid- ed on the welding generator frame foot.
