SPARK ARRESTOR
The muffler included with this welder has been modi- fied and now qualifies as a spark arrestor. Mufflers on
WARNING
• Spark Arrestor and Muffler may be hot!
Allow engine to cool before servicing spark arrestor!
Do not operate engine while servicing spark arrestor!
machines manufactured before this change do not qualify as spark arrestors and were shipped from the factory with an additional spark arresting unit for that purpose. Integral spark arresting mufflers will have a clean out service plug and will have “USDA FS 51001C QUALIFIED SPARK ARRESTOR” stamped on the muffler shell. Any spark arrestor must be serviced and properly maintained. For machines with separate spark arrestors, secure the arrestor to the outlet tube on the muffler using the clamp provided.
An incorrect spark arrester may lead to damage to the engine or adversely affect performance.
CAUTION
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 mini- mizing 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 insulated 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 provided on the welding generator frame foot.
