SPARK ARRESTER

WARNING
• Spark Arrester and Muffler may be hot!
• Allow engine to cool before servicing
spark arrester!
• Do not operate engine while servicing
spark arrester!
Some federal, state or local laws may require that gasoline or
diesel engines be equipped with exhaust spark arresters when
they are operated in certain locations where unarrested sparks
may present a fire hazard. The muffler included with this welder
has been modified and now qualifies as a spark arrester. Spark
arresting mufflers will have a clean out service plug and will have
"USDA FS 5100-1c QUALIFIED SPARK ARRESTER" or "US FOREST
SERVICE APPROVED" stamped on the muffler shell. Any spark
arrester must be serviced and properly maintained.
CAUTION
An incorrect 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 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
TABLE A.1 COMBINED LENGTH OF ELECTRODE
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
or
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 connected 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.
