INSTALLATION |
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 does not qualify as a spark arrestor. When required by local regulations, a suitable spark arrestor, must be installed and properlyCAUTIONmaintained.
An incorrect arrestor 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 output studs. The welding process dic- tates the polarity of the electrode cable. These con- nections 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.

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 grounding 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 further connection instructions in the sec- tion 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 frame- work of a building which has been effectively ground- ed. The National Electric Code lists a number of alter- nate means of grounding electrical equipment. A machine grounding stud marked with the symbol is provided on the front of the welder.
