When this welder is mounted on a truck or trailer, it’s frame must be securely connected to the metal frame of the vehicle.
Where this engine driven welder is connected to premises wiring such as that in your home or shop, it’s frame must be connected to the system earth ground. See further connection instructions in the section enti- tled “Standby Power Connections”, as well as the arti- cle 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 front of the welder.
Spark Arrester
Some federal, state, or local laws may require that gasoline engines be equipped with exhaust spark arresters 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 arrester. When required by local regulations, the
Machine Grounding
Because this portable engine driven welder or genera- tor creates it’s own power, it is not necessary to con- nect it’s frame to an earth ground, unless the machine is connected to premises wiring (your home, shop, etc.).
To prevent dangerous electric shock, other equipment to which this engine driven welder supplies power must:
•be grounded to the frame of the welder using a grounded type plug, or
•be double insulated.
CAUTION
An incorrect arrester may lead to damage to the engine or adversely affect performance.
Trailers
The recommended trailer for use with this equipment for in plant and yard towing by a vehicle is Lincoln’s
