BATTERY ACID can burn eyes and skin.

Wear gloves and eye protection and be careful when working near battery.

Follow instructions printed on battery.

IMPORTANT: To prevent ELECTRICAL DAMAGE WHEN:

a)Installing new batteries.

b)Using a booster.

Use correct polarity — Negative Ground.

To prevent BATTERY BUCKLING, tighten nuts on bat- teries only until snug. DO NOT OVERTIGHTEN.

WARNING

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.

Work Cables.

Spark Arrester and Muffler may be hot!

Allow engine to cool before servicing

spark arrester!

Do not operate engine while servicing spark arrester!

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 loca- tions where unarrested sparks may present a fire haz- ard. The muffler included with this welder has been modified and now qualifies as a spark arrester. Mufflers on machines manufactured before this change do not qualify as spark arresters and when required by local regulations, a suitable spark arrestor must be installed. Spark arresting mufflers will have a clean out service plug and will have “USDA FS 5100- 1c QUALIFIED SPARK ARRESTER” 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.

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.
