Lincoln Electric IM694 RED-D-ARC D503K 5+3 HO - Manual (Page 11)

GASES FROM BATTERY can explode.
● Keep sparks, flame and cigarettes
away from battery.
To prevent EXPLOSION when:
● INSTALLING A NEW BATTERY — disconnect
negative cable from old battery first and con-
nect to new battery last.
● CONNECTING A BATTERY CHARGER —
remove battery from welder by disconnecting
negative cable first, then positive cable and
battery clamp. When reinstalling, connect
negative cable last. Keep well ventilated.
● USING A BOOSTER — connect positive lead to
battery first then connect negative lead to neg-
ative battery lead at the lower control panel
support.
BATTERY ACID can burn eyes and skin.
● Wear gloves and eye protection
and be careful when working near
battery.
● Follow instructions printed on bat-
tery.
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
batteries only until snug. DO NOT OVERTIGHTEN.
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 standard muffler included with this welder
does not qualify as a spark arrester. When required by
local regulations, a suitable spark arrester must be
installed and properly maintained.
An incorrect arrester may lead to damage to the
engine or adversely affect performance. Contact
the engine manufacturer for specific recommen-
dations.

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 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 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 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 welding generator frame foot.
