WARNING:

 T

hese Safety Precautions are for

your protection. They summarize precautionary
information from the references listed in Addi-
tional Safety Information section. Before per-

forming any installation or operating procedures, be sure to
read and follow the safety precautions listed below as well as
all other manuals, material safety data sheets, labels, etc.
Failure to observe Safety Precautions can result in injury or
death.

PROTECT YOURSELF AND OTHERS

 -

-

 Some welding, cutting, and gouging

processes are noisy and require ear
protection. The arc, like the sun, emits
ultraviolet (UV) and other radiation and

can injure skin and eyes.  Hot metal can cause burns.
Training in the proper use of the processes and equip-
ment is essential to prevent accidents. Therefore:

1. Always wear safety glasses with side shields in any work

area, even if welding helmets, face shields, and goggles
are also required.

2. Use a face shield fitted with the correct filter and cover

plates to protect your eyes, face, neck, and ears from
sparks and rays of the arc when operating or observing
operations. Warn bystanders not to watch the arc and not
to expose themselves to the rays of the electric-arc or hot
metal.

3. Wear flameproof gauntlet type gloves, heavy long-sleeve

shirt, cuffless trousers, high-topped shoes, and a welding
helmet or cap for hair protection, to protect against arc rays
and hot sparks or hot metal. A flameproof apron may also
be desirable as protection against radiated heat and sparks.

4. Hot sparks or metal can lodge in rolled up sleeves, trouser

cuffs, or pockets. Sleeves and collars should be kept
buttoned, and open pockets eliminated from the front of
clothing

5. Protect other personnel from arc rays and hot sparks with

a suitable non-flammable partition or curtains.

6. Use goggles over safety glasses when chipping slag or

grinding. Chipped slag may be hot and can fly far. Bystand-
ers should also wear goggles over safety glasses.

FIRES AND EXPLOSIONS --

Heat from

flames and arcs  can start fires. Hot slag
or sparks can also cause fires and explo-
sions. Therefore:

1.

Remove all combustible materi-

als well away from the work area or cover the materials
with a protective non-flammable covering. Combustible
materials include wood, cloth, sawdust, liquid and gas
fuels, solvents, paints and coatings, paper, etc.

2. Hot sparks or hot metal can fall through cracks or crevices

in floors or wall openings and cause a hidden smoldering
fire or fires on the floor below. Make certain that such
openings are protected from hot sparks and metal.“

3. Do not weld, cut or perform other hot work until the

workpiece has been completely cleaned so that there are
no substances on the workpiece which might produce
flammable or toxic vapors. Do not do hot work on closed
containers. They may explode.

4. Have fire extinguishing equipment handy for instant use,

such as a garden hose, water pail, sand bucket, or
portable fire extinguisher. Be sure you are trained in its
use.

5. Do not use equipment beyond its ratings. For example,

overloaded welding cable can overheat and create a fire
hazard.

6. After completing operations, inspect the work area to make

certain there are no hot sparks or hot metal which could
cause a later fire. Use fire watchers when necessary.

7. For additional information, refer to NFPA Standard 51B,

"Fire Prevention in Use of Cutting and Welding Processes",
available from the National Fire Protection Association,
Batterymarch Park, Quincy, MA 02269.

ELECTRICAL SHOCK -- Contact with live electrical parts
and ground can cause severe injury or death. DO NOT use

AC welding current in damp areas, if
movement is confined, or if there is
danger of falling.

1.

Be sure the power

source frame (chassis) is connected to
the ground system of the input power.

2. Connect the workpiece to a good electrical ground.
3. Connect the work cable to the workpiece. A poor or

missing connection can expose you or others to a fatal
shock.

4. Use well-maintained equipment. Replace worn or dam-

aged cables.

5. Keep everything dry, including clothing, work area, cables,

torch/electrode holder, and power source.

6. Make sure that all parts of your body are insulated from

work and from ground.

7. Do not stand directly on metal or the earth while working in

tight quarters or a damp area; stand on dry boards or an
insulating platform and wear rubber-soled shoes.

8. Put on dry, hole-free gloves before turning on the power.
9. Turn off the power before removing your gloves.

10. Refer to ANSI/ASC Standard Z49.1 (listed on next page)

for specific grounding recommendations. Do not mistake
the work lead for a ground cable.

ELECTRIC AND MAGNETIC FIELDS — May be dangerous.
Electric current flowing through any conductor causes

localized Electric and Magnetic Fields
(EMF). Welding and cutting current
creates EMF around welding cables
and welding machines. Therefore:

1.

Welders having pacemakers

should consult  their physician before
welding. EMF may interfere with some

pacemakers.

2. Exposure to EMF may have other health effects which are

unknown.

3. Welders should use the following procedures to minimize

exposure to EMF:
A. Route the electrode and work cables together. Secure

them with tape when possible.

B. Never coil the torch or work cable around your body.
C. Do not place your body between the torch and work

cables. Route cables on the same side of your body.

D. Connect the work cable to the workpiece as close as

possible to the area being welded.

E. Keep welding power source and cables as far away from

your body as possible.
