WARNING: These Safety Precautions are for

your protection. They summarize precaution-

ary information from the references listed in

Additional Safety Information section. Before

performing 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 pro-

cesses are noisy and require ear pro-

tection. The arc, like the sun, emits ul-

traviolet (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 weld-

ing 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.

Bystanders 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 ex-

plosions. Therefore:

1. Remove all combustible materials 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 pro-

duce 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 neces-

sary.

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

"Fire Prevention in Use of Cutting and Welding Pro-

cesses", available from the National Fire Protection Asso-

ciation, 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 move-

ment 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 mis-

take the work lead for a ground cable.

ELECTRIC AND MAGNETIC FIELDS — May

be dangerous. Electric current flowing

through any conductor causes local-

ized Electric and Magnetic Fields (EMF).

Welding and cutting current creates EMF

around welding cables and welding ma-

chines. Therefore:

1. Welders having pacemakers should consult their physi-

cian before welding. EMF may interfere with some pace-

makers.

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.

SECTION 1 SAFETY PRECAUTIONS

6

FUMES AND GASES -- Fumes and

gases, can cause discomfort or harm,

particularly in confined spaces. Do

not breathe fumes and gases. Shield-

ing gases can cause asphyxiation.

Therefore:

1. Always provide adequate ventilation in the work area by

natural or mechanical means. Do not weld, cut, or gouge

on materials such as galvanized steel, stainless steel,

copper, zinc, lead, beryllium, or cadmium unless posi-

tive mechanical ventilation is provided. Do not breathe

fumes from these materials.

2. Do not operate near degreasing and spraying opera-

tions. The heat or arc rays can react with chlorinated

hydrocarbon vapors to form phosgene, a highly toxic

gas, and other irritant gases.

3. If you develop momentary eye, nose, or throat irritation

while operating, this is an indication that ventilation is not

adequate. Stop work and take necessary steps to im-

prove ventilation in the work area. Do not continue to

operate if physical discomfort persists.

4. Refer to ANSI/ASC Standard Z49.1 (see listing below)

for specific ventilation recommendations.

5. WARNING: This product, when used for welding or

cutting, produces fumes or gases which

contain chemicals known to the State of

California to cause birth defects and, in

some cases, cancer. (California Health &

Safety Code

§25249.5 et seq.)

CYLINDER HANDLING -- Cylinders, if mis-

handled, can rupture and violently re-

lease gas. Sudden rupture of cylinder,

valve, or relief device can injure or kill.

Therefore:

1. Use the proper gas for the process and use the proper

pressure reducing regulator designed to operate from

the compressed gas cylinder. Do not use adaptors.

Maintain hoses and fittings in good condition. Follow

manufacturer's operating instructions for mounting regu-

lator to a compressed gas cylinder.

2. Always secure cylinders in an upright position by chain

or strap to suitable hand trucks, undercarriages, benches,

walls, post, or racks. Never secure cylinders to work

tables or fixtures where they may become part of an

electrical circuit.

3. When not in use, keep cylinder valves closed. Have

valve protection cap in place if regulator is not con-

nected. Secure and move cylinders by using suitable

hand trucks. Avoid rough handling of cylinders.

4. Locate cylinders away from heat, sparks, and flames.

Never strike an arc on a cylinder.

5. For additional information, refer to CGA Standard P-1,

"Precautions for Safe Handling of Compressed Gases in

Cylinders", which is available from Compressed Gas

Association, 1235 Jefferson Davis Highway, Arlington,

VA 22202.

EQUIPMENT MAINTENANCE -- Faulty or im-

properly maintained equipment can cause

injury or death. Therefore:

1. Always have qualified personnel perform the installa-

tion, troubleshooting, and maintenance work. Do not

perform any electrical work unless you are qualified to

perform such work.

2. Before performing any maintenance work inside a power

source, disconnect the power source from the incoming

electrical power.

3. Maintain cables, grounding wire, connections, power

cord, and power supply in safe working order. Do not

operate any equipment in faulty condition.

4. Do not abuse any equipment or accessories. Keep

equipment away from heat sources such as furnaces,

wet conditions such as water puddles, oil or grease,

corrosive atmospheres and inclement weather.

5. Keep all safety devices and cabinet covers in position

and in good repair.

6. Use equipment only for its intended purpose. Do not

modify it in any manner.
