SAFETY DEPENDS ON YOU

Lincoln arc welding and cutting equipment is designed and built

with safety in mind. However, your overall safety can be increased

by proper installation ... and thoughtful operation on your part.

DO NOT INSTALL, OPERATE OR REPAIR THIS EQUIPMENT

WITHOUT READING THIS MANUAL AND THE SAFETY

PRECAUTIONS CONTAINED THROUGHOUT. And, most importantly,

think before you act and be careful.

This statement appears where the information must be followed

exactly to avoid serious personal injury or loss of life.

This statement appears where the information must be followed

to avoid minor personal injury or damage to this equipment.

KEEP YOUR HEAD OUT OF THE FUMES.

DON’T get too close to the arc.

Use corrective lenses if necessary

to stay a reasonable distance

away from the arc.

READ and obey the Safety Data

Sheet (SDS) and the warning label

that appears on all containers of

welding materials.

USE ENOUGH VENTILATION or

exhaust at the arc, or both, to

keep the fumes and gases from

your breathing zone and the general area.

IN A LARGE ROOM OR OUTDOORS, natural ventilation may be

adequate if you keep your head out of the fumes (See below).

USE NATURAL DRAFTS or fans to keep the fumes away

from your face.

If you develop unusual symptoms, see your supervisor.

Perhaps the welding atmosphere and ventilation system

should be checked.

WEAR CORRECT EYE, EAR &

BODY PROTECTION

PROTECT your eyes and face with welding helmet

(See ANSI Z49.1).

PROTECT your body from welding spatter and arc

leggings, and high boots.

PROTECT

with protective screens or barriers.

IN SOME AREAS, protection from noise may be appropriate.

BE SURE protective equipment is in good condition.

Also, wear safety glasses in work area

AT ALL TIMES.

SPECIAL SITUATIONS

DO NOT WELD OR CUT containers or materials which previously

had been in contact with hazardous substances unless they are

properly cleaned. This is extremely dangerous.

DO NOT WELD OR CUT painted or plated parts unless special

precautions with ventilation have been taken. They can release

highly toxic fumes or gases.

Additional precautionary measures

PROTECT compressed gas cylinders from excessive heat,

mechanical shocks, and arcs; fasten cylinders so they cannot fall.

BE SURE cylinders are never grounded or part of an

electrical circuit.

sible to the area being welded.

2.d.5. Do not work next to welding power source.

SAFETY

Safety 02 of 04 - 5/16/2018

ELECTRIC SHOCK

CAN KILL.

3.a. The electrode and work (or ground) circuits are

electrically “hot” when the welder is on. Do

not touch these “hot” parts with your bare skin or wet clothing.

Wear dry, hole-free gloves to insulate hands.

3.b. Insulate yourself from work and ground using dry insulation.

Make certain the insulation is large enough to cover your full area

of physical contact with work and ground.

In addition to the normal safety precautions, if

welding must be performed under electrically

hazardous conditions (in damp locations or while

wearing wet clothing; on metal structures such as

positions such as sitting, kneeling or lying, if there

is a high risk of unavoidable or accidental contact

with the workpiece or ground) use the following

equipment:

• Semiautomatic DC Constant Voltage (Wire) Welder.

• DC Manual (Stick) Welder.

• AC Welder with Reduced Voltage Control.

3.c. In semiautomatic or automatic wire welding, the electrode,

electrode reel, welding head, nozzle or semiautomatic welding

gun are also electrically “hot”.

3.d. Always be sure the work cable makes a good electrical

connection with the metal being welded. The connection should

be as close as possible to the area being welded.

3.e. Ground the work or metal to be welded to a good electrical (earth)

ground.

3.f. Maintain the electrode holder, work clamp, welding cable and

welding machine in good, safe operating condition. Replace

damaged insulation.

3.g. Never dip the electrode in water for cooling.

3.h. Never simultaneously touch electrically “hot” parts of electrode

holders connected to two welders because voltage

between the

two can be the total of the open circuit voltage of both

welders.

themselves to the arc rays or to hot spatter or metal.

FUMES AND GASES

CAN BE DANGEROUS.

5.a. Welding may produce fumes and gases

hazardous to health. Avoid breathing these

fumes and gases. When welding, keep your head out of the fume.

Use enough ventilation and/or exhaust at the arc to keep fumes

and gases away from the breathing zone. When welding

hardfacing (see instructions on container or SDS)

or on lead or cadmium plated steel and other

metals or coatings which produce highly toxic

fumes, keep exposure as low as possible and

within applicable OSHA PEL and ACGIH TLV limits

using local exhaust or mechanical ventilation

unless exposure assessments indicate otherwise.

outdoors, a respirator may also be required.

Additional precautions are also required when

welding

on galvanized steel.

5. b. The operation of welding fume control equipment is affected by

various factors including proper use and positioning of the

welding procedure and application involved. Worker exposure

level should be checked upon installation and periodically

thereafter to be certain it is within applicable OSHA PEL and

ACGIH TLV limits.

5.c. Do not weld in locations near chlorinated hydrocarbon vapors

coming from degreasing, cleaning or spraying operations. The

heat and rays of the arc can react with solvent vapors to form

phosgene, a highly toxic gas, and other irritating products.

5.d. Shielding gases used for arc welding can displace air and

cause

injury or death. Always use enough ventilation, especially in

5.e. Read and understand the manufacturer’s instructions for this

equipment and the consumables to be used, including the

Safety Data Sheet (SDS) and follow your employer’s safety

practices. SDS forms are available from your welding

distributor or from the manufacturer.

FIRE OR EXPLOSION.

6.a.

this is not possible, cover them to prevent the welding sparks

materials from welding can easily go through small cracks and

openings to adjacent areas. Avoid welding near hydraulic lines.

6.b. Where compressed gases are to be used at the job site, special

precautions should be used to prevent hazardous situations.

Refer to “Safety in Welding and Cutting” (ANSI Standard Z49.1)

and the operating information for the equipment being used.

6.c. When not welding, make certain no part of the electrode circuit is

touching the work or ground. Accidental contact can cause

6.d. Do not heat, cut or weld tanks, drums or containers until the

proper steps have been taken to insure that such procedures

They can cause an explosion even though they have been

“cleaned”. For information, purchase “Recommended Safe

Practices for the Preparation for Welding and Cutting of

Containers and Piping That Have Held Hazardous Substances”,

AWS F4.1 from the American Welding Society

(see address above).

6.e. Vent hollow castings or containers before heating, cutting or

welding. They may explode.

6.f. Sparks and spatter are thrown from the welding arc. Wear oil free

trousers, high shoes and a cap over your hair. Wear ear plugs

safety glasses with side shields when in a welding area.

6.g. Connect the work cable to the work as close to the welding area

as practical. Work cables connected to the building framework or

other locations away from the welding area increase the

possibility of the welding current passing through lifting chains,

hazards or overheat lifting chains or cables until they fail.

6.h. Also see item 1.c.

6.I. Read and follow NFPA 51B “Standard for Fire Prevention During

Welding, Cutting and Other Hot Work”, available from NFPA, 1
