Safety - Introduction
ESAB welding equipment is designed to operate both safely and eectively. Sensible attention to operating
procedures, precautions, and safe practices is required to achieve a full measure of usefulness. Whether an
individual is involved with operation, servicing, or as an observer, compliance with established precautions
is mandatory. Failure to observe precautions could result in equipment damage, serious injury, or death.
The following precautions are guidelines when working with cutting machines and associated equipment.
More explicit precautions are found within the instruction literature. For specic safety and industry-related
information, obtain and read publications listed in Recommended References.

WARNING:TheseSafetyPrecautionsare
for your protection. They summarize
precautionary information from the
references listed in Additional Safety
Informationsection.Beforeperforming
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.Thearc,likethesun,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 equipment
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 tted with the correct lter 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 ameproof gauntlet type gloves, heavy long-
sleeve shirt, cuess 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 ameproof apron may also be desirable as protec-
tion against radiated heat and sparks.
4. Hot sparks or metal can lodge in rolled up sleeves,
trouser cus, or pockets. Sleeves and collars should
bekeptbuttoned,andopenpocketseliminatedfrom
the front of clothing.
5. Protect otherpersonnelfromarcraysandhotsparks
with a suitable non-ammable partition or curtains.
6. Use goggles over safety glasses when chipping slag
or grinding. Chipped slag may be hot and can y far.
Bystanders should also wear goggles over safety
glasses.
FIRES AND EXPLOSIONS -- Heat from
ames and arcs can start res. Hot
slag or sparks can also cause res and
explosions. Therefore:
1. Remove allcombustiblematerials wellawayfromthe
work area or cover the materials with a protective
non-ammable 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 oors or wall openings and cause a hid-
den smoldering re or res on the oor 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
workpiecehasbeencompletelycleanedsothatthere
are no substances on the work piece which might
produce ammable or toxic vapors. Do not do hot
work on closed containers. They may explode.
4. Havere extinguishingequipment handyforinstant
use, such as a garden hose, water pail, sand bucket,
or portable re extinguisher. Be sure you are trained
in its use.
5. Do not use equipment beyond its ratings. For ex-
ample, overloaded welding cable can overheat and
create a re hazard.
6. After completing operations, inspect the work area
to make certain there are no hot sparks or hot metal
whichcouldcausealaterre.Userewatcherswhen
necessary.
