A. Burn Protection
Comply with precautions in 1-2.
The welding arc is intense and visibly
bright. Its radiation can damage eyes,
penetrate lightweight clothing, reflect
from light-colored surfaces, and burn
the skin and eyes. Skin burns resemble
acute sunburn; those from gas-shielded
arcs are more severe and painful. DON’T
GET BURNED; COMPLY WITH PRE-
CAUTIONS.
1. Protective Clothing
Wear long-sleeve clothing in addition to
gloves, hat, and shoes. As necessary,
use additional protective clothing such
as leather jacket or sleeves, ameproof
apron, and re-resistant leggings. Avoid
outer garments of untreated cotton.
Bare skin protection. Wear dark, sub-
stantial clothing. Button collar to protect
chest and neck, and button pockets to
prevent entry of sparks.
2. Eye and Head Protection
Protect eyes from exposure to arc. Eyes
may be damaged by radiant energy
when exposed to the electric arc, even
when not looking in the direction of the
arc. Never look at an electric arc without
protection.
Welding helmet or shield containing a
lter plate shade no. 12 or denser must
be used when welding. Place over face
before striking arc.
Protect lter plate with a clear cover plate.
Cracked or broken helmet or shield
should NOT be worn; radiation can be
passed through to cause burns.
Cracked, broken, or loose lter plates
must be replaced IMMEDIATELY.
Replace clear cover plate when broken,
pitted, or spattered.
Flash goggles with side shields MUST be
worn under the helmet to give some pro-
tection to the eyes should the helmet not
be lowered over the face before an arc
is struck. Looking at an arc momentarily
with unprotected eyes (particularly a high
intensity gas-shielded arc) can cause a
retinal burn that may leave a permanent
dark area in the eld of vision.
3. Protection of Nearby Personnel
Enclose the welding area. For production
welding, a separate room or enclosed
bay is best. In open areas, surround the
operation with low-reective, noncom-
bustible screens or panels. Allow for free
air circulation, particularly at oor level.
Viewing the weld. Provide face shields
for all persons who will be looking directly
at the weld.
Others working in area. See that all per-
sons are wearing ash goggles.
Before starting to weld, make sure that
screen aps or bay doors are closed.
B. Toxic Fume Prevention
Comply with precautions in 1-2B.
Generator engine exhaust must be
vented to the outside air. Carbon mon-
oxide can kill.
C. Fire and Explosion Prevention
Comply with precautions in 1-2C.
Equipment’s rated capacity. Do not over-
load arc welding equipment. It may over-
heat cables and cause a re.
Loose cable connections may overheat or
ash and cause are.
Never strike an arc on a cylinder or other
pressure vessel. It creates a brittle area
that can cause a violent rupture or lead to
such a rupture later under rough handling.
D. Compressed Gas Equipment
Comply with precautions in 1-2D.
E. Shock Prevention
Exposed electrically hot conductors or
other bare metal in the welding circuit, or in
ungrounded, electrically - HOT equipment
can fatally shock a person whose body
becomes a conductor. DO NOT STAND, SIT,
LIE, LEAN ON, OR TOUCH a wet surface
when welding without suitable protection.
To protect against shock:
Keep body and clothing dry. Never work
in damp area without adequate insulation
against electrical shock. Stay on a dry
duckboard, or rubber mat when dampness
or sweat cannot be avoided. Sweat, sea
water, or moisture between body and an
electrically HOT part - or grounded metal
- reduces the body surface electrical resis-
tance, enabling dangerous and possibly
lethal currents to ow through the body.
1. Grounding the Equipment
When installing, connect the frames of
each unit such as welding power source,
control, work table, and water circulator to
the building ground. Conductors must be
adequate to carry ground currents safely.
Equipment made electrically HOT by stray
currents may shock, possibly fatally. Do
NOT GROUND to electrical conduit, or to a
pipe carrying ANY gas or a ammable liquid
such as oil or fuel.
Three-phase connection. Check phase
requirement of equipment before install-
ing. If only three-phase power is available,
connect single-phase equipment to only two
wires of the three-phase line. Do NOT con-
nect the equipment ground lead to the third
(live) wire, or the equipment will become
electrically HOT - a dangerous condition
that can shock, possibly fatally.
Before welding, check ground for continuity.
Be sure conductors are touching bare metal
of equipment frames at connections.
If a line cord with a ground lead is provided
with the equipment for connection to a
switch box, connect the ground lead to
the grounded switch box. If a three-prong
plug is added for connection to a grounded
mating receptacle, the ground lead must be
connected to the ground prong only. If the
line cord comes with a three-prong plug,
connect to a grounded mating receptacle.
Never remove the ground prong from a plug,
or use a plug with a broken ground prong.
2. Connectors
Fully insulated lock-type connectors should
be used to join welding cable lengths.
3. Cables
Frequently inspect cables for wear,
cracks, and damage. IMMEDIATELY
REPLACE those with excessively worn
or damaged insulation to avoid possibly
lethal shock from bared cable. Cables
with damaged areas may be taped to give
resistance equivalent to original cable.
Keep cable dry, free of oil and grease,
and protected from hot metal and sparks.
4. Terminals and Other Exposed Parts
Terminals and other exposed parts of
electrical units should have insulating
covers secured before operation.
5. Electrode Wire
Electrode wire becomes electrically HOT
when the power switch of gas metal-arc
welding equipment is ON and welding
gun trigger is pressed. Keep hands and
body clear of wire and other HOT parts.
6. Safety Devices
Safety devices such as interlocks and
circuit breakers should not be discon-
nected or shunted out.
Before installation, inspection, or service
of equipment, shut OFF all power, and
remove line fuses (or lock or red-tag
switches) to prevent accidental turning
ON of power. Disconnect all cables from
welding power source, and pull all 115
volts line-cord plugs.
Do not open power circuit or change
polarity while welding. If, in an emer-
gency, it must be disconnected, guard
against shock burns or ash from switch
arcing.
Leaving equipment unattended. Always
shut OFF, and disconnect all power to
equipment.
Power disconnect switch must be avail-
able near the welding power source.
