and
regularly
there
after.

ARC
WELDING
Comply
with
precautions
in
1-1,
1-2,
and
this
section.
Arc
Welding,
properly
done,
is
a
safe
process,
but
a
careless
opera
tor
invites
trouble.
The
equipment
carries
high
currents
at
significant
voltages.
The
arc
is
very
bright
and
hot.
Sparks
fly,
fumes
rise,
ultraviolet
and
infrared
energy
radiates,
weld
ments
are
hot,
and
compressed
gases
may
be
used.
The
wise
operator
avoids
unnecessary
risks
and
protects
himself
and
others
from
accidents.
Precautions
are
described
here
and
in
standards
referenced
in
index.
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.
DONT
GET
BURNED;
COMPLY
WITH
PRECAUTIONS.
1.
Protective
Clothing
Wear
long-sleeve
clothing
(particularly
for
gas-shielded
arc)
in
addition
to
gloves,
hat,
and
shoes
(1-2A).
As
necessary,
use
additional
protective
clothing
such
as
leather
jacket
or
sleeves,
flame-proof
apron,
and
fire-resistant
leggings.
Avoid
outergarments
of
untreated
cotton.
Bare
skin
protection.
Wear
dark,
substantial
clothing.
Button
collar
to
protect
chest
and
neck
and
button
pockets
to
pre
vent
entry
of
sparks.
2.
Eye
and
Head
Protection
Protect
eyes
from
exposure
to
arc.
NEVER
look
at
an
elec
tric
arc
without
protection.
Welding
helmet
or
shield
containing
a
filter
plate
shade
no.
12
or
denser
must
be
used
when
welding.
Place
over
face
before
striking
arc.
Protect
filter
plate
with
a
clear
cover
plate.
Cracked
or
broken
helmet
or
shield
should
NOT
be
worn;
radiation
can
pass
through
to
cause
burns.
Cracked,
broken,
or
loose
filter
plates
must
be
replaced
IM
MEDIATELY.
Replace
clear
cover
plate
when
broken,
pitted,
or
spattered.
Flash
goggles
with
side
shields
MUST
be
worn
under
the
helmet
to
give
some
protection
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
field
of
vision.
3.
Protection
of
Nearby
Personnel
Enclosed
welding
area.
For
production
welding,
a
separate
room
or
enclosed
bay
is
best.
In
open
areas,
surround
the
operation
with
low-reflective,
non.cornbustible
screens
or
panels.
Allow
for
free
air
circulation,
particularly
as
floor
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
persons
are
wearing
flash
goggles.
Before
starting
to
weld;
make
sure
that
screen
flaps
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
monoxide
can
kill.
C.
Fire
and
Explosion
Prevention
Comply
with
precautions
in
1-2C.
Equipments
rated
capacity.
Do
not
overload
arc
welding
equipment.
It
may
overheat
cables
and
cause
a
fire.
Loose
cable
connections
may
overheat
or
flash
and
cause
a
fire.
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
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
sur
face
when
welding,
without
suitable
protection.
To
protect
against
shock:
Keep
body
and
clothing
dry.
Never
work
in
damp
area
with
out
adequate
insulation
against
electrical
shock.
Stay
on
a
dry
duckboard,
or
rubber
mat
when
dampness
or
sweat
can
not
be
avoided.
Sweat,
sea
water,
or
moisture
between
body
and
an
electrically
HOT
part
-
or
grounded
metal
-
reduces
the
body
surface
electrical
resistance,
enabling
dangerous
and
possibly
lethal
currents
to
flow
through
the
body.
1.
Grounding
the
Equipment
When
installing,
connect
the
frames
of
each
unit
such
as
welding
power
source,
control,
i&ork
table,
and
water
circula
tor
to
the
building
ground.
Conductors
must
be
adequate
to
carry
ground
currents
safely.
Equipment
made
electrically
HOT
by
stray
current
may
shock,
possibly
fatally.
Do
NOT
GROUND
so
electrical
conduit,
or
to
a
pipe
carrying
ANY
gas
or
a
flammable
liquid
such
as
oil
or
fuel.
Three-phase
connection.
Check
phase
requirement
of
equip
ment
before
installing.
If
only
3-phase
power
is
available,
connect
single-phase
equipment
to
only
two
wires
of
the
3-phase
line.
Do
NOT
connect
the
equipment

lead
to
the

cally
HOT
-
a
dangerous
condition
that
can
shock,
possibly
fatally.
Before
welding,
check
ground
for
continuity.
Be
sure
conduc
tors
are
touching
bare
metal
of
equipment
frames
at
connec
tions.
If
a
line
cord
with
a
ground
lead
is
provided
with
the
equip
ment
for
connection
to
a
switchbox,
connect
the
ground
lead
to
the
grounded
switchbox.
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
off
ground
prong.
