YING
SPARKS

Sparks
and
hot
metal
blow
out
from
the
cutting
arc.
Chipping

ARC
RAYS

Arc
rays
from
the
cutting
process
produce
intense

infrared)
rays
that
can
burn
eyes
and
skin.
Wear
face
protection
(helmet
or
shield)
with
correct
shade
of
filter
to
protect
your
face
and
eyes
when
cutting
or
watching.
ANSI
Z49.1
(see
Safety

suggests
a
No.
9
shade
(with
No.
8
as
minimum)
for
all
cutting
currents
less
than
300
amperes.
Z49.
1
adds
that
lighter
filter
shades
may
be
used
when
the
arc
is
hidden
by
the
workpiece.
As
this
is
normally
the
case
with
low
current
cutting,
the
shades
suggested
in
Table
1
are
provided
for
the
oper
ators
convenience.
Wearapproved
safety
glasses
with
side
shields
under
your
helmet
or

Use
protective
screens
or
barriers
to
protect
others
from
flash
and
glare;
warn
others
not
to
watch
the
arc.
Wear
protective
clothing
made
from
durable,
flame-resistant
material
(leather

Cutting
produces
fumes
and
gases.
Breathing
these
fumes
and
gases
can
be
hazardous
to
your
health.
Keep
your
head
out
of
the
fumes.
Do
not
breathe
the
fumes.
If
inside,
ventilate
the
area
and/or
use
exhaust
at
the
arc
to
remove
cuthng
fumes
and
gases.
If
ventilation
is
poor,
use
an
approved
air-supplied
respirator.
Read
the
Material
Safety
Data
Sheets
(MSDS5)
and
the
manufac
turers
instruction
for
metals
to
be
cut,
coatings,
and
cleaners.
Work
in
a
confined
space
only
if
it
is
well
ventilated,
or
while
wearing
an
air-supplied
respirator.
Fumes
from
cutting
and
oxygen
depletion
can
alter
air
quality
causing
injury
or
death.
Be
sure
the
breathing
air
is
safe.
Do
not
cut
in
locations
near
degreasing,
cleaning,
or
spraying
op
erations.
The
heat
and
rays
of
the
arc
can
react
with
vapors
to
form
highly
toxic
and
irritating
gases.
Do
not
cut
on
coated
metals,
such
as
galvanized,
lead,
or
cadmium
plated
steel,
unless
the
coating
is
removed
from
the
cutting
area,
the
area
is
well
ventilated,
and
if
necessary,
while
wearing
an
air-supplied
respirator.
The
coatings
and
any
metals
containing
these
elements
can
give
off
toxic
fumes
when
cut.
Do
not
cut
containers
with
toxic
or
reactive
materials
inside
or
containers
that
have
held
toxic
or
reactive
materials
they
must
be
emptied

PLASMA
ARC
can
cause
injury
I
~
The
heat
from
the
plasma
arc
can
cause
serious
burns.
The
force
of
the
arc
adds
greatly
to
the
burn
hazard.
The
intensely
hot
and
powerful
arc
can
quickly
cut
through
gloves
and
tissue.
Keep
away
from
the
torch
tip.
Do
not
grip
material
near
the
cutting
path.
The
pilot
arc
can
cause
burns
keep
away
from
torch
tip
when
trig
ger
is
pressed.
Wear
proper
flame-retardant
clothing
covering
all
exposed
body
areas.
Point
torch
away
from
your
body
and
toward
work
when
pressing
the
torch
trigger
pilot
arc

Turn
off

Use
only
torch(es)
specified

a
cylinder
can
explode.
Since
gas
cylin

are
normally
part
of

them
carefully.
Protect

in
an
upright

by
chaining
them
to
a

to
prevent

away
from
any
cutting
or

electrical
circuits.
Never
allow
electrical
contact
between
a
plasma
arc
torch
and
a
cylinder.
Never
cut

will
result.
Use

application;
maintain
them
and
