Thats
why
when
Niels Miller first started
building
arc
welders
in
1929,
he made
sure
his
products
offered
long-lasting
value
and
superior quality.
Like
you,
his
customers
couldnt
afford
anything
less.
Miller
products
had
to
be
more
than the best
they
could
be.
They
had
to
be the best
you
could
buy.
Today,
the

Hot
metal
and
sparks
blow
out
from
the
cutting
arc.
The
flying
sparks
and hot
metal,
hot
workpiece,
and
hot
equipment
can cause
fires
and bums.
Check
and
be
sure
the
area
is
safe
before
doing
any
cutting.

Protect
yourself
and
others
from
flying
sparks
and hot metal.

Do
not
cut
where
flying
sparks
can
strike
flammable
material.

Remove
all
flammables
within 35
ft
(10.7
m)
of the
cutting
arc.
If
this
is
not
possible,
tightly
cover
them
with
approved
covers.

Be
alert
that
sparks
and
hot materials
from
cutting
can
easily
go
through
small cracks and
openings
to
adjacent
areas.

Watch
br

and
keep
a
fire
extinguisher
nearby.

Be
aware
that
cutting
on
a
ceiling,
floor,
bulkhead,
or
partition
can
cause
fire
on
the hidden
side.

Do
not
cut
on
closed
containers such
as
tanks
or
drums.

Connect
work cable
to
the work
as
close
to
the
cutting
area
as
practical
to
prevent
cutting
current
from
traveling long, possibly
unknown
paths
and
causing
electric shock
and
fire hazards.

Never
cut
containers with
potentially
flammable
materials inside

they
must
be
emptied
and
properly
cleaned

ELECTRIC SHOCK
can~
kill
~ki~,
I
Touching
live
electrical
parts
can
cause
fatal
I
shocks
or
severe
burns. The
torch and
work circuit
are
electrically
live whenever the
output
is
on.
The

input
power
circuit
and machine
internal circuits
are
also
live

Plasma
arc
cutting
requires
higher
voltages
than
welding
to start
and
maintain the
arc
(200
to
400 volts dc
are
common),
but also
uses
torches
designed
with
safety
interlock
systems
which
turn
off the
machine when
the
shield

is
loosened

adds
that
lighter
filter shades
may
be used when
the

As this
is
normally
the

fled
by
OSHA
(see

Standards).

Use
approved
ear
plugs
or
ear


Warn
others
nearby
about
noise
hazard.
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

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

