From
Miller
to
You
.
Thank
you
and
congratulations
on
choosing
Miller.

it done
right.
We
know
you
dont have time
to
do
it
any
other
way.
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
people
that
build
and sell Miller
products
continue
the
tradition;
Theyre
just
as
committed
to
providing
equipment
and service
that
meets
the
high
standards
of
quality
and value
established
in
1929.
This Owners
Manual
is
designed
to
help
you
get
the
most out
of
your
Miller
products.
Please take time
to
read
the

FUMES
AND
GASES
can
be
hazardous.
Welding produces
fumes
and
gases.
Breathing
=9~
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
welding
fumes and
gases.

If
ventilation is
poor,
use an
approved air-supplied
respirator.

Read the Material
Safety
Data
Sheets
(MSDSs)
and
the
manufacturers
instructions
for
metals, consumables,
coatings,
cleaners,
and
degreasers.

Work in
a
confined
space
only
if it is
well
ventilated,
or
white
wearing
an
air-supplied respirator.
Always
have
a
trained
watch-
person
nearby.
Welding
fumes
and
gases
can
displace
air
and
lower
the
oxygen
level
causing injury
or
death.
Be
sure
the
breathing
air
is
safe.

Do
not
weld in
locations
near
degreasirig,
cleaning,
or
spraying
operations.
The heat and
rays
of
the
arc can
react
with
vapors
to
form
highly
toxic and
irritating
gases.

Do
not
weld
on
coated
metals,
such
as
galvanized,
lead,
or
cadmium
plated
steel,
unless
the
coating
is
removed from the
weld
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 if welded.

ARC
RAYS
can
burn
eyes
and
skin
Arc
rays
from the
welding
process
produce
intense
visible and invisible
(ultraviolet
and
infrared)
rays
that
can
burn
eyes
and skin.
Sparks fly
off from
the
weld.

Wear
a
welding
helmet fitted with
a
proper
shade of filter
to
protect
your
face
and
eyes
when
welding
or
watching
(see
ANSI
Z49.i
and Z87.i
listed in
Safety Standards).

Wear
approved
safety glasses
with side shields under
your
helmet.

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
and
wool)
and
foot
protection.
WELDING
an
cause
fire
or
explosion.
Welding
on
closed
containers,
such
as
tanks,
drums,
or
pipes,
can cause
them
to
blow
up.
Sparks
can
fly
off from
the
welding
arc.
The
flying
sparks,
hot
workpiece,
and
hot.equipment
can
cause
fires
and
burns.
Accidental
contact
of
electrode
to
metal
objects
can
cause
sparks,
explosion,
overheating,
orfire.
Check
and
be
sure
the
area
is
safe
before
doing
any
welding.

Protect
yourself
and
others
from
flying
sparks
and hot
metal.

Do
not
weld
where
flying
sparks
can
strike
flammable
material.

Remove all
flammables
within
35
ft
(10.7 m)
of
the
welding
arc.
If
this
is
not
possible,
tightly
cover
them with
approved
covers.

Be
alert
that
welding
sparks
and
hot
materials from
welding
can
easily
go
through
small cracks and
openings
to
adjacent
areas.

Watch for
fire,
and
keep
a
fire
extinguisher nearby.

Be
aware
that
welding
on a
ceiling,
floor, bulkhead,
or
partition
can
cause
fire
on
the
hidden
side.

Do
not
weld
on
closed containers
such
as
tanks, drums,
or
pipes,
unless
they
are
properly prepared
according
to
AWS
F4.i
(see
Safety
Standards).

Connect
work cable
to
the work
as
close
to
the
welding
area as
practical
to
prevent
welding
current
from
traveling long, possibly
unknown
paths
and
causing
electric shock and
fire
hazards.

Do
not
use
welder
to
thaw frozen
pipes.

Remove
stick
electrode from
holder
or
cut
off
welding
wire
at
contact
tip
when
not
in
use.

Wear oil-free
protective
garments
such
as
leather
gloves,
heavy
shirt,
cuffless
trousers,
high
shoes,
and
a
cap.

Remove
any
combustibles,
such
as
a
butane
lighter
or
matches,
from
your
person
before
doing
any
welding.
FLYING METAL
can
injure
eyes.

Welding,
chipping,
wire
brushing,
and
grinding
cause
sparks
and
flying
metal. As
welds
cool,
they
can
throw
off
slag.

Wear
approved
safety
glasses
with
side
shields
even
under
your
welding
helmet.
BUILDUP
OF
GAS
can
injure
or
kill

Shut
off
shielding
gas
supply
when
not
in
use.

Always
ventilate
confined
spaces
or use
1J
approved
air-supplied
respirator.
HOT
PARTS
can
cause severe
burns

Do
not
touch
hot
parts
bare handed.

Allow
cooling
period
before
working
on
gun
or
torch.
MAGNETIC
FIELDS
can
affect
pacemakers.

Pacemaker
wearers
keep
away.

Wearers should
consult their doctor
before
going
near
arc
welding, gouging,
or
spot
welding
operations.
NOISE
can
damage
hearing.
Noise from
some
processes
or
equipment
can
damage
hearing.

Wear
approved
ear
protection
if
noise level is
high.
Shielding
gas
cylinders
contain
gas
under
high
pressure.
If
damaged,
a
cylinder
can
explode.
Since
gas
cylinders
are
normally
part
of
the
welding
process,
be
sure
to
treat
them
carefully.

Protect
compressed
gas
cylinders
from excessive
heat,
mechanical
shocks,
slag,
open
flames,
sparks,
and
arcs.

Install
cylinders
in
an
upright
position
by securing
to
a
stationary
support
or
cylinder
rack
to
prevent
falling
or
tipping.

Keep
cylinders
away
from
any
welding
or
other electrical circuits.
Never
drape
a
welding
torch
over a
gas
cylinder.
Never allow
a
welding
electrode
to
touch
any
cylinder.
Never weld
on a
pressurized
cylinder

explosion
will
result.
Use
only
correct
shielding
gas
cylinders,
regulators,
hoses,
and
fittings
designed
for the
specific
application;
maintain them
and
associated
parts
in
good
condition.
Turn face
away
from
valve outlet
when
opening
cylinder
valve.
Keep protective
cap
in
place
over
valve
except
when
cylinder
is in
use or
connected

Information
Considerations
About
Welding
And The
Effects
Of
Low
Frequency
Electric
And
Magnetic
Fields
Welding
current,
as
it flows
through welding
cables,
will
cause
electro
magnetic
fields. There
has
been
and
still
is
some
cc~ncern
about
such
fields.
However,
after
examining
more
than
500
studies
spanning
17
years
of
research,
a
special
blue ribbon committee of the
National
Research Council
concluded that: The
body
of
evidence,
in
the
committees
judgment,
has
not
demonstrated
that
exposure
to
power-
frequency
electric and
magnetic
fields is
a
human-health hazard.
However,
studies
are
still
going
forth and evidence
continues
to
be
examined.
Until
the
final conclusions of
the research
are
reached,
you
may
wish
to
minimize
your
exposure
to
electromagnetic
fields
when
welding
or
cutting.
To
reduce
magnetic
fields
in the
workplace,
use
the
following
procedures:
1.
Keep
cables
close
together
by twisting
or
taping
them.
2.
Arrange
cables
to
one
side
and
away
from
the
operator.
3.
Do
not
coil
or
drape
cables
around
your
body.
4.
Keep
welding
power
source
and cables
as
far
away
from
opera
tor
as
practical.
5.
Connect
work
clamp
to
workpiece
as
close
to
the weld
as
possible.
About
Pacemakers:
Pacemaker

following
