From
Miller
to
You
Thank
you
and
congratulations
on
choosing
Miller.
Now
you
can
get
the
job
done
and
get
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

hazardous
=~u~
Keep

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
(MSDS5)
and
the
manufacturers
instructions
for
metals,
consumables,
coatings,
cleaners,
and
degreasers.
Work
in
a
confined
space
only
if
it
is
well
ventilated,
or
while
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
degreasing,
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.
Welding
produces
fumes
and
gases.
Breathing
these
fumes
and
gases
can
be
hazardous
to
your
health.

objects
can
cause

explosion,
overheating,
or
fire.
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
35ft
(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

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.l
(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

hazards.
Do
not
use

Shielding
gas
cylinders
contain

a
cylinder
can
explode.
Since
gas
cylinders
are

to
treat
them
carefully.
Protect
compressed

cylinders
from
excessive

Install
cylinders
in
an
upright

by
securing
to
a
