you
dont
have
time
to
do
it
any
other
way.
Thats
why
when
Neils
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
Safety
precautions.
They
will
help
you
protect
yourself
against
potential
hazards
on
the
worksite.
Weve
made
installation
and
operation
quick
and
easy.
With
Miller
you
can
count
on
years
of
reliable
service
with
proper
maintenance.

some
reason
the
unit
needs
repair,
theres
a
Troubleshooting
section
that
will
help
you
figure
out
what
the
problem
is.
The
parts
list
will
then
help
you
to
decide
which
exact
part
you
may
need
to
fix
the
problem.

(MOW)
system
drives
six
modules
from
a
single
main
transformer
and
single
3-phase
input.
Each
welding
module
features
built-in
remote
control,
a
wide
range
of
amperage
settings,
excellent
Stick
welding
characteristics,
as
well
as
true
multipro
cess
capabilities.
Modules
can
be
paralleled
for
extra
welding
power.
The
Mark
VI
operates
24
hours
a
day
with
exceptional
durability
and

circuit
is
electrically
live
whenever
the
output
is
on.
The
input

wire
welding,
the
wire,
wire
reel,
drive
roll
housing,
and
all
metal
parts
touching
the
welding
wire
are
electrically
live.
Incorrectly
installed

there
is
now
a
very
large
volume
of
scientific
findings
based
on
experiments
at
the
cellular
level

from
studies
with
animals
and
people
which
clearly
establish
that
low

While

Duty
Cycle
and
Overheating
~I~fl
~JJ~J
2000
Duty
Cycle
is
percentage
of
10
minutes
that
unit
can
weld
at
rated
load without
overheating.
If
unit
overheats,
thermostat(s)
opens,
output
stops,
and
cooling
fan
runs.
Wait
fifteen
minutes
for
unit
to
cool.
Reduce
amperage
or
voltage,
or
duty
cycle
before
welding.
A
Exceeding
duty
cycle
can
damage
unit
and
void
warranty.
The
main
transformer
of
the
poly
weld
system
has
dual
duty
cycle
ratings,
each
for
a
specific
amper
age
output
range.
If
the
unit
is
oper
ated
in
the
750
ampere
range,
the
unit
is
rated
at
100%
duty
cycle.
This
means
the
polyweld
system
can
be
operated
at
750
amperes
continuously.
When
the
unit
is
op
erated
in
the
1500
ampere
range,
it
is
rated
at
25%
duty
cycle.
The
sum
of
the
outputs
of
each
module
should
not
exceed
the
rated
duty
cycle
of
the
main
trans
former.
For
example,
the
polyweld
system
can
be
safely
operated
at
a
load
of
1000
amperes
at
80
per
cent
duty
cycle.
This
value
could
be
obtained
by
operating
four
mod
ules
at
a
load
of
250
amperes
at
80
percent
duty
cycle,
or
by
operating
six
