ARC
RAYS
can
burn
eyes
and

Arc
rays
from
the
welding
process
produce
intense
visible
and
invisible
(ultraviolet
and
infrared)
rays
that
can
bum
eyes
and
skin.
Sparks
fly
oft
from
the
weld.
Weara

protect
your
face
and
eyes
when
welding
or
watching
(see

listed
in
Safety
Standards).
Wear
approved

Wear
protective
clothing
made
from
durable,
flame-resistant
matenal
(leather
and
wool)
and
foot
protection.
WELDING
can
cause
fire
or
explosion.
Welding
on
closed
containers,
such
as
tanks,
drums,
or
pipes,
can
cause
them
to
blow
up.
Sparks
can
fly
oft
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
F4.1
(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

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
oft
slag.
Wear
approved
safety
glasses
with
side
shields
even
under
your
welding
helmet.

The
user
is
responsible
for
having
a

promptly
correct

resulting
from

If
notified
by

Be
sure
all

must
take
extra
measures
such
as
moving

at

Amperes
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
modules
at
a
load
of
167

at
