as
in
most
jobs,
exposure
to
certain hazards
occurs.
Welding
is safe
when
precautions
are
taken. The
safety
information
given

of
the
more
complete

ELECTRIC SHOCK
can
kill.
Touching
live electrical
parts
can
cause
fatal
shocks
or severe
burns. The
electrode and work circuit
is
electrically
live whenever
the
output
is
on.
The
input
power
circuit and machine internal
circuits
are
also
live when
power
is
on.
In

or
automatic
wire
welding,
the
wire,
wire
reel,
drive roll
housing,
and all metal
parts
touching
the
welding
wire
are
electrically
live.
Incorrectly
installed
or
improperly
grounded
equipment
is
a
hazard.
1.
Do
not
touch live electrical
parts.
2.
Wear

Special
instructions for

oper
ation

not
related
to
safety.

FUMES
AND
GASES
can
be
hazardous
to
your
health.
Welding
produces
fumes and
gases.
Breathing
these
fumes and
gases
can
be hazardous
to
your
health.
Keep
your
head
out
of the
fumes.
Do
not
breath the
fumes.
If
inside,
ventilate the
area
and/or
use
exhaust
at
the
arc
to
remove
welding
fumes
and
gases.
3.
If ventilation is
poor,
use an
approved
air-supplied
respirator.
4.
Read the Material
Safety
Data
Sheets
(MSDSs)
and the
manufacturers instruction
for
metals, consumables,
coatings,
and cleaners.
5.
Work
in
a
confined
space
only
if
it is
well
ventilated,
or
while
wearing
an
air-supplied respirator.
Shielding
gases
used
for
welding
can
displace
air
causing injury
or
death. Be
sure
the
breathing
air is
safe.
6.
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.
7.
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.
Chipping
and
grinding
cause
flying
metal. As welds
cool,
they
can
throw off
slag.
