CYLINDERS
can
explode
if
damaged.
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.
4.
Never
drape
a
welding
torch
over
a
gas
cylinder.
5.
Never allow
a
welding
electrode
to
touch any
cylinder.
6.
Never weld
on a
pressurized cylinder
explosion
will result.
7.
Use
only
correct
shielding
gas
cylinders, regulators,
hoses,
and
fittings designed
for the
specific application;
maintain them and
associated
parts
in
good
condition.
8.
Turn face away from valve outlet when
opening cylinder
valve.
9.
Keep protective
cap in
place
over
valve
except
when
cylinder
is
in
use
or
connected for
use.
10. Read and follow instructions
on
compressed
gas
cylinders,
associated
equipment,
and CGA
publication
P-i listed in
Safety
Standards.
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
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,
or
fire. Check and be
sure
the
area
is safe before
doing
any
welding.
1.
Protect
yourself
and others from
flying sparks
and hot metal.
2.
Do
not
weld where
flying sparks
can
strike flammable material.
3.
Remove all flammables within 35 ft
(10.7 m)
of the
welding
arc.
If
this is
not
possible, tightly
cover
them with
approved
covers.
4.
Be alert that
welding sparks
and hot materials from
welding
can
easily
go
through
small cracks and
openings
to
adjacent
areas.
5.
Watch for
fire,
and
keep
a
fire
extinguisher nearby.
6.
Be
aware
that
welding
on a
ceiling,
floor, bulkhead,
or
partition
can cause
fire
on
the hidden side.
7.
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).
8.
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.
9.
Do not
use
welder to thaw frozen
pipes.
10. Remove stick electrode from holder
or
cut
off
welding
wire
at
contact
tip
when
not
in
use.
11.
Wear oil-free
protective garments
such
as
leather
gIove~, heavy
shirt,
cuffless
trousers,
high
shoes,
and
a
cap.
12. Remove any
combustibles,
such
as a
butane
lighter
or
matches,
from your person before
doing
any
welding.

Additional
Installation, Operation,
And Maintenance Hazards
FIRE OR EXPLOSION
can
result from
placing
unit
on,
over,
or
near
combustible surfaces.
1.
Do
not
locate unit
on, over,
or near
combustible
surfaces.
2.
Do not install unit
near
flammables.
FALLING
EQUIPMENT
can
cause
serious
personal injury
and
equipment
damage.
1.
Use
lifting
eye
to
lift unit
only,
NOT
running
gear,
gas
cylinders,
or
any other accessories.
Use
equipment
of
adequate capacity
to lift
unit.
If
using
lift forks
to
move
unit,
be
sure
forks
are
long enough
to
extend
beyond opposite
side of
unit.
HOT PARTS
can cause severe
burns.
1.
Do
not
touch hot
parts
bare handed.
2.
Allow
cooling period
before
working
on
gun
or
torch.
MOVING PARTS
can cause
injury.
1.
Keep
away from
moving
parts
such
as
fans.
2.
Keep
all
doors,
panels,
covers,
and
guards
closed
and
securely
in
place.
FIELDS
FROM
HIGH

RADIATION
can
interfere with radio
navigation, safety
services,
computers,
and
communications
equipment.
1.
Have
only
qualified
persons
