SAFETY PRECAUTIONS FOR GTAW TORCHES
Always
wear
dry
insulating gloves.
Insulate
yourself
from work and
ground.
Do
not
touch live electrode
or
electrical
parts.
Repair
or
replace
worn,
damaged,
or
cracked
torch
or
cable insulation.
Turn off
welding
power
source
before
changing
tungsten
electrode
or
torch
parts.
Keep
all
covers
and handle
securely
in
ARC RAYS
can
burn eyes and skin.
Wear
welding
helmet with correct shade of filter.
Wear
correct
eye and
body protection.
Cover
exposed
skin.
FUMES
AND GASES
can
be hazardous
to
your health.
Keep
your head
out
of the fumes.
Ventilate
area,
or
use
breathing
device.
Read Material
Safety
Data Sheets
(MSDSs)
and
manufacturers
instructions for material used.
WELDING
can cause
fire
or
explosion.
1.
Do not weld
near
flammable material.
2.
Do
not
weld
on
closed containers.
3.
Watch for
fire;
keep
extinguisher
nearby.
HOT SURFACES
can
burn skin.
1.
Allow torch
to cool
before
touching.
2.
Do
not touch hot metal.
3.
Protect hot metal from
contact
by
others.
NOISE
can
damage hearing;
SOME
APPLICATIONS,
SUCH AS
PULSING,
are
noisy.
1.
Check for noise
level limits
exceeding
those
specified by
OSHA.
2.
Use
approved
ear
plugs
or
ear
muffs if noise
level is
high.
3.
Warn others
nearby
about noise hazard.
EMF INFORMATION
a
WARNING
GTAW WELDING
can
be hazardous.
PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH. KEEP CHILDREN
AWAY. PACEMAKER WEARERS KEEP AWAY UNTIL
CONSULTING YOUR DOCTOR.
In
welding,
as
in
most
jobs,
exposure
to
certain hazards
occurs.
Welding
is safe when
precautions
are
taken. The
safety
information
given
below is
only
a
summary of the
more
complete safety
information found in the
welding
power
source
Owners
Manual. Read and follow all
safety precautions.
HAVE ALL
INSTALLATION, OPERATION, MAINTENANCE,
AND
QUALIFIED PEOPLE.
ELECTRIC SHOCK
can
kill.

Considerations About
Welding
And The Effects Of Low
Frequency
Electric And
Magnetic
Fields
The

from the General Conclusions Section
of the U.S.
Congress,

&

(Washington,

there is
now
a
very
large
volume of scientific
findings
based
on
experiments
at
the
cellular level and from studies with animals and
people
which
clearly
establish that low
frequency magnetic
fields
can
interact
with,
and
produce
changes
in,
biological
systems.
While most of this work is
of very
high quality,
the results
are
complex.
Current scientific
understanding
does
not
yet
allow
us
to
interpret
the
evidence
in
a
single
coherent framework.
Even
more
frustrating,
it does not
yet
allow
us
to
draw definite conclusions about
questions
of
possible
risk
or
to
offer clear science-based advice
on
strategies
to
minimize
or
avoid
potential
risks.
To reduce
magnetic
fields
in
the
workplace,
use
the
following
procedures:
1.
Keep
cables close
together by twisting
or
taping
them.
2.
Arrange
cables
to
one
side and away from the
operator.
3.
Do
not
coil
or
drape
cables around the
body.
4.
Keep welding
power
source
and cables
as
far away
as
practical.
5.
Connect work
clamp
to
workpiece
as
close
to
the weld
as
possible.
About Pacemakers:
The
above
procedures
are
among
those
also
normally
recommended for
pacemaker
wearers.
Consult your doctor for
complete
information.
