General Safety
(Continued)
welder in areas where flammable or
explosive vapors may be present.
Take precautions to ensure flying
sparks and heat do not cause flames
in hidden areas, cracks, etc.
Fire hazard! Do not
weld on containers
or pipes that contain or have contained
flammable materials or gaseous or liquid
combustibles.
Arc welding closed
cylinders or containers
such as tanks or drums
can cause explosion if
not properly vented!
Verify that any cylinder or container to
be welded has an adequate ventilation
hole, so that expanding gases can be
released.
Do not breathe fumes
produced by arc welding
operation. These fumes
are dangerous. If
welding area cannot be
adequately ventilated, be sure to use
an air-supplied respirator.
Keep head and face out of welding
fumes.
Extremely toxic fumes are created
when galvanized or cadmium plated
metals or metals which contain zinc,
mercury or beryllium are heated.
Complete the following precautions
before performing electric arc
welding operations on these metals:
a. Remove coating from base metal.
b. Make sure welding area is well
ventilated.
c. Use an air-supplied respirator.
The electromagnetic field
generated during arc
welding may interfere
with the operation of
various electrical and
electronic devices such as cardiac
pacemakers. Persons using such devices
should consult with their physician prior
to performing any electric arc welding
operations.
Route wire gun and work cables
together and secure with tape when
possible.
Never wrap arc welder cables around
the body.
Always position wire gun and work
leads on the same side of the body.
Exposure to electromagnetic fields
during welding may have other
health effects which are not known.
Always be sure
welding area is
secure and free of hazards (sparks,
flames, glowing metal or slag) prior to
leaving. Be sure equipment is turned off
and excess wire is cut off. Be sure cables
are loosely coiled and out of the way. Be
sure all metal and slag has cooled.
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 and arcs.
Install and secure cylinders in an
upright position by chaining them
to stationary support or equipment
cylinder rack to prevent falling or
tipping.
Keep cylinders away from any
welding or other electrical circuits.
Never allow a welding electrode to
touch any cylinder.
Use only correct shielding gas
cylinders, regulators, hoses and
fittings designed for the specific
application; maintain all parts
properly.
Turn face away from valve outlet
when opening cylinder valve.
Keep protective cap in place over
valve except when cylinder is in use
or connected for use.
Read and follow
instructions on
compressed gas
cylinders, associated
equipment, and CGA

Standards.

flammable gasses such as carbon
dioxide, argon, helium or mixtures of
one or more of these gasses are
suitable for MIG welding.
