SAFETY
PRECAUTIONS
ALWAYS
EMPLOY
PRECAUTIONARY
MEASURES
DURING ARC WELDING
OPERATIONS
TO EN-
SURE
MAXIMUM
PERSONAL
SAFETY
AND THE
SAFETY
OF
NEARBY
PERSONNEL.
Operate And
Maintain
The Machine And Its
Equipment Properly.
Do not overload the cables. Do not use worn or
poorly connected cables. Do not allow the
welding cables to contact hot metal, water, oil or
grease. Prevent cables from becoming a stumbl-
ing hazard by keeping them in order and out of the
way.
Use electrode holders that are completely in-
sulated.
Do not use holders with defective jaws.
Do not use the welder without grounding the
frame or the case. Do not ground to pipelines
carrying gases of flammable liquids. Be sure the
conductors can safely carry the grounding
current.
Keep all connections clean and tight.
Do not use an electric welder on an engine unless
both the engine's battery cables and alternator
wires are disconnected.
Take
Precautions Against
Electric
Shock.
NEVER work in a damp area without suitable
insulation against shock.
NEVER stand in water or on a wet floor or use wet
gloves when welding.
ALWAYS dry out the work pieces or bench if there
is any evidence of moisture.
OPEN power circuits before inspecting
machines.
ALWAYS turn off the machine when leaving the
work.
* Do Not Weld Near Inflammable Materials.
NEVER weld in or near EXPLOSIVE AT-
MOSPHERES.
Clean any container that has held combustible or
flammable materials by approved or prescribed
methods. A very small amount of residual gas or
liquid can cause a serious explosion. When the
contents of the container is unknown, use an
explosimeter.
Use carbon dioxide or nitrogen to ventilate a
container. NEVER USE OXYGEN.
When the container has held a gas or liquid that
readily dissolves in water, perform the following:
1.
Flush the container several times with water
and a wetting agent
(e.g.,
a low powered
detergent). Then, fill with as much water as the
work permits.
2.
Provide a vent or opening in the container to
allow the release of air pressure.
When the container has held a gas or liquid that
does not readily dissolve in water, proceed as
follows:
1.
Clean the container with steam or a cleaning
agent and purge all air with a gas such as carbon
dioxide or nitrogen.
2.
Use steam to clean out light material.
3. To clean out heavy grease or oil, use a strong
caustic soda solution.
4.
Before welding on the container, PURGE ALL
AIR with a gas such as carbon dioxide or nitrogen.
Wear goggles and gloves when cleaning with
steam or caustic soda.
Always clean the container in a well ventilated
area,
away from any open flame.
When scraping or hammering heavy sludge or
scale,
use a WET, spark resistant
tool.
Always keep head and arms as far away from the
work as possible.
• Never Weld On Hollow (Cored)
Castings
That
Have Not
Been
Properly Vented.
• Never
Pick
Up Hot
Metal
With
Bare
Hands.
• Do Not Weld In Confined
Areas
Without
Adequate
Ventilation.
