INTRODUCTION
Make sure this manual is carefully read and understood by the welder, and by the maintenance and
technical workers.
PERSONAL PROTECTION
Welding processes of any kind can be dangerous not only to the operator but to any person situated near
the equipment, if safety and operating rules are not strictly observed.
Arc rays can injure your eyes and burn your skin. The welding arc produces very bright ultra
violet and infra red light. These arc rays will damage your eyes and burn your skin if you are
not properly protected.
•
Wear closed, non-flammable protective clothing, without pockets or turned up trousers, gloves and
shoes with insulating sole and steel toe. Avoid oily greasy clothing.
•
Wear a non-flammable welding helmet with appropriate filter lenses designed so as to shield the
neck and the face, also on the sides. Keep protective lens clean and replace them when broken,
cracked or spattered. Position a transparent glass between lens and welding area.
•
Weld in a closed area that does not open into other working areas.
•
Never look at the arc without correct protection to the eyes. Wear safety glasses with the side shields
to protect from flying particles.
Gases and fumes produced during the welding process can be dangerous and hazardous to
your health.
•
Adequate local exhaust ventilation must be used in the area. It should be provided through a mobile
hood or through a built-in system on the workbench that provides exhaust ventilation from the sides,
the front and below, but not from above the bench so as to avoid raising dust and fumes. Local
exhaust ventilation must be provided together with adequate general ventilation and air circulation,
particularly when work is done in a confined space.
•
Welding process must be performed on metal surfaces thoroughly cleaned from rust or paint, to
avoid production of harmful fumes. The parts degreased with a solvent must be dried before wel-
ding.
•
Be very carefull when welding any metals which may contain one or more of the follwing:
Antimony
Cadmium
Nickel
•
Remove all chlorinated solvents from the welding area before welding. Certain chlorinated solvents
decompose when exposed to ultraviolet radiation to form phosgene gas (nerve gas).
FIRE PREVENTION
Fire and explosion can be caused by hot slag, sparks or the welding arc.
•
Keep an approved fire extinguisher of the proper size and type in the working area. Inspect it regu-
larly to ensure that it is in proper working order;
•
Remove all combustible materials from the working area. If you can not remove them, protect them
with fire-proof covers;
•
Ventilate welding work areas adequately. Maintain sufficient air flow to prevent accumulation of
explosive or toxic concentrations of gases;
•
Do not weld on containers that may have held combustibles;
•
Always check welding area to make sure it is free of sparks, slag or glowing metal and flames;
•
The work area must have a fireproof floor;
ELECTRIC SHOCK
WARNING: ELECTRIC SHOCK CAN KILL!
•
A person qualified in First Aid techniques should always be present in the working area; If a person is
found unconscious and electric shock is suspected, do not touch the person if she or he is in contact
with cable or electric wires. Disconnect power from the machine, then use First Aid. Use dry wood or
