INTRODUCTION
Make sure this manual is carefully read and
understood by the welder, and by the mainte-
nance and technical workers.
PERSONAL PROTECTION
Welding processes of any kind can be dan-
gerous 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,
clothing, without pockets or turned up trou-
sers, 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 si-
des. Keep protective lens clean and replace
them when broken, cracked or spattered. Po-
sition 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 protec-
tion 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 throu-
gh a mobile hood or through a built-in system
on the workbench that provides exhaust ven-
tilation from the sides, the front and below,
but not from above the bench so as to avoid
raising dust and fumes. Local exhaust venti-
lation must be provided together with ade-
quate general ventilation and air circulation,
particularly when work is done in a confined
space.
•
Welding process must be performed on me-
tal surfaces thoroughly cleaned from rust or
paint, to avoid production of harmful fumes.
The parts degreased with a solvent must be
dried before welding.
•
Be very carefull when welding any me-
tals which may contain one or more of the
follwing:
Antimony
Beryllium
Manganese
Selenium
Cadmium
Copper
Silver
Barium
Lead
Nickel
SAFETY INFORMATION
non-flammable

Cobalt
Arsenic
Mercury
Chromium
Vanadium
•
Remove all chlorinated solvents from the
welding area before welding. Certain chlo-
rinated 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. In-
spect it regularly 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 accu-
mulation 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
other insulating materials to move cables, if
necessary away from the person.
•
Wear dry gloves and clothing. Insulate
yourself from the work piece or other parts of
the welding circuit.
•
Make sure the main line is properly grounded.
•
Do not coil the torch or the ground cables
around your body.
•
Never touch or come in physical contact with
any part of the input current circuit and wel-
ding current circuit.
Electric warning:
•
Repair or replace all worn or damaged parts.
•
Extra care must be taken when working in
moist or damp areas.
•
Install and maintain equipment according to
local regulations.
•
Disconnect power supply before performing
any service or repair.
•
Should you feel the slightest electrical shock,
stop any welding immediately and do not use
the welder until the fault has been found and
corrected.
