1.0 SAFETY INFORMATION
1.1 INTRODUCTION
Make sure this manual is carefully read and understood by the welder and
by the maintenance and technical operators.
1.2 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 process 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 tur-
ned up trousers, gloves and shoes with insulating sole. Avoid oily grea-
sy 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 always 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 voltaic arc without the 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 adequ-
ate general ventilation and air circulation, particularly when work is
done in a confined space.
• Welding process must be performed on metal coatings thoroughly clea-
ned from layers of rust or paint, to avoid production of harmful fumes.
The parts degreased with a solvent must be dried before welding.
• Be very careful when welding any metals, which may contain one or
more of the following:
Antimony • Beryllium • Cobalt • Manganese • Selenium • Arsenic •
Cadmium • Copper • Mercury • Silver • Barium • Chromium • Lead •
Nickel • Vanadium
• Remove all chlorinated solvents from the welding area before welding.
Certain chlorinated solvents decompose when exposed to ultraviolet
radiation to form phosgene gas.
1.3 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 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 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;
1.4 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 com-
mands. 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 mains line is properly grounded.
• Do not coil the torch or the earth cables around your body.
• Never touch or come in physical contact with any part of the input cur-
rent circuit and welding current circuit.
• 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 with local regulations.
• Disconnect power supply before performing any service or repair.
• Should you feel the slightest electrical shock, stop any welding immedi-
ately and do not use the welder until the fault has been found and solved.
1.5 NOISE
Noise can cause permanent hearing loss. Welding processes can cause
noise levels to exceed safe limits. You must protect your ears from loud
noise to prevent permanent loss of hearing.
• To protect your hearing from loud noise, wear protective earplugs and/or
earmuffs.
• Noise levels should be measured to be sure the decibels (sound) do not
exceed safe levels.
1.6 ELECTROMAGNETIC COMPATIBILITY
Before installing your welder, carry out an inspection of the surrounding
area, observing the following guidelines:
• Make sure that there are no other power supply cables, control lines,
telephone leads or other equipment near the unit.
• Make sure that there are no radio receivers, television appliances, com-
puters or other control systems.
•
People with pacemaker or hearing-prosthesis should keep far from
the power source.
! In particular cases special protection measures may be required.
Interference can be reduced following these suggestions:
• If there is interference in the power source line, an E.M.T. filter can be
mounted between the power supply and the power source;
• The output cables of the power source should be shortened, kept toget-
her and connected to ground;
• After the maintenance all the panels of the power source must be secu-
rely fastened in place.
1.7 PROTECTIVE WELDING GASES
Shielding gas cylinders contain gas under high pressure. If damaged, a
cylinder can explode. Treat them carefully.
• These welders are using only inert or non-flammable gases for welding
arc protection. It is important to choose the appropriate gas for the type
of welding to perform;
• Do not use gas from unidentified cylinders or damaged cylinders;
• Do not connect the cylinder directly to the welder, use a pressure regulator;
• Make sure the pressure regulator and the gauges function properly;
• Do not lubricate the regulator with oil or grease;
• Each regulator is designed for use with a specific gas. Make sure the
regulator is designed for the protective gas being used;
• Make sure that the cylinder is safely secured tightly to the welder with
the chain provided.
• Never expose cylinders to excessive heat, sparks, slag or flame;
• Make sure that the gas hose is always in good condition;
• Keep the gas hose away from the working area.
2.0 INSTALLATION RECOMMENDATIONS
2.1 LOCATION
Be sure to locate the welder according to the following guidelines:
• In areas, free from moisture and dust;
• Ambient temperature between 0° to 40°C;
• In areas, free from oil, steam and corrosive gases;
• In areas, not subjected to abnormal vibration or shock;
• In areas, not exposed to direct sunlight or rain;
• Place at a distance of 300mm or more from walls or similar that could
restrict natural airflow for cooling.
2.2 VENTILATION
Since the inhalation of welding fumes can be harmful, ensure that the wel-
ding area is effectively ventilated.
