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 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 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.
1.5
NOISE
Noise can cause permanent hearing loss. Welding processes can cause noise levels that exceed safe limits. You must protect your ears from loud
moise to prevent permanent loss of hearing.
√√√√√
To protect your hearing from loud noise, wear protective ear plugs and/or ear muffs.
√√√√√
Noise levels should be measured to be sure the decibels (sound) do not exceed safe levels.
1.1
INTRODUCTION
Make sure this manual is carefully read and understood by the welder, and by the maintenance and technical workers.
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 obeserved.
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. 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 welding.
√√√√√
Be very carefull when welding any metals which may contain one or more of the follwing:
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.
1.0 SAFETY INFORMATION
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;
1.6
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, computers or other control systems near the unit.
√√√√√
People with pace-maker or hearing-prosthesis should keep far from the power source.
