7.5 Radiations
Ultra-violet radiation created by the arc may damage
your eyes and burn your skin. Therefore:
••
••
• Wear proper clothing and helmet.
••
••
• Do not use contact lenses!! The intense heat coming from
the arc may cause them to stick to the cornea.
••
••
• Use masks with grade DIN 10 or DIN 11 safety lenses at the
least.
••
••
•
Protect people in the surrounding welding area.
Remember: the arc may dazzle or damage the eyes. It is
considered dangerous up to a distance of 15 meters (50
feet). Never look at the arc with the naked eye.
••
••
• Prepare the welding area so as to reduce reflection and
transmission of ultra-violet radiation. Paint walls and exposed
surfaces in black to reduce reflection, install sheathings or
curtains to reduce ultra-violet transmissions.
••
••
• Replace mask lenses whenever damaged or broken.
7.6 Electric shock
Electric shock can kill.
All electric shocks are potentially fatal.
••
••
• Do not touch live parts.
••
••
• Insulate yourself from the piece to be cut and from the
ground by wearing insulated gloves and clothing.
••
••
• Keep garments (gloves, shoes, hats, clothing) and body dry.
••
••
• Do not work in humid or wet areas.
••
••
• Avoid touching the piece to be welded.
••
••
• Should you work close to or in a dangerous area, use all
possible precautions.
••
••
• If you should feel even the slightest electric shock sensa-
tion, stop welding immediately. Do not use the machine until
the problem is identified and solved.
••
••
• Always fit an automatic wall switch with adequate power,
possibly close to the machine, allowing you to immediately
switch the machine off in case of an emergency.
••
••
• Frequently inspect the power supply cable.
••
••
• Disconnect power supply cable from mains before replacing
cables or before removing unit covers.
••
••
• Do not use the unit without protection covers.
••
••
• Always replace any damaged parts of the unit, with original
material.
••
••
• Never disconnect unit safety devices.
••
••
• Make sure that the power supply line is equipped with an
efficient earth plug.
••
••
• Make sure that the work bench and the workpiece are
connected to an efficient earth plug.
••
••
• Any maintenance should only be carried out by qualified
personnel aware of the risks due to dangerous voltages
necessary for the operation of the unit.
7.7 Pace maker
••
••
• Magnetic fields from high currents can affect pacemaker
operation. Persons wearing electronic life support equipment
(pacemaker) should consult their doctor before going near arc
welding, gouging or spot welding operations.
7.8.Caution! Welding wire can cause puncture wounds.
••
••
• Do not press gun trigger until instructed to do so.
••
••
• Do not point gun toward any part of the body, other people,
or any metal when threading welding wire.
7.9.Moving parts can cause injury.
Moving parts, such as fans, can cut fingers and hands and
catch loose clothing.
••
••
• Keep all doors, panels, covers, and guards closed and
securely in place.
••
••
• Have only qualified people remove guards or covers for
maintenance and troubleshooting as necessary.
••
••
• Keep hands, hair, loose clothing, and tools away from
moving parts.
••
••
• Reinstall panels or guards and close doors when servicing
is finished and before starting the machine.
7.10 Noise
These power source alone do not produce noise
levels exceeding 80 dB. The welding procedure,
however, may produce noise levels in excess of 80
dB. in which case the machine operator must take the
necessary safety precautions as prescribed by the national
safety regulation.
