Arc rays from the welding process produce intense visible and invisible ultraviolet and infrared rays that
can burn eyes and skin.
• Always wear a welding helmet with correct shade of filter lens and suitable protective clothing
including welding gloves whilst the welding operation is performed.
• Measures should be taken to protect people in or near the surrounding working area.
Use protective screens or barriers to protect others from flash,glare and sparks; warn others not to
watch the arc.
Welding can cause fire explosive, 
Welding on closed containers, such as tanks,drums, or pipes, can cause them to explode. Flying sparks
from the welding arc, hot work piece, and hot equipment can cause fires and burns. Accidental contact of
electrode to metal objects can cause sparks, explosion, overheating, or fire. Check and be sure the area
is safe before doing any welding.
• The welding sparks & spatter may cause fire, therefore remove any flammable materials well away
from the working area. Cover flammable materials and containers with approved covers if unable to
be moved from the welding area.
• Do not weld on closed containers such as tanks, drums, or pipes, unless they are properly prepared
according to the required Safety Standards to insure that flammable or toxic vapors and substances are
totally removed, these can cause an explosion even though the vessel has been “cleaned”.
Vent hollow castings or containers before heating, cutting or welding. They may explode.
• Do not weld where the atmosphere may contain flammable dust, gas, or liquid vapours (such as petrol)
• Have a fire extinguisher nearby and know how to use it. Be alert that welding sparks and hot materials
from welding can easily go through small cracks and openings to adjacent areas. Be aware that welding
on a ceiling, floor, bulkhead, or partition can cause fire on the hidden side.
FUMES and gases can be hazardous.
Fumes and gases are dangerous. Smoke and gas generated whilst welding or cutting can be harmful
to people’s health. Welding produces fumes and gases. Breathing these fumes and gases can be
hazardous to your health.
• Do not breathe the smoke and gas generated whilst welding or cutting, keep your head out of the
fumes
• Keep the working area well ventilated, use fume extraction or ventilation to remove welding fumes and gases.
• In confined or heavy fume environments always wear an approved air-supplied respirator.
Welding fumes and gases can displace air and lower the oxygen level causing injury or death. Be sure the
breathing air is safe.
• Do not weld in locations near de-greasing, cleaning, or spraying operations. The heat and rays of the arc
can react with vapours to form highly toxic and irritating gases.
• Materials such as galvanized, lead, or cadmium plated steel, contain elements that can give off toxic
fumes when welded. Do not weld these materials unless the area is very well ventilated, and or wearing
an air supplied respirator.

7
Flying metal can injure eyes
• Welding, chipping, wire brushing, and grinding cause sparks, flying metal as welds cool,
they can throw off slag.
• Wear approved safety glasses with side shields even under your welding helmet.
HOT parts can cause severe burns.
• Allow cooling period before handling.
• Wear protective gloves and clothing when working on a hot engine.
• Do not touch hot engine parts or just-welded parts with bare hands.
Noise can damage hearing
• Noise from some processes and equipment can damage the hearing.
• Wear approved ear protection if noise level is high.
Electronic magnetic fields
MAGNETIC FIELDS can affect Implanted Medical Devices.
• Wearers of Pacemakers and other Implanted Medical Devices should keep away.
• Implanted Medical Device wearers should consult their doctor and the device manufacturer
before going near any electric welding, cutting or heating operation.

Shielding gas cylinders contain gas under high pressure. If damaged, a cylinder can explode. Because
gas cylinders are normally part of the welding process, be sure to treat them carefully. CYLINDERS can
explode if damaged.
• Protect gas cylinders from excessive heat, mechanical shocks, physical damage, slag, open flames, sparks,
and arcs.
• Insure cylinders are held secure and upright to prevent tipping or falling over.
• Never allow the welding electrode or earth clamp to touch the gas cylinder, do not drape welding cables over the
cylinder.
• Never weld on a pressurised gas cylinder, it will explode and kill you.
• Open the cylinder valve slowly and turn your face away from the cylinder outlet valve and gas regulator.

Position
Place the machine on a level surface at a distance of at least 1 meter from buildings or other plants.
Maximum leaning of the machine (in case of unlevel surface).
Check that the air gets rotated completely and the hot air sent out does not come back inside the set so as to cause a
dangerous increase of the temperature.
Make sure that the machine does not move during its operation: secure it properly so that is cannot move during
operation.
Before moving check that the engine is off, and all cables are disconnected.

Installation and movement
Installation and advice before use:
The operator of the welder is responsible for the safety of the people who work with the welder and for those in the
vicinity. The safety measures must satisfy the rules and regulations for engine driven welders. The information given
below is in addition to the local safety norms:
Check the work area for possible electromagnetic problems, taking into account the following indications.
1. Telephone wirings and /or communications.
2. Radio and television receptors and transmitters.
3. Computers and other checking devices.
4. Critical devices for safety and /or for industrial checks.
5. People who, for instance, use pace-maker, hearing-aids.
6. Devices used for rating and measuring.
7. Ensure that other used devices are compatible.
Make sure that the area is safe before starting any welding operation
Do not touch any bare wires, leads or contacts as they may be live and there is danger of electric shock which can
cause death or serious burns. The electrode and welding cables, etc. Are live when the unit is operating.
• do not touch any electrical parts or the electrode while standing in water or with wet hands ,feet or clothes
• Insulate yourself from the work surface while welding. Use insulating materials to avoid physical contact with the
work surface and the floor.
• Always wear dry, insulating glovers, without holes, and body protection.
• Do not wind cables around the body
• Use ear protection if the noise is high.
• Keep flammable material away from the welding area.
• Do not weld on containers which contain flammable material.
• Do not weld near refueling areas.
• Do not weld on easily flammable surfaces.
• Do not use the welder to defrost (thaw) pipes.
• Remove the electrode from the electrode holder, when not welding.
• Avoid inhaling fumes by providing a ventilation system or, if not possible ,use an approved air breather
• Do not work in closed areas where there is no fresh air flow
• Protect face and eyes (protective mask with suitable dark lens and side screens) ears and body
(non-flammable protective clothes)

19
Diesel engines
Use in open space, air swept or vent exhaust gases far from the work area
Movement
Always securely fasten welding generator onto transport vehicle or trailer and comply with all transport rules and other
applicable codes.
