Special Notes
Arc: Use an arc welding mask to protect your eyes and skin
from sparks and the rays of the arc, pay special attention to
the filter glass, which must be conformable to the national
standard.
• Use clothing made from durable flame-resistant material or
sailcloth to protect your skin from hurting by the arc rays.
• Remind other nearby personnel before working lest arc rays hurt
them by accident.
Fumes and Gases: Welding may produce fumes and gases
hazardous to health. Avoid breathing these fumes and gases.
While working in limited room, use enough ventilation and/or
exhaust to keep fumes and gases away from the breathing
zone, or use the respirator. Do not weld at the same time when using of
degreasing, cleaning or spraying operations. The heat and rays of the arc
can react with these gases to form phosgene, a highly toxic gas,
• Some protective gases used in welding might displace the oxygen in
the air, and can lead to hurt or even death.
• Read and understand the manufacturer’s instructions for this
equipment, and validate the health certification of consumptive
materials, make sure they are innocuous.
Spatter: Spatter can cause fire or explosion.
• Remove fire hazards from the welding area. Remember that
spatter from welding can easily go through small cracks and
touch fire hazards. Protect all kinds of lines going though
welding area, including hydraulic lines in the wild.
• Where compressed gases are to be used in the field, special
precautions should be used to prevent explosion.
• When welding stops, make certain that no live part is touching
the work piece or the work stage. Accidental contact can create a fire
hazard.
• Do not weld containers or lines, which are not proved to be
innocuous.
• It is very dangerous to heat, cut or weld tanks or containers at entry
holes. Does not start work until the proper steps have been taken to
insure that there is no flammable or toxic gas.
• Spatter might cause burn. Wear leather gloves, heavy shirt, cuffless
trousers, high shoes and a cap over your hair to prevent from burning
by spatter. Wear the ear shield when performing sideways or face up
welding. Always wear safety glasses with side shields when being in a
welding area.
• The welding cables should be as close to the welding area as
possible, and the short, the better. Avoid welding cables going through
the building framework, lifting chains, AC or DC cables of other welding
machines and appliances. The welding current is strong enough to
damage them while having short circuit with them.
Cylinder: Damage of it might cause explosion.
• Make sure that the gas in the storage cylinder is qualified
for welding, and the decompression flow-meter, the adapter
and the pipe are all in good condition.
• Make sure that the installation of cylinder is by the wall and bundled
tightly by a chain.
• Be sure to put the cylinder in the working space with no crash or
shake, and far from welding area.
• It is forbidden to touch cylinder with the welding clamp or the work
cables.
• Avoid facing the cylinder while installing the decompression flowmeter or the gasometer.
• When not working, please tighten the valve.
Power: (For electrically powered welding and cutting
equipment) Turn off input power before installation,
maintenances and repair, so that avoid accident.
• MetalCut welding equipment is Ι class safeguard equipment;
please install the equipment in accordance with the manufacturer’s
recommendations by specific persons.
• Ground the equipment perfectly in accordance with the
manufacturer’s recommendations.
Power: (For engine driven welding and cutting equipment)
• Work in ventilated place or outdoors.
