12. Protect the auto-darkening (ADF) filter from contact with liquid and dirt.
• Clean the (ADF) surface regularly by using clean water and a lint-free or microfiber
cloth; do not use strong cleaning solutions. Always keep the sensors and solar
cells clean using a clean lint-free tissue or microfiber cloth.
• Regularly replace a cracked/scratched/pitted front cover lens. Avoid setting the helmet
down directly on the cover lens to avoid premature damage to the cover lens.
• The materials which may come into contact with the wearer’s skin can cause
allergic reactions in some circumstances.
• The Auto-Darkening filter shall only be used in conjunction with the inner cover lens.
ARC RAYS - Can injure eyes and burn skin
The arc, like the sun, emits ultraviolet (UV) and other radiation and
can injure skin and eyes. Hot metal can cause burns. Training in the
proper use of the processes and equipment is essential to prevent
accidents. Therefore:
1. Wear a welding helmet fitted with a proper shade of filter to protect your face and eyes
when welding or watching.
2. Wear approved safety glasses with side shields under your helmet.
3. Before welding, adjust the auto-darkening filter (ADF) lens sensitivity to meet the
application. Warn bystanders not to watch the arc and not to expose themselves to the
rays of the electric-arc or hot metal.
4. Wear protective clothing made from durable, flame-resistant material. A flameproof
apron may also be desirable as protection against radiated heat and sparks.
5. Protect other personnel from arc rays and hot sparks with a suitable non-flammable
partition or curtains.
6. Use goggles or face shield over safety glasses when chipping slag or grinding.
Chipped slag may be hot and can fly far. Bystanders should also wear goggles over
safety glasses.
NOISE - Excessive noise can damage hearing
Protect your ears. Wear approved ear protection if noise level is high.
FUMES AND GASES
Fumes and gases can cause discomfort or harm, particularly in
confined spaces. Shielding gases can cause asphyxiation. Therefore:
1. Keep your head out of the fumes. Do not breathe the fumes and gases.
2. Always provide adequate ventilation in the work area by natural or mechanical means.
Do not weld, cut or gouge on materials such as galvanized steel, stainless steel,
copper, zinc, lead beryllium or cadmium unless positive mechanical ventilation is
provided. Do not breathe fumes from these materials.
3. Do not operate near degreasing and spraying operations. The heat or arc can react
with chlorinated hydrocarbon vapors to form phosgene, a highly toxic gas and other
irritant gases.
4. If you develop momentary eye, nose or throat irritation while operating, this is an
indication that ventilation is not adequate. Stop work and take necessary steps to
improve ventilation in the work area. Do not continue to operate if physical discomfort
persists.
5. Refer to ANSI/ASC Standard Z49.1 for specific ventilation recommendations.
