Before use, read and understand the instruction manual and follow all labels, employer´s safety practices and Safety Data Sheets (SDSs).

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 lens sensitivity to meet the applica-tion. 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 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 discom-fort persists.
5. Refer to ANSI/ASC Standard Z49.1 for specific ventilation recommendations.

FIRES AND EXPLOSIONS — Heat from flames and arcs can start fires. Hot slag or sparks can also cause fires and explosions. Therefore:

1. Protect yourself and others from flying sparks and hot metal.
2. Remove all combustible materials well away from the work area or cover the materials with a protective non-flammable covering. Combustible materials include wood, cloth, sawdust, liquid and gas fuels, solvents, paints and coatings paper, etc.
3. Hot sparks or hot metal can fall through cracks or crevices in floors or wall openings and cause a hidden smoldering fire or fires on the floor below. Make certain that such openings are protected from hot sparks and metal.
4. Do not weld, cut or perform other hot work until the work piece has been completely cleaned so that there are no substances on the work piece which might produce flam-mable or toxic vapors. Do not do hot work on closed containers, they may explode.
5. Have fire extinguishing equipment handy for instant use, such as a garden hose, wa-ter pail, sand bucket, or portable fire extinguisher. Be sure you are trained in its use.
6. Do not use equipment beyond its ratings. For example, an overloaded welding cable can overheat and create a fire hazard.
7. After completing operations, inspect the work area to make certain there are no hot sparks or hot metal which could cause a later fire. Use fire watchers when necessary.

INSTRUCTION

Use the ESAB PAPR System during welding in unconfined spaces, strictly in accordance with this Instruction manual and the instructions supplied with the corresponding helmets. Do not use the unit:

• When the blower unit is switched OFF. Little or no respiratory protection is to be ex-pected. Rapid buildup of carbon dioxide and depletion of oxygen may occur in the head unit.
• In an atmosphere that poses an immediate health or hygiene hazard and/or has less than 19.5% oxygen content, or contains unknown substances.
• In confined spaces or unventilated areas such as tanks, pipes and canals.
• Near flames and/or sparks.
• In areas with danger of explosion.
• In areas with high winds.
• If the blower unit malfunctions.

To ensure the unit is functioning properly please do not:

• Alter or modify in any way.
• Touch any of the moving parts.
• Allow water or other liquids to enter the impeller chamber, the filter or battery com-partment.

Make sure blower moving parts are not blocked and are free to move.
Do not modify or alter the unit or the particle filter in any way.
Make sure that the approved air-equipped helmet and associated shroud fit perfectly. The efficiency of the system is only sufficient in this case. The protective factor of the complete system is reduced if the seal of the headpiece is not fitted properly, for example if long hair or facial hair is extending into the seal line.
Correct respiratory protection will not be provided if any part of the PAPR and approved air helmet modified in any way.
Position the blower unit in a way that minimizes the risk of the air-equipped welding helmet hose becoming caught up during use.
At elevations above 5,000’ (1500 meters), the PAPR will provide reduced air pressure of at least 5%, with the affects increasing as elevation increases.
Leave the contaminated area immediately and if needed seek medical advice if:

• The Manufacturer’s Minimum Design Flow (MMDF) warning alarm sounds.
• Breathing becomes difficult.
• Dizziness or distress occurs.
• Any part of the system becomes damaged.
• Airflow into the head unit decreases or stops.
• Contaminant can be smelled or tasted inside the head unit
• n the unlikely event of an allergic reaction to the air-helmet materials
