ARC RAYS -- Can injure eyes and burn skin.
The arc, likethe sun, emitsultraviolet (UV) andother radiation andcan 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.
eyes when welding or watching.
2.Wear approved safety glasses with side shields under your helmet.
3.-
tion. Warn bystanders not to watch the arc and not to expose themselves to the rays
of the electric-arc or hot metal.
4.
apron may also be desirable as protection against radiated heat and sparks.
5.
partition or curtains.
6.Use goggles over safety glasses when chipping slag or grinding. Chipped slag may
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 conned 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.
FIRES AND EXPLOSIONS -- Heat from ames and arcs can start res. Hot
slag or sparks can also cause res and explosions. Therefore:
1.
2.Remove all combustible materials well away from the work area or cover the materials
sawdust, liquid and gas fuels, solvents, paints and coatings paper, etc.
3.
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
-
mable or toxic vapors. Do not do hot work on closed containers, they may explode.
5.-
6.Do not use equipment beyond its ratings. For example, an overloaded welding cable
7.After completing operations, inspect the work area to make certain there are no hot
!CAUTION
This product is solely intended for arc welding.
!CAUTION
ClassAequipment is not intended for use in residential locations
where the electrical power is provided by the public low-voltage
electromagnetic compatibility of class A equipment in those lo-
cations, due to conducted as well as radiated disturbances.
NOTE!
Dispose of electronic equipment at the recycling facility!
In observance of European Directive 2012/19/EC on Waste Electri-
cal and Electronic Equipment and its implementation in accordance
with national law, electrical and/or electronic equipment that has
reached the end of its life must be disposed of at a recycling facility.
As the person responsible for the equipment, it is your responsibility to obtain information
on approved collection stations.
For further information contact the nearest ESAB dealer.
2. INSTRUCTION

• 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 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.

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
Leave the contaminated area immediately and if needed seek medical advice if:
• The Manufacturer’s Minimum Design Flow (MMDF) warning alarm sounds.
•
• Dizziness or distress occurs.
• Any part of the system becomes damaged.
•
• Contaminant can be smelled or tasted inside the head unit
• In the unlikely event of an allergic reaction to the air-helmet materials
3. APPROVALS
The system complies with the requirements of PPE Regulation 2016/425 and European
Standard EN 12941: 1998+A2:2008 class TH3 P R S L. The Respiratory System is de-
equipment can be used in any environment that requires a class TH3P breathing protection
device. It protects against particulate contamination.
All components used in Respiratory System must be ESAB approved parts and must be
used in accordance with the instructions in this manual.
1. The approval is valid only if the product is used together with approved
parts and lters.
2. Only listed particulate lter and pre-lter can be used together with this sys-
tem. Filters from other manufacturers shouldn’t be used under any circumstances,
and voids both the certication and warranty.
4. WARNING AND LIMITATIONS TO USE
Before each use, inspect the Respiratory System for damage and verify it operates properly.
verify it is providing an adequate volume of air.
Continuously wear the Respiratory System and do not remove the helmet or turn OFF the
-
tion of CO2 and oxygen level in the helmet will fall, resulting in little or no protection.
If you are not sure about the concentration of pollution, or about equipment performance,
consult an industrial safety engineer or EHS manager.
Users of this respiratory device should be properly in its correct wearing and use.
5. UNPACKING/ASSEMBLY
