Introduction

• When used in accordance with these instructions, CleanAIR® Omnira / Omnira air is designed to protect the user´s eyes and face against high-speed particles. It is a multipurpose protective face shield that can be easily converted to a professional welding helmet with flip-up welding shield CleanAIR® Omnira COMBI /Omnira COMBI air.
• CleanAIR® Omnira COMBI / Omnira COMBI air is designed to protect the user´s eyes and face from harmful radiation including visible light, ultra-vi-olet (UV), infra-red (IR) radiation and hot sparks, and spatters resulting from arc welding and cutting
• applications such as MIG, MAG, TIG, SMAW, Plasma Arc, Carbon Arc gouging. This welding helmet is not recommended for heavy-duty overhead welding applications, laser welding or laser cutting applications.
• CleanAIR® Omnira air / Omnira COMBI air is adapted for use with powered air-purifying respirators (hereinafter PAPR) CleanAIR® or with continuous flow compressed air breathing apparatuses (hereinafter „compressed air system“) CleanAIR® and thus
• provides protection of the respiratory tract. CleanAIR® is a system of personal respiratory protection based on the principle of overpressure of filtered air in the breathing zone. The respiration is placed on the wearer’s belt and filtrates the air which is taken in
• from the surrounding environment and then delivers it through the air duct into the protective helmet. The overpressure prevents contaminants from entering the breathing zone. This mild overpressure at the same time ensures the wearer’s comfort, even
• with long-term use, as the wearer does not have to struggle in breathing to overcome the resistance of the filter.

Before you start working

CleanAIR® Omnira COMBI / Omnira COMBI air

• Ensure that the helmet is correctly assembled and that it completely blocks any accidental light. In the front, light may enter the helmet only through the viewing area of the welding filter. Ensure that the welding shield is parked in the lower position before you start welding. Adjust the headgear to ensure maximum comfort and to provide the largest field of vision.
• Check the prescribed shade level for your welding application and adjust your auto-darkening filter accordingly (select the appropriate passive welding filter) – see the table with recommended shade levels).
• Inspect that the main protective visor is undamaged, clean and installed correctly. Replace the visor immediately, if it is damaged, or if spatter or scratches reduce vision. Inspect that the protection plates are undamaged, clean and installed correctly. Replace the plate immediately, if it is damaged, or if spatter or scratches reduce vision. Inspect that the welding filter is undamaged and clean. The damaged welding filter impairs protection and visibility and must be replaced immediately. Inspect that the welding helmets and headgear are undamaged.

CleanAIR® Omnira / Omnira air

• Ensure that the protective faceshield is correctly assembled. Adjust the headgear to ensure maximum comfort and to provide the largest field of vision. Inspect that the protective visor is undamaged, clean and installed correctly. Replace the visor immediatelly, if it is damaged, or if spatter or scratches reduce vision.

WARNING – CleanAIR® Omnira COMBI / Omnira COMBI air, CleanAIR® Omnira / Omnira air

•  Do not use CleanAIR® Omnira COMBI / Omnira COMBI air for welding if the welding shield is in the upper position! The clear visor doesn´t pro-tect against harmful radiation.
• Use only original CleanAIR® / AerTEC™ spare parts and consumables. In case of doubt, please contact your authorized distributor. The use of substitute components or any modifications not specified in this manual might impair protection and may invalidate claims under the warranty or cause the product to be non-compliant with protection classifications and relevant standards and certificates.
• Never place the helmet or the auto-darkening welding filter on a hot surface.
• Scratched or damaged protection visors or plates should be regularly replaced by original CleanAIR® ones. Before using a new visor or pro-tection plate, make sure to remove any additional protection foil from both sides.
• Do not use tempered mineral filters without suitable protection foils.
• Replace the protection plate immediately, if it is damaged, or if spatter or scratches reduce vision.
• Do not expose the auto-darkening welding filter to liquids and protect it from dirt
• Materials that may come into contact with the wearer’s skin could cause allergic reactions to susceptible individuals.
• Welding helmet worn over standard ophthalmic spectacles may transmit impact, thus creating a hazard to the wearer

Limitations on use of CleanAIR® Omnira COMBI air / Omnira air Never use the helmet in the following environments and under the following conditions:

• If oxygen concentration in the environment is lower than 17%.
• In oxygen-enriched environments.
• In explosive ambiance.
• In environments that represent an immediate threat to life and health.

The helmet does not protect against hard shocks, explosions or corrosive substances. Do not use in environments where the user does not know the type of contamination or its concentration. Do not use it when the powered air purifying respirator is turned off or when the compressed air inlet is closed! In this case, the respiratory system gives little or no respiratory protection. Also, there is a risk of a high concentration of carbon dioxide (CO2) building up and a risk of oxygen deficiency occurring inside the helmet. Move to a secure location and take appropriate measures when any of the following problems occur while using the helmet:

• If the PAPR or the compressed air system cease to operate for any reason whatsoever, the user must leave the contaminated workplace without delay.
• If you experience stench or irritation or an unpleasant taste while breathing.
• If you feel unwell or if you experience nausea.
  Filters designed for capturing solid and liquid particles (particle filters) do not protect the user against any gases. Filters designed for capturing gas- es do not protect the user against any particles. In the workplace contami- nated by both types of pollution, combined filters must be used.

Sensitivity guideline

• Sensitivity settings is used to tell the auto-darkening lens how sensitively it should respond to the welding arc and interferences. Due to different working environments and properties of welding processes, adjustments may be required. Sensitivity should be
• determined by the following factors: applications, amperage of applications, interference:
• Applications (Stable arc, such as DC TIG, non-stable arc, MMA/STICK, MIG, Plasma, etc.)
• Amperage of Applications (Extreme low, low-medium, medium-high)
• Interference (Direct strong sunlight, strong fluorescent lights, neighbor welding arc etc.)

Sensitivity settings

• 1~2 The least sensitive setting – for high current non-stable arc applications, in environments with strong interferences.
• 3~4 For low current non-stable arc applications, in environments with strong interferences.
• 5~6 Default setting – used for most types of welding, indoors and outdoors under normal ambient lights and/or low interferences.
• 7~8 For low current welding or stable arc applications, such as DC TIG.
• 9 The most sensitive setting is suitable for very low current TIG welding or welding where part of the arc is obscured from view. The lens is very sensitive and may become dark due to strong ambient lights or interferences.
• When not sure which number to use, therule of thumb is to set higher number firstly, reduce one by one if interferences exists until the lens is not interfered.
• For recommended shade level selection please see table (*PICTURE 16)
