Important
Please read and remember the following instructions before use to assure your own safety. If you
have any questions, please contact the manufacturer or your distributor. Keep the manual for future
reference. The welding helmet should be used only for the purposes listed in this manual.
1. Introduction
There are two main variants of product - welding helmet AerTEC™ YOGA and welding helmet CA-27 YOGA.
Welding helmet AerTEC™ YOGA is the basic variant of the product, certified according to EN 166:2001 and
EN 175:1997-08. It provides protection against harmful ultraviolet / infrared radiation, welding spatters
and high speed particles (indicated: B). Welding helmet CA-27 YOGA represents the improved version
of welding helmet AerTEC™ YOGA and is adapted for use with powered air purifying respirators (he-
reinafter PAPR) CleanAIR® or with continuous flow compressed air line breathing apparatuses (herei-
nafter "compressed air systems CleanAIR®) and thus provides protection of the respiratory tract. The
variant CA-27 YOGA is additionally certified according to EN 12941:1998+A2:2008 and EN 14594:2005.
CleanAIR® is a system of personal respiratory protection based on the principle of overpressure of filte-
red air in the breathing zone. The respirator 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 airduct into the protective
helmet. The overpressure prevents contaminants from entering the breathing zone. This mild overpre-
ssure at the same time ensures the wearer's comfort, even with long-term use, as the wearer does
not have to struggle in their breathing to overcome the resistance of the filter.

2. Limitations on use

Limitations for welding helmets AerTEC™ YOGA and CA-27 YOGA
1.
If work requires a protection against fast flying objects at extreme temperatures make sure that
visor has an marking T on it.
2. Material of the helmet can cause allergic reactions to sensitive person.
3. Do not use tempered mineral filters without suitable protection foils.
4. The welding arc damages unprotected eyes!
5. The welding arc may burn unprotected skin!
6. Pay attention to checking the product before use. Do not use, if any part of the system is damaged.
7.
Don't put the welding helmet on hot surface.
8. Replace protection filter immediately, if it is damaged, or if spatter or scratches reduce vision.
Additional limitations for CA-27 YOGA version
1.
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 ambience.
• In environments where the user lacks knowledge about the kind of dangerous substance and
its concentration.
• In environments that represent an immediate threat to the life and health.
• If you are not sure, that shade number of your welding filter lens is suitable for your work.
• 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 when the powered air purifying respirator is turned off or when the compressed air
inlet is closed! In this case the respiratory system, incorporating a helmet, gives little or no respi-
ratory protection. Also there is a risk of a high concentration of carbon dioxide (CO
and of oxygen deficiency occurring inside the headpiece.

2. 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.
3. Use certified original filters designed for your powered air purifying respirator only. Replace filters
every time you detect change of odour in supplied air from the respirator.
4. Filters designed for capturing solid and liquid particles (particle filters) do not protect the user
against any gases. Filters designed for capturing gases do not protect the user against any par-
ticles. In the workplace contaminated with both types of pollution, combined filters must be used.
3. Control and maintenance
AerTEC™ YOGA is a complete welding helmet consisting of the welding shield including auto-darkening
filter and headband. Version CA-27 has additional air distribution. Lifetime of the helmet and visors is
influenced by many factors such as: cold, heat, chemicals, sunlight or incorrect use. The helmet should
be checked on a daily basis of possible damage of its inside or outside structure.
Careful use and correct maintenance of welding helmet enhances operating life and improves your
safety!
Checking before use:
Inspect that the protection plates are undamaged, clean and installed correctly. Replace lens imme-
diately, if it is damaged, or if spatter or scratches reduce vision.
Inspect that the welding filter lens is undamaged and clean. The damaged welding filter lens im-
pairs protection and visibility and must be replaced immediately.
Make sure that the shade number of welding filter lens is appropriate for your work (according to
„6. Filter shade number selection").
Inspect that the welding helmet and headgear are undamaged.
Inspect that welding shield is completely closed when lowered.
Cleaning:
After each work shift, clean the head section, check individual parts, and replace damaged parts.
Cleaning must be performed in a room with sufficient ventilation. Avoid inhalation of harmful dust
settled on individual parts!
For cleaning, use lukewarm water (up to +40 °C) with soap or other non-abrasive detergent, and
a soft brush.
It is prohibited to use cleaning agents with solvents.
After cleaning individual parts with a damp cloth, it is necessary to rub them dry, or let them dry at
room temperature.
It is recommended to use CleanAIR® ®klar-pilot Fluids for caring of the visors and plastic parts.
DO NOT USE DISHWASHER OR DRYER!
DO NOT USE ACETONE OR OTHER CLEANING SOLVENTS!
Grinding / Welding mode selection
Choose between GRIND / WELD mode by switching the mode button. Once GRIND mode is activated,
the shade is fixed in the light state allowing a  clear view. Make sure WELD mode is being enabled
before starting welding.
