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 (hereinafter PAPR) CleanAIR® or with continuous flow compressed air line breathing apparatuses (hereinafter “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 filtered 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 overpressure 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.
Limitations on use
Limitations for welding helmets AerTEC™ YOGA and CA-27 YOGA
- If work requires a protection against fast flying objects at extreme temperatures make sure that visor has an marking T on it.
- Material of the helmet can cause allergic reactions to sensitive person.
- Do not use tempered mineral filters without suitable protection foils.
- The welding arc damages unprotected eyes!
- The welding arc may burn unprotected skin!
- Pay attention to checking the product before use. Do not use, if any part of the system is damaged.
- Don’t put the welding helmet on hot surface.
- Replace protection filter immediately, if it is damaged, or if spatter or scratches reduce vision.
Additional limitations for CA-27 YOGA version
- 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 respiratory protection. Also there is a risk of a high concentration of carbon dioxide (CO2) building up and of oxygen deficiency occurring inside the headpiece.
- 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.
- 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.
- 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 particles. In the workplace contaminated with both types of pollution, combined filters must be used.
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 immediately, 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 impairs 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. -
Shade level selection
Adjust the shade level by rotating the SHADE knob. To select the proper shade level, please follow the “Filter shade selection” table. -
Delay time adjustment
Delay time can be adjusted with the DELAY knob, affecting the time for which the ADF stays darkened after the arc extinguishing. The MIN / MAX values correspond to 0,1 – 1,0 s. -
Sensitivity adjustment
Sensitivity setting affects the intensity of light that activates darkening of the filter. darkening of the filter. It’s recommended to start welding with sensitivity set to HIGH first and then to slowly reduce sensitivity to the point where ADF reacts only to the welding arc, ignoring the ambient light. -
Battery replacement
When the LOW BATTERY led starts glowing, replace the battery with the proper CR2032 equivalent. ADF holder removal (see Pictorial annex on the cover)- release the locker that secures the ADF
- remove the ADF holder from its position
- for putting the ADF holder back, firstly place the plastic pins in the upper part of the holder to its original place and then fasten the locker
-
Inner protection plate replacement (see Pictorial annex on the cover)
- put your finger into the hole in the middle of the top of the inner protection plate
- pull away the protection plate with your finger, bend it and remove it from the ADF
- insert the new inner protection plate back by pushing in two edges first, bending the foil over your finger and snapping the other two edges into the pins
-
ADF replacement (see Pictorial annex on the cover)
- remove the ADF holder (see ADF holder removal)
- stretch the opposite sides of the ADF holder while pulling the ADF out of the holder
- place the new ADF
- insert the ADF holder back into the helmet
-
Outer protection plate replacement (see Pictorial annex on the cover)
- remove the ADF holder (see ADF holder removal)
- change the outer protection plate
- place the ADF holder back
Headband adjustments
- Height adjustment for headband: Adjust the headband height so, that the band part circulating the head is positioned relatively low. This way welding helmet stays well on the head. The padding should be a little above the eyebrows. Height can be adjusted from the top of the head gear.
- Adjustment of welding helmet angle: Adjust the welding helmet angle in regard to your face so that the lower edge of welding helmet is positioned near your chest in the welding position. This way the welding helmet provides the best protection.
- Tension adjustment of head harness: Adjust the band tightness by rotating the adjusting wheel positioned in the back of the band.
- Tension adjustment of welding helmet: Adjust the tightness of welding helmet in regard to head harness by rotating the two thumb screws on the sides. Adjust the tightness of helmet so, that the high raised helmet stays up, but goes down when you nod your head. If the helmet strikes against your chest when falling, the adjustment is too loose or the helmet angle has been adjusted too near your chest from the limiter.
- Distance adjustment: Adjusting the distance between the face and the ADF by loosening both outside tension knobs and subsequent moving forward or backward to desired position. Secure the chosen position by tightening the knobs.
Storage and shelf life
Store the welding helmet in a dry and clean place at room temperature, avoid direct sunlight (temperature range from -10 °C to +55 °C with relative humidity between 20 and 95 %). Longterm storage in temperatures above 45 °C can reduce the lifetime of the battery.
