User instructions

Fit the headgear: hold down the buttons on the side mounts and slide the headgear in until it clicks into position. Make sure the black headband faces into the helmet. Adjust the position for a comfortable fit.

Prepare the cover plates: remove the protective film from both sides of the outer and inner cover plates.

Adjust the settings: select welding or grinding mode with switch (1). Set sensitivity using the left-hand knob (2). Adjust the shade using the right-hand knob (3). Select WELD before welding.

Earmuffs (AUDIO): put on the helmet first and adjust the fit. Then put on the earmuffs as usual over the headband.

For long-term storage, select GRIND mode to extend battery life.

These user instructions apply to the AKETEK® AUDIO welding helmet equipped with an auto-darkening filter (ADF). The helmet is designed for electric arc welding (MIG/MAG, MMA, TIG), grinding and plasma cutting. It provides reliable protection against ultraviolet radiation (UV), infrared radiation (IR), visible light, sparks and weld spatter when used according to these instructions.

AKETEK® auto-darkening filters must always be used with the welding helmet. The ADF has two sensors at eye level that react independently to welding arcs and darken the filter. After welding, the filter automatically returns to a light state, allowing the welder to keep the helmet on throughout the work and improving safety, efficiency and weld quality.

These instructions must not be removed except by the user of this equipment. Current instructions are available at www.aketek.com.

Areas of application: the helmet must always be fitted with an auto-darkening filter, inner and outer cover plates. Use only for electric arc welding (MIG/MAG, MMA, TIG) and plasma welding in the temperature range −5°C to +55°C (23°F to 131°F).

Remove the protective film from both sides of new cover plates. Check that all parts are securely fitted.

11. Put on the helmet and turn the rear knob until the headgear fits firmly and comfortably.

22. Adjust the two top straps to suit your head. The flexible neck pad supports a comfortable fit.

33. Press the buttons on both sides and move the headgear forward or backward. Five positions let you adjust the distance to the filter.

44. Adjust the upward/downward angle for a clear field of view. To remove the headgear, press the buttons and slide it out of the holders on both sides.

The ADF battery life is more than 10 years under normal use. Storing the helmet in a light environment or in GRIND mode can extend battery life. Select GRIND for long-term storage.

Sensitivity: turn the “Sensitivity” knob clockwise to increase sensitivity and counterclockwise to reduce it. Use maximum sensitivity unless the application requires a different setting.

Shade: turn the “Shade” knob clockwise to increase the shade number and counterclockwise to decrease it. The available dark-state range is 8–12.

The recommended period of use is 5 years, depending on use, cleaning, storage and maintenance. Inspect regularly, replace damaged or defective parts and keep the helmet free from dust and other particles. Handle carefully and keep in a clean environment.

Helmet shell: clean with a damp cloth and water. A damaged shell can be replaced separately.

Outer and inner cover plates: clean with a damp cloth. Replace scratched, damaged or deteriorated plates; transparency can decrease over time.

ADF: no special maintenance is needed over its lifespan. If cleaning is necessary, wipe gently with a clean, soft cloth. Do not use cleaning agents, solvents or other chemicals. Cleaning damage to the filter is not covered by the warranty.

Sweatband: sweatbands from 2026 onwards are washable. Neck pad: do not wash it; replace it periodically for hygiene.

Check that the helmet and its components have not been damaged in transit. Store and transport in the original bag or packaging, in a dry place between −10°C and +40°C, below 90% relative humidity, away from direct sunlight and heat sources.

Use original AKETEK® parts. Contact a distributor or Aketek support for replacements.

If the impact-resistance symbols on the lens/filter and helmet differ, the lower level applies to the complete protector.
