INSTRUCTIONS FOR USE
Caution!
1 The auto-darkening welding helmet is suitable for neither laser welding nor oxygen acetylene welding.
2 The clear, protective plate should always be installed to protect the fi lter from damage.
3 Do not make changes or replacements to the welding helmet.
4 Stop using immediately if the fi lter cannot change to dark, and contact the dealer.
5 Do not use alcohol, petrol or thinners to clean the fi lter; do not immerse it in water.
6 Operating temperature: -5 °C ÷ + 55 °C (23 °F ÷ 131 °F); the reaction of the auto-darkening welding
helmet will be slow if the ambient temperature is too low.
7 Replace the protective fi lms immediately if they are broken or scratched, since they may affect the view
and seriously reduce the protective performance.
8 Replace the protector immediately if it is broken or scratched. Do not use any hard objects in contact
with the surface of the fi lter lens.
9 Clean the fi lter surface, sensors and solar cells regularly.
10 The helmet cannot prevent serious impact, explosive or corrosive liquid damage. If it is worn on
ophthalmic glasses, it can transmit impact, thereby causing a hazard for the wearer.
11 The materials of this helmet, which may come into contact with the skin, can cause allergic reactions
in sensitive people.
Note: Failure to take the above-mentioned precautions may result in serious personal injury.
The meaning of the marking
Marking for welding helmet: BETA EN175 F (BETA = manufacturer identifi cation, EN175 = testing stan-
dard, F = low energy impact, 45m/s)
Marking for Front Cover: BETA F (BETA = manufacturer identifi cation, F = low energy impact, 45m/s)
Marking for Back cover: BETA 1 F (BETA = manufacturer identifi cation, 1 = optical class, F = low energy
impact, 45m/s)
Marking for Automatic darkening fi lter: 4/9-13 BETA 1/1/1/3/379 (4 = light state, 9-13 = dark states, BETA
= manufacturer identifi cation, 1= optical class, 1= diffusion of light class, 1= homogeneity class, 3 = angle
dependence class, 379 = testing standard)"
Note: if protection against high speed particles at extremes of temperature is required then the selected
eye-protector should be marked with the letter T immediately after the impact letter.
If the impact letter is not followed by the letter T then the eye protector shall be used against high speed
particles at room temperature.
Always wear the helmet with the internal clear fi lter.
