Safety instructions

Before using the helmet, please read the user instructions. Check that the front
cover lens has been correctly fi tted. You must not continue welding if the welding
fi lter is non-functional.
Precautionary measures & safety restrictions
Heat and radiation released during arc-welding can cause eye injuries and skin
burns. This product provides protection for the eyes and face. Your eyes are always
protected against ultraviolet and infrared radiation when you wear this helmet
regardless of the shade level. Wear appropriate protective clothing in order to
protect the rest of your body.
The welding helmet is only suitable for welding and grinding and not for any other
application. SPERIAN Welding Protection AG assumes no liability when the
helmet is used for other than the intended purpose or when the user instructions
are disregarded.
The helmet is suitable for all established welding procedures, with the exception
of laser welding.
Standby mode
The welding fi lter has an automatic switch-off function, which increases the service
life of the product. If no light falls upon the solar cells for a period of approx. 15 min.,
the welding fi lter automatically switches itself off. To reactivate the fi lter, the solar
cells must be briefl y exposed to daylight.
If the welding fi lter no longer activates or darkens when the welding arc ignites, it
must be regarded as non-functional and replaced.
Warranty & liability
Please take the warranty conditions from the directives of the national SPERIAN
Welding Protection AG sales organisation. Please contact your SPERIAN Welding
Protection AG dealer for further information in this connection.
Warranties are granted for material and manufacturing defects only. In the case
of damage caused by improper use, unauthorised interventions or the use of the
helmet for a purpose other than that intended by the manufacturer, the warranty and
liability are no longer valid. Likewise, liability and the warranty are no longer valid if
spare parts other than those sold by SPERIAN Protection are used.
Use
1. Head band. Adjust upper band (1) to your head size. Depress ratchet knob (2)
and turn until the head band sits fi rmly yet comfortably.
2. Eye distance and inclination. The distance between the welding fi lter and
the eyes can be optimally adjusted by loosening the locking knobs (3). The
setting should be identical on both sides to exclude tilting. After this adjustment,
retighten the locking knobs.
The helmet inclination can be adjusted via knob (4).
3. Shade level. By turning knob (5), you can select a shade level between DIN 9
and DIN 13.
Cleaning
The welding fi lter and the front cover lens must be cleaned with a soft cloth at regular
intervals. Do not use strong cleaning agents, solvents or alcohol.
Storage
The welding helmet must be stored at room temperature and low humidity.
