Safety instructions
Please read the user instructions before using the helmet. Check that the front cover lens, the head band,
the side covers and the shade cartridge have been correctly fitted. The welding helmet must not be used
if faults cannot be remedied.
Warnings & safety restrictions
Heat and radiation that can cause eye and skin injuries are emitted during the welding process. This product
provides eye and face protection. Your eyes are always protected from ultraviolet and infrared radiation
when your are wearing the helmet, irrespective of the shade level. Appropriate additional safety clothing
must be worn to protect the rest of the body. Some people may suffer allergic reactions to particles and
substances that are released during the welding process. Materials that come into contact with skin may
cause allergic reactions to susceptible persons.
The welding helmet may only be used for welding, and for no other purpose. Optrel will not accept any
liability if the welding helmet is used for any other purpose or the user instructions are disregarded. The
helmet is suitable for all of established welding procedures except for gas and laser welding. Please pay
attention to the shade level recommendation in accordance with EN169 on the envelope. The welding
helmet may not be used for overhead welding, since there is a risk of injury from falling molten metal.
Version with replaceable side covers:
Welding with missing or damaged side covers is prohibited!
Missing side covers reduce the amount of protection from flying particles, UV- and IR-radiation etc.!
