AUTO-DARKENING WELDING PROTECTION FILTER
OPERATION
JACKSON SAFETY
a liquid crystal light shutter that protects the welder's eyes against intense visible light
emitted during the welding process. In combination with the permanent passive IR/UV
filter, it protects against hazardous infrared (IR) and ultraviolet (UV) light. The protection
against harmful radiation is present regardless of the shade level or potential malfunction
of the filter, beyond the darkest shade number marked on each specific model.
JACKSON SAFETY
according to EN 379 requirements and are CE, DIN as well as DIN Plus certified. They
are not intended to be used as a protection against impacts, flying particles, molten
metals, corrosive liquids or hazardous gases. Always replace potentially malfunctioned
(check that the auto-darkening filter turns dark if you strike the welding arc) or
physically damaged auto-darkening welding filters.
Protection lens, both internal and external (polycarbonate), must be used
in conjunction with the auto-darkening filter in order to protect it against
permanent damage.
USAGE
An auto-darkening welding protection filter built into a welding helmet is considered to
be »Personal Protection Equipment« (PPE) protecting the eyes, face, ears and neck
against direct and indirect hazardous light of the welding arc. If you have bought only
a filter without the helmet, you need to select the appropriate helmet designed to be
used in combination with an auto-darkening welding protection filter. It has to allow the
filter, including the internal and external protection lens, to be adequately mounted into
the helmet. There should be no increased tension points caused by the fixing frame or
mounting system, as they could cause severe damage to the filter. Make sure that the
solar cells and photo-sensors are not covered by any part of the helmet, as this could
prevent the proper operation of the filter. If any of these conditions occur, the filter may
not be suitable for use.
FIELD OF APPLICATION

electrodes, MIG/MAG, TIG/WIG, plasma welding and cutting. JACKSON SAFETY
