► PROTECTION SCREEN REPLACEMENT
1. Remove the external frame. From the internal side of the helmet shell squeeze the two
pins towards each other, release the frame and slightly push it out (1.a), then rotate it
to release the bottom two pins (1.b).
2. Hold the protection screen with your thumb and middle finger on the side extensions
along the indents in the helmet shell intended for your fingers. Press on the protection
screen to slightly bend it and remove it from the holder slots (2.).
3. Insert a new protection screen and close the cover as described in the previous section,
under points 3 and 4.

During assembly of the helmet and welding filter, or during the replacement of
the protection screens, make sure that all parts are firmly in place thus prevent-
ing any light from entering the helmet. Should there still be any light entering,
repeat the procedure until the problem is eliminated, otherwise the helmet must
not be used for welding. Before placing the new protection screens, always re-
move the protection layers from both sides.
► AUTODARKENING WELDING PROTECTION FILTER
► OPERATION
KEMPER autodarkening welding protection filters operate on the basis of 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.
KEMPER autodarkening welding protection filters are manufactured 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. Replace potentional malfunctioned (check that the autodarkening filter
turns dark if you strike the welding arc) or physically damaged autodarkening welding filter.
Protection screens, both internal and external (polycarbonate or CR39), must be
used in conjunction with the autodarkening filter in order to protect it against
permanent damage.
► USAGE
An autodarkening 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. In case that you have only bought a
filter without the helmet, you need to select the appropriate helmet designed to be used
in combination with an autodarkening welding protection filter. It has to allow the filter,
including the internal and external protection screens, to be adequately mounted into
the helmet. There should be no increased point tensions caused by the fixing frame or
mounting system, as they could cause severe damage to the filter. Make sure that 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.

MIG/MAG, TIG/WIG, plasma welding, cutting, except for gas welding.
► FUNCTIONS
KEMPER filters are supplied ready for use. Check the degree of required protection
for specific welding procedure and if a certain model allows you, select the
recommended shade, light sensitivity as well as opening time delay.
