/ to be used with AIRMAX
Face seal replacement:
1. Unfasten the 7 screws on the outside using a positive drive screwdriver using your
fingers to secure the hex nut on the inside of the helmet.
2. Lifting from the chin remove the faceseal pulling clear of the headgear airduct.
3. Insert the positive drive screws and hand tighten start from the working towards the
top of the helmet.
4. Insert the face ensureing the D ring is facing outside the helmet and pointing in the
direction of the chin.
5. Tighten each screw a little further using a positive drive screwdriver using your
finger to hold the hex nut (ensuring not to over tighten hand tight only).
AUTODARKENING 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
ing to EN 379 requirements and are CE 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 mount-
ing 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.
FIELD OF APPLICATION
The Duo filter is suitable for most types of electro-welding: e.g. covered electrodes and
MIG/MAG. It may be used for some TIG applications above 20 amps. The Duo filter is not
suitable for laser welding.
