AUTODARKENING WELDING PROTECTION
FILTER
OPERATION
JACKSON SAFETY
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 pas-
sive 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
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 con-
junction 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
JACKSON SAFETY
filters are suitable for all types of electro-
®
welding: covered electrodes, MIG/MAG, TIG/WIG, plasma
welding, cutting and laser welding (only selected models with
two shade ranges, i.e.6-8 and 9-13), except for gas welding.

FUNCTIONS
JACSKON SAFETY
filters are supplied ready
®
for use. Check the degree of required protec-
tion for specific welding procedure and if a
certain model allows you, select the recom-
mended shade, light sensitivity as well as
opening time delay.
Shade adjustment: Some models (Grand DS, Grand ES)
enable shade adjustment range from 9 to 13. Grand GDS has
two shade ranges, i.e. 6-8 and 9-13. It can be adjusted by the
knob »Range« which is located on the filter. The external knob
for shade adjustment has two shade ranges (6-8 and 9-13)
marked in two different typefaces (positive and negative). The
adjustment of the knob »Range« defines the range which is
being used.
Adjustment of sensitivity: Most welding applications
can be performed with welding light sensitivity set to maximum.
The maximum sensitivity level is appropriate for low welding
current work, TIG, or special applications. The welding light
sensitivity has to be reduced only in some specific surrounding
lighting conditions in order to avoid unwanted triggering. As a
simple rule for optimum performance, it is recommended to set
sensitivity to the maximum at the beginning and then gradually
reduce it, until the filter reacts only to the welding light flashes
and without annoying spurious triggering due to ambient light
conditions (direct sun, intensive artificial light, neighboring
welder's arcs etc.).
Opening time delay adjustment: The opening time
delay can be adjusted from 0.1 to 1.0 seconds. It is recom-
mended to use a shorter delay with spot welding applications
and a longer delay with applications using higher currents and
longer welding intervals. Long er delay can also be used for
low current TIG welding in order to prevent the filter opening
when the light path to the sensors is temporarily obstructed by
a hand, torch, etc.
Function welding/grinding (model Grand GDS only):
For these filters, two modes of operation can be selected:
welding or grinding. By selecting the position »Grind«, the
filter switches off and it will not be triggered by the sparks
generated during grinding. Before restarting welding work,
the knob should be set back to the »Weld« position.
