And The Face.
• Step1: Loosen the block nut (See "T" in Fig. 2) to adjust
the distance between the helmet and your face in the
down position.
• Step2: Loosen the block nut on either side of the
helmet and slide it nearer or further from your face.
(See adjustment "Z" in Fig. 2). It is important that your
eyes are the same distance from the lens. Otherwise
the darkening effect may appear uneven.
• Step3: Re-tighten the block nut when adjustment is
complete.

4. WELDING FILTER OPERATION/FEATURES

4.1 Selecting the Operating Mode
Use the switch button on the back of shade cartridge to
select the mode appropriate for the work activity. (see
the technical specification of your helmet).
Grind mode - can be selected by rotating the shade
control knob counter clockwise till an audible click is
heard. The variable shade control knob is mounted on the
exterior of the helmet shell.
Grind mode-used for metal grinding applications. In this
mode the shade function is turned off. The shade is fixed
at shade DIN 3.5 that allows a clear view to grind while
the helmet providing face protection.
"Grind Mode Is Intended For Grinding Only Not For
Welding."
Grind Mode - Not available in models: 2000 E 11, 2000
E.
Weld mode - Used for most welding applications. In this
mode the shade functions is turned on when it optically
senses a welding arc. Select shade level, delay time and
sensitivity as required.
4.2 Selecting Shade Level
Select the shade level you require according to the
welding process you will use by referring to the "Shade
Selection Chart" below for settings. Turn the shade
control dial on the lens to the shade number require. (see
Fig.3). Only 2000 E, 2000G.
4.3 Selecting Delay Time
When welding ceases, the viewing window automatically
changes from dark back to light but with a pre-set delay
to compensate for any bright afterglow on the workpiece.
The delay time\response can be set to "MIN" short: 0.1
sec.) or "MAX" (long:1.0sec.), as you require by using the
infinitely dial knob on the back of the shade cartridge.
(see Fig.7)
It is recommended to use a shorter delay with spot
welding applications and a longer delay with applications
using higher currents. Longer delays can also be used for
low current TIG welding in order to avoid the filter opening
when the light path to the sensors is temporarily
obstructed by a hand, torch, etc.
4.4 Sensitivity
The sensitivity can be set to "Hi"(high) or "Lo"(low) by
using the infinitely dial knob on the back of the shade
cartridge. The "Min-Max" setting is the normal setting for
everyday use. The maximum sensitivity level is
appropriate for low welding current work, TIG, or special
applications. While the operation of the helmet is
disturbed by excess ambient light, or another welding
machine close by, use the "low" setting. (see Fig.8)
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 flash and without annoying
spurious triggering due to ambient light conditions (direct
sun, intensive artificial light, neighboring welder's arcs,
etc).

5. MAINTENANCE

5.1 Replacing Front Cover Lens:
For model, see "TECHNICAL SPECIFICATIONS"
Model 1: (fig 12)
To replace the front cover lens, place your fingernail in
recess below the mask and flex lens upwards until it
releases from edges.
Model 2: (fig 13)
To replace the front cover lens remove lens cassette by
moving locks toward center (1) and lift up the lens
cassette (2) to remove/replace the front lens cover (3).
Where this is not the lever, proceed by removing the two
plastic screws. Take out the old cover lens. Place the new
cover lens into the right position. Please remove the
protection film from both sides the new cover lens if it
comes with the film on.
5.2 Replacing Inside Clear Lens:
Replace the inside cover lens if it is damaged. Place your
fingernail in recess below the cartridge of view window
and flex lens upwards until it releases from edges of the
cartridge of view window.
5.3 Change The Shade Cartridge:
Remove ADF holder assembly from helmet shell. Flex top
end of the ADF holder to allow ADF cartridge to be
removed from frame. Install new ADF cartridge into frame
(see fig.10) Make sure that the ADF cartridge is inserted
in ADF holder correctly as shown. Install ADF holder
assembly into helmet shell.
