SENSITIVITY CONTROL
The sensitivity can be set to LOW or HIGH by
using the infinitely dial knob. The LOW setting
suits excess ambient light or with another weld-
ing machine close by. The HIGH setting suits low
amperage welding and welding in areas with
low light conditions, especially low amperage
argon arc welding. Selections between LOW
and HIGH are suitable for most of indoor and
outdoor welding operations.
DELAY CONTROL
When welding ceases, the viewing window au-
tomatically changes from dark back to light but
with a pre-set delay to compensate. The delay
time can be set to MIN (0.1 sec) or MAX (1.0 sec),
by infinitely dial knob inside the cartridge. The
minimum delay suits spot or short welds. The
maximum delay suits heavy current welding
and reduces eye fatigue from the arc. Selections
between MIN and MAX are suitable for most of
indoor and outdoor welding operations.

MAINTENANCE

FRONT COVER LENS REPLACEMENT
Replace the front cover lens if it is damaged
(cracked, scratched, pitted or dirty). Remove
the old front cover lens by pressing two Lock
Switches at the bottom of the Retaining Frame
and pull the frame and ADF out. Take the old
front cover lens out, and remove any protective
film before installing the new one.
INSIDE COVER LENS REPLACEMENT
Replace the inside cover lens if it is damaged
(cracked, scratched, pitted or dirty). Place your
finger or thumb into the recess and flex the
inside cover lens upwards until it releases from
one edge. Then remove any protective film be-
fore installing the new one.
BATTERY REPLACEMENT
When low voltage indicator turns red, you must
change batteries. Replace batteries by remov-
ing ADF from the retaining frame. Slide cover
plates on the top left and right, and replace the
old batteries by CR2450 lithium batteries. After
that, put on cover plates of batteries and install
ADF back to frame.
CLEANING AND STORING
Keep the sensors, solar cell and filter lens clean.
Clean filter cartridge and helmet shell by using
a soapy water solution and soft cloth. Do not
6
use solvents or abrasive cleaning detergent.
Switch the product to 'Grind Mode' and put it in
a clean, dry location for storage.

FILTER DOES NOT DARKEN WHEN ARC IS
STRUCK
Grind mode selected. Select Weld Mode and ad-
just Shade from 9 to 13
Sensors or Solar Panel blocked. Make sure sen-
sors or solar panel are exposed to weld arc with-
out blocking.
Set Sensitivity to LOW. Adjust sensitivity to re-
quired level.
Low Voltage of lithium battery. Replace with
new lithium battery if indicator turns red.
FILTER DARKENS WITHOUT ARC
Set Sensitivity to HIGH. Adjust sensitivity to re-
quired level.
FILTER REMAINS DARK AFTER WELDING
Set Delay to MAX. Adjust delay to required
level.
