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
automatically changes from dark back to
light but with a pre-set delay to compensate.
The delay time can be set from SLOW(0.2s)
to MIDDLE(0.5s) to FAST(0.8s), by the DELAY
switch. The minimum delay suits spot or short
welds. The maximum delay suits heavy current
welding and reduces eye fatigue from the arc.
Selections between SLOW - 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 have
to change batteries. Rotate cover plates on the
ADF, and replace the old batteries by 2 CR2032
lithium battery. After that, put on cover plates
of battery and rotate to lock.
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
use solvents or abrasive cleaning detergent.
Switch the product to 'Grind Mode' and put it in
a clean, dry location for storage.

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
