WARNING :Read and understand all instruction
before using !
This Auto-Darkening lter Welding Helmet is
designed to protect the eyes and face from sparks,
spatter, and harmful radiation under normal welding
conditions. Auto-darkening lter automatically
changes from a light state to a dark state when an
arc is struck, and it returns to the light state when
welding stops.
Auto-Darkening lter Welding Helmet comes ready
for use. The only thing you need to do before your
welding is to adjust the position of the headband
and select the correct shade number for your
application.
Check the front cover lens to make sure that they are
clean, and that no dirt is covering the four sensors on
the front of lter cartridge. Also check the front/inside
cover lens and the front lens retaining frame to make
sure that they are secure.
· Inspect all operating parts before use for signs of
wear or damage. Any scratched, cracked, or pitted
parts should be replaced immediately before using
again to avoid severe personal injury.
· Check for light tightness before each use.
· Select the shade number you require at the turn of
a shade knob ( Seeing the Shade Guide Table No.1 ).
Finally, be sure that the shade number is the correct
setting for your application.
· Adjust headband so that the helmet is seated as low
as possible on the head and close to your face.
Adjust helmet's angle when in the lowered position
by turning the adjustable limitation washer.
The shade number can be set manually between 9(8)
-13 (12). Check the Shade Guide Table to determine
the proper shade number for your application. Select
a shade number by turning the shade knob until the
arrow points to the required setting (See Shade Guide
Table No.1).
· This model is designed & equipped with a special
turnover (up & down) headband mechanism. When
welder turns over the helmet to welder’s head top,
the headband mechanism makes helmet’s gravity
center to be more lower, and be coincided with the
center of welder’s head. The design of welding helmet
greatly lowers the fatigue of welder’s head ( & neck )
and make welder feel more comfortable than before
while at working.
· At the moment of starting welding, it automatically
changes lter screen from clear to dark in only 1/30,000
sec.
· Dark to clear delay adjustment : Operator can vary the
time for the lter to return to clear state.
· Outside sensitivity adjustable can make the operators
more convenient while operating.
· At the moment of stopping welding, the lter screen
automatically changes from dark to light state according
to your per-set delay time.( Turning the time-setting
switch to the "short"position--then, it can vary at
0.25s ~ 0.35s; Turning the time-setting switch .to the
"long" position -- then, it can vary at 0.5s ~ 0.8s ).
· “WELDING”/ “GRINDING” can be selective.
· The helmet utilizes high performance solar cells as
power supply and has 2 built-in 3V lithium batteries
as power back-up. No change of battery is required.
And the battery life is raised to a new limit. Under
normal welding conditions, users can expect a battery
has a lifetime of more than 6 years.
· Variable shade (DIN) from DIN9 (8) to DIN13(12) is
adjusted at the turn of a shade knob (shade variable).
· The product is in full conformity with related DIN, ISO,
EN safety standards andANSI Z87.1-2003
standards.

WARNING:
COMMON PROBLEMS AND REMEDY
The ultra high performance of UV/IR Auto-Darkening
lters provide full protection for the user's eye &
face a against UV/IR radiation during the entire
welding process, even in the light state. The UV/IR
protection level is up to Shade16(DIN) at all times.
It makes welders feel comfortable in welding
working.
· This Auto-Darkening lter Welding Helmet is not
suitable for laser welding,& Oxyacetylene Welding.
· Never place this Helmet and Auto-darkening lter
on a hot surface.
· Never open or tamper with the Auto-Darkening
Filter.
· Before operating, please make sure if the
function-setting switch set the suitable location
“WELDING”/“GRINDING”, or not. This Auto-darkening
lter welding helmet will not protect against severe
impact hazards,
· This helmet will not protect against explosive
devices or corrosive liquids.
· Don't make any modications to either the lter or
helmet, unless specied in this manual. Don't use
replacement parts other than those specied in this
manual. Unauthorized modications and replacement
parts will void the warranty and expose the operator
to the risk of personal injury.
· Should this helmet not darken upon striking an arc,
stop welding immediately and contact your supervisor
or your dealer.
· Don't immerse the lter in water.
· Don't use any solvents on lters' screen or helmet
components.
· Use only at temperatures : - 5°C ~ + 55°C ( 23°F ~
131°F ).
· Storing temperature : - 20°C ~ + 70°C (-4 ° F ~ 158° F).
· Protect lter from contacting with liquid and dirt.
· Clean lters' surfaces regularly; do not use strong
cleaning solutions. Always keep sensors and solar cells
clean using a clean lint-free tissue/cloth.
· Regularly replace the cracked/scratched/pitted front
cover lens.
Severe personal injury could occur if the user fails to
follow the aforementioned warnings, and / or fails to
follow the operatinginstructions.
* Irregular Darkening Dimming
· Headband has been set unevenly and there is an
uneven distance from the eyes to the lter's lens
(Reset headband to reduce the dierence to lter).
** Auto-Darkening Filter Does Not Darken Or Flickers
· Front cover lens is soiled or damaged (change lens cover)
· Sensors are soiled (clean the sensors’surface)
· Welding current is too low (turns the switch to the
"Long" position).
*** Slow response
· Operating temperature is too low (do not use at
temperatures below - 5 ° C or 23 °F).
**** Poor Vision
· Front /inside cover lens and/or lter lens are soiled
(change lens)
· There is insucient ambient light
· Shade number is incorrectly set (reset the shade number)
***** Welding Helmet Slips
· Headband is not adjusted properly (readjust headband)
WARNING ! Operator must stop using the auto - darkening
lter welding helmet immediately if the abovementioned
