Auto -Darkening Filter
Welding Helmet
Auto -darkening welding helmet is designed to protect the
eyes and face from sparks, spatter, and harmful radiation
under normal welding conditions. Auto -darkening filter
automatically changes from light to dark state whenthe arc
is struck, and returns to the light state whenwelding stops.
Auto -darkening welding helmet comes ready to use. The only
thing youneed to do before welding is to adjust the position
of the headband and select the correct shade number for your
application.
There is also a visor for protection onother operations.
BEFORE WELDING
•Checkthe front cover lens to make sure that they are cleanand there is no dirt covering the
four sensors on the front of the filter cartridge and check the front/inside cover lens to make
sure that they are secure.
•Check all operatingparts 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.
•Checkfor light tightness beforeeachuse.
Select a shade number by the shade knob (see Shade Guide Table No.1) ensuring that the shade number is
the correct setting for your application. Adjust the headband so that the helmet is seated as low as possible
on the head and close to your face. The angle of the helmet is adjusted using the buckles.
DARK SHADE NUMBER SELECTION
The shades ranges from 9-13. The shade section is selected by switch K4. When used for grinding, you can
set the Grind/Weld switch (1<5) to "GRIND". Refer to the shade guide table to determine the proper shade
number for your application. Select a shade number by the shade knob (Shade guide Table No.1).The shade
goes darker from9 to 13 gradually by turningknob 1<2.
PRODUCT FEATURES
The helmet is designed & equipped with a special turn over (up Er down) headband mechanism. When the
user lifts the helmet, the headband mechanism aligns the helmet's centre of gravity to with the user's head.
This greatly reduces fatigue of the user's head (and neck) making the user more comfortable when working.
When welding, the helmet automatically changes the filter screenfromclear to dark in 1/25,000 sec. The
delay time from dark to clear is set between 0.2 sec and 1 sec, which can be adjusted by the delay knob.
The helmet utilises high performance solar cells as a power supply and 2 built-in 3V lithium batteries
(CR2032) as power back-up. The power is switched off automatically within 10-15mins of stopping work.
Under normal welding conditions, users can expect a battery lifetime of more than a year. The lithium
batteries can be replaced by ones of the same size and specification when exhausted.
The helmet is in full conformity with related DIN,ISO,EN safety standards and ANSI Z87.1-2010 standards.
The ultra -high performance of UV/IR auto -darkening filters provide full protection for the user's eyes and
face against UV/IR radiation during the entire welding process, even in the light state. The UV/IR protection
level is up to Shade 16(DIN) at all times, which increases comfort during welding work.
