Auto-Darkening Welding Helmet
WARNING
Read and Understand All Instructions Before Using!
This 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 a
light state to a dark state when an arc is struck, and returns to the light state when welding stops.
The auto-darkening welding helmet comes ready for use. The only thing you need to do before welding
is to adjust the position of the headband and select the correct shade number for your application.
BEFORE WELDING
1.Check the front cover lens to make sure it is clean, and that no dirt is covering the four sensors on
the front of filter cartridge. Also, check the front/inside cover lens and the front lens retaining frame
to make sure that they are secure.
2.Inspect all operating parts before use for signs of wear or damage. Any scratched, cracked, or
pitted parts should be replaced before using again to avoid severe personal injury.
3.Check for light tightness before each use.
4.Select the shade number required by turning the shade knob (see the Shade Guide Table No. 1).
Finally, be sure that the shade number is the correct setting for your application.
5.Adjust headband so the helmet is seated as low as possible on your head and close to your face.
Adjust helmet’s angle when in the lowered position by turning the adjustable limitation washer.
DARK SHADE NUMBER SELECTION
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 the Shade Guide Table No. 1).

4. Variable Shade Control I Delay time
Sensitivity Control I Grinding Control
1) Welding/Grinding Handle: when grinding, the helmet shell cannot bear the welding spatter
which is more than 43grams and exceeding 120m/sec. The helmet meets standard DIN EN
175:1997 (B impact Level). For other body parts helmet cannot protect, please wear other safety
products for protection.
2)Sensitivity Knob: Before welding, please adjust the sensitivity to high position, if encountering the
interference of Lighting lamp(the filter is darkening while not welding),please adjust the sensitivity
towards low position slightly until the filter returns to light state (please don't make the helmet
towards to light lamp source during this process, should towards to welding work piece). During
welding, the sensitivity knob should be adjusted as high as possible, or it will affect the darkening
speed of filter.
Attention: Operator must stop using the helmet immediately and contact with the dealer in time if
the filter cannot be darkening or the darkening speed is slow or the filter is flash.
3) Shade Knob-before welding, please adjust the Shade Knob to proper shade no. based on welding process and welding amperage. to make primary welding for test ( Seeing the Shade Guide
Table No. 1 ). If the shade of filter is too darkening or too light, please adjust the Shade Knob
slightly to correct position till the eyes can see the welding spot which is not glaring and can see

welding molten pool. Please kindly note that it will damage the eyes if using welding helmet under
incorrect shade no.(too darkening or too light) for a long time.
Attention: If the filter cannot be darkening or the darkening shade is not enough or the darkening
speed is slow or the filter is flash, for such abnormal work, please find the reason immediately. If
operator cannot solve the problem, please must stop using the helmet immediately and contact
with the dealer in time.
4) Delay time Handle --There are three position (Long, Middle, Short), it can adjust the switching
time of filter from dark state to light state, avoid the da-mage to eyes from the residual arc of
welding molten pool due to too fast switching time to light state when welding is end (Break arc).
The delay time is 0.3s-0.5s (at short position); 0.4s-0.6s (at middle position); 0.6s-0.9s (at long
position). The switching time may vary due to different welding types and different sensitivity setting even delay time handle is at the same position. If the filter is flash under low current welding,
please adjust the delay time handle to long position, this can help to solve this problem.
1 ) Test button
2 ) Battery Indicator
5. Test
1 ) Test button --It can test if the lithium battery is
with power and if the filter is under normal work. lf
the battery indicator is lightening (red) and the filter
can be darkening when pressing down test button, it
means the filter is under normal work.
If the battery indicator is lightening but the filter is not
darkening, it means there is some problem with the
filter; please don't use this filter anymore.

USER’S MANUAL
• This model is designed & equipped with
a special turnover (up & down) headband
mechanism. When welder turns over the helmet
to welders 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 working.
• Headband has been set unevenly and there is an uneven distance from the eyes to the filter's
lens (Reset headband to reduce the difference to filter).
