1) Introduction
Auto-darkening welding helmets are designed to protect the eyes and face from sparks, splatter, and harmful
radiation under normal welding conditions. The auto-darkening lter (ADF) automatically changes from a
light to dark state when an arc is struck and returns to the light state when the welding arc disappears.
The Auto-darkening welding helmet comes ready to 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.
WARNING PLEASE READ THIS MANUAL CAREFULLY BEFORE USING
2) Technical Specications
Great for MMA, MIG, MAG and TIG.

3) Operating Instructions
3.1 Before Welding
5.1.1 Ensure that the internal and external protective lms are removed from the lenses.
5.1.2 Check that the batteries have sucient power to operate the helmet. The lter cartridge can last for
5,000 working hours powered by the lithium batteries and solar cells.

5.1.3 Check that the arc sensors are clean and not blocked by dust or debris.
5.1.4 Check for headband tightness before each use.
5.1.5 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.
5.1.6 Select the shade number you require at the turn of a shade knob . Finally, be sure that the shade
number is the correct setting for your application.

3.2 Sensitity
The sensitity control is set according to the welding process and ambient light.
3.2.1 Low Setting- suitable for high amperage welding and welding in areas with high levels of natural
sunlight.
3.2.2 Medium Setting - suitable for most indoors and outdoors welding.
3.2.3 High Setting- suitable for low amperage welding and welding in areas with low light conditions,
especially for low amperage argon-arc welding.
3.3 Grinding Mode
The welding helmet can also be used to protect the face during grinding.Switching to Grind mode will
prevent the lter cartridge from darkening when bright sparks are created.
3.4 Delay Time
Delay time refers to the time the cartridge lter is set to change from the dark to bright state aer welding
stops. The delay can be adjusted up to a one second delay.
3.4.1 The minimum delay is set between 0.1 to 0.2 seconds, suitable for spot or short welds.
3.4.2 The maximum delay time is set between 0.85 to 1.0 second, suitable for heavy current welding or
when sible light is produced.
3.4.3 Selections between minimum and maximum are suitable to most indoor and outdoor welding
operations.
6.1.3 Check that the arc sensors are clean and not blocked by dust or debris.
6.11.4 Check for headband tightness before each use.
6.1.5 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.
6.1.6 Select the shade number you require at the turn of a shade knob . Finally, be
sure that the shade number is the correct setting for your application.

5. Adjust the headband
5.1 Adjusts headband for proper depth on the head to ensure correct balance and
stability. (See No.1).
5.2 Adjusts the distance between the face and the lens.To adjust, adjust the
positioning screw moved to another location slot, forward or backward. Screw
down the screws.(Both sides must be equally positioned for proper vision,See
No.2)
5.3 Turn the adjusting knob located on the back of the headband left or right to
desired tightness.(See No.3)
5.4 Shift the segmental plate with different positioning hole to adjust the window
angle for clear view. (See No.4) Numbers on the adjustment slides indicate set
position so both sides can be adjusted equally.

3.3 Replacing The Battery
When the battery power is low, the lter cartridge lens may not work correctly. Replace the Batteries. To
replace the battery, rst unscrew the front lens retaining frame and remove this. Locate the battery holder
at the top of the Auto Darkening Filter and slide upwards to open. Remove the old battery and replace with
a new CR2032 battery. Close the battery holder and screw the front lens retaining frame back into position.
