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

3.2 Sensitity
The sensitity 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 aer 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.

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) Maintenance
5.1. Cleaning and disinfection: Clean lters surfaces regularly; do not use strong cleaning solutions. Always
keep sensors and solar cells clean using a clean lint-free tissue/cloth. You can use alcohol and cotton to
wipe.
5.2. Use neutral detergent to clean the welding shell and headband.
5.3. Replace outer and inner protection plates periodically.
5.4. Do not immerse the lens in water or any other liquid. Never use abrasives, solvents or oil based cleaners.
5.5. Do not remove the auto-darkening lter from the helmet. Never try to open the lter.
6) Safety Warning
• Recommended usage period of 3 years from date of rst use. The duration of the helmet depends on
various factors such as usage, cleaning, storage and maintenance. Frequent inspections and replacement
of damaged components is recommended.
• Materials that may come into contact with the wearer’s skin could cause allergic reactions to susceptible
indiduals
• Eye-protectors against high speed particles worn over standard ophthalmic spectacles may transmit
impacts, thus creating a hazard to the wearer.particles at room temperature.

• If protection against high speed particles at extremes of temperature is required, then the selected eye-
protector should be marked with the letter T immediately aer the impact letter, i.e. FT, BT or AT. If the
impact letter is not followed by the letter T then the eye protector shall only be used against high speed
1. This Auto-Darkening lter welding helmet is not suitable for laser welding and Oxyacetylene welding.
2. Never place this Helmet and Auto-Darkening lter on a hot surface.

13. Clean lters’ surfaces regularly; do not use strong cleaning solutions. Always keep sensors and solar
cells clean using a clean, lint-free tissue/cloth.
14.Regularly replace the cracked/scratched/pitted front cover lens.
7) Troubleshooting
Irregular Darkening or 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 (change the “SENSITIVITY” to “HIGH”)
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 and
contact the supplier if the above-mentioned problems cannot be corrected.
