OPERATION:
HEADGEAR ADJUSTMENT

 1.  Adjust the headgear diameter with the twist knob on the back. Twist clockwise to tighten and counter-clockwise

 

to loosen.

 2.  Adjust the height by snapping the pin into the hole to lock securely in place.
 3.  To adjust the viewing angle, loosen the angle adjusting knobs on both sides of the helmet and change angle locker to 

the desired tilt position. Once achieving the desired angle, tighten the knobs until snug. The helmet should still swing 

up, but it should not drift downward when in place for welding.

 4.  To adjust the distance between the users face and ADF, loosen the distance adjusting knob on one side of the 

helmet until the headband can move back and forth freely. Reposition the headband to one of the 3 slots, as desired. 

Tighten the knob and repeat for the knob on the opposite side of the helmet. For proper auto-darkening filter 

operation, both knobs should be positioned in the same slot. (If side one is in the middle slot, side two should be in 

the middle slot.)

MAINTENANCE:
FRONT COVER LENS REPLACEMENT

Replace the front cover lens if it is damaged (cracked, scratched, pitted, or dirty). Remove the old front lens cover by 

removing the two plugs and sockets on the sides of the helmet then lifting the old front cover lens out. To install the new 

front cover lens, place lens in the opening then secure the lens using the plugs and sockets.

INSIDE COVER LENS REPLACEMENT

Replace the inside cover lens if it is damaged (cracked, scratched, pitted, or dirty). Place your finger or thumb into the 

recess and flex the inside cover lens upward until it release from one edge. Then remove any protective film or debris 

before installing the new one.

BATTERY REPLACEMENT

When low voltage indicator (inside the helmet, on the left) turns red, the battery must be changed. Remove the ADF 

assembly from the helmet, then detach the ADF from the press card. Slide open the battery compartment and replace old 

battery with a new CR2450. Close the battery compartment, reattach the ADF to the press card, and reinstall into

the helmet.

CLEANING AND STORING

Keep the sensors, solar cell, and filter lens clean. Clean filter cartridge and helmet shell using a soapy water solution and 

soft cloth. Do not use solvents or abrasive cleaning detergent. Switch the product to grind mode and put it in a clean, dry 

location for storage.

SENSITIVITY CONTROL

Five settings are available from low to high (1,2,3,4,5) by pressing “SENS” button. Sensitivity should be adjusted 

according to welding type and ambient light.
1. Setting “1” is suitable for welding with a heavy current, in bright light, or in a surrounding where light   

  

  is interfered. 

2. Setting “5” is suitable for welding with a low current or in a darker place, especially to low current argon

  arc welding.

DELAY TIME CONTROL

Five settings are available from slow to fast (0.2-1.0s) by pressing “DELAY” button. Delay time refers to the time it 

takes the filter to change from dark to light state. Delay time should be adjusted according to welding current and level 

of light. 
1. Setting “1”, delay time will be set at 0.20s, which is suitable for spot welding or short welding. 

2. Setting “5”, delay time will be set at 1.0s, which is suitable for heavy current welding or when light

  is produced.

MODE CONTROL

Three modes are available by pressing the “MODE” button for grinding, welding, or cutting.  

1. Selecting mode “GRIND”, the ADF will be suitable for grinding use.  

2. Selecting mode “WELD”, the ADF will be suitable for welding use, with a DIN level of 9-13.

3. Selecting mode “CUT”, the ADF will be suitable for cutting use, with a DIN level of 5-8.

SHADE CONTROL

Select the shade DIN 9 to 13 based upon the welding process you will use by consulting the “Shade Guide Table”.The 

variable shade control knob is for external adjustment. The welding helmet can also be used to protect the face when 

cutting, using shade DIN 5 to 8. Grind mode DIN 4 prevents filter lens from auto-darkening for grinding use.
