Symptom 

Possible Causes 

Solution 

Lighter shaded areas 

at the edge and corner 

of the filter lens 

The auto-darkening filter uses 

liquid crystal which exhibits an 

angle of view effect. In the dark 

state, it is normal for welder to 

notice slightly lighter shaded areas 

at the edge and corners of the filter 

lens. This does not represent any 

health or safety hazard. The 

optimum viewing angle of the auto-

darkening filter is designed to be 

perpendicular to the surface of the 

filter lens. 

No corrective action is needed 

Spots in the filter 

lens. The shape and/or 

spots  may  appear  to 

"grow" in the lens 

It occurs after the lens has been 

shut off. The liquid crystal within 

the filter unit loses its electrical 

polarity after the electrical current 

is cut off. The liquid crystal, 

therefore, "relaxes" and causes the 

shape/spot to appear. It is a 

normal condition, and has no 

impact on the operation of the lens 

No corrective action is 

needed. 

Partial light/shading 

There appears to be a distinct 

shade difference in portion of the 

filter lens and there is no crack in 

the unit.  It may be caused by the 

leakage of light in the filter unit or 

reflection of light from light clothing 

into the helmet or the angle of 

looking through the lens, or optical 

illusion caused by "visible light" 

when wearing bifocals. 

1. Make sure the filter unit is 

properly installed; 2. Wear 

dark clothing; 3. Make sure 

the welding helmet is adjusted 

properly so that the welder is 

looking straight and directly 

through the lens; 4. Welder 

who wears bifocals may notice 

a lighter shade in the bottom 

of the filter lens. This is normal 

and is  optical illusion caused 

by "visible light." No correction 

is needed for this symptom. 

Sections of the filter 

not going dark, 

distinctive lines 

between light and dark 

areas 

The ADF filter may be cracked. 

The crack can be caused by 

dropping or hitting the helmet or by 

welding spatter on the filter. 

Stop welding immediately and 

replace the filter if cracked. 

Short Battery Life 

If the batteries last only a few days 

even when usage is not intense, 

either the battery is wrong type or 

the battery contact is not good. 

Check the battery and battery 

contact, make sure battery 

type is CR2032
