If the filter switches to dark and then turns to light again while there is still an arc, the sensitivity
level may not be properly selected or there is some obstruction of light from the arc to the sensors.
1. Increase the sensitivity level.
2. Move the filter closer to the arc (1-2 feet from the arc is optimum)- but not close.
3. Make sure that the filter is pointed directly at the arc, and that the sensors are not blocked from
direct exposure to the arc (including not blocked by your arm, welding torch gun or nozzle).
4. Make sure that the cover lens is clean.
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 slighter 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-dar-
kening filter is designed to be perpendicular to the surface of the filter lens. No corrective action is
needed.
Sports in the filter lens. The shape and/or sports 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.
Push the On/Off button and the shapes/spots will disappear.
Partial light/ shading.
There appears to be a distinct shade difference in portion of the filter lens and there is not 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 hel-
met 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 an
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. The batteries shall be
CR2450 lithium batteries.
