Auto-Darkening lens Tips

If the auto darkening lens in your welding helmet:

Has become difficult to see through the filter

1.Clean or replace the cover plates when the become dirty or discolored.
2.Clean the auto-darkening filter, the location of the filter is listed in the owner’s manual.

The Auto-Darkening Filter will not darken after striking an arc

1.Test the auto-darkening filter as directed in the “Preparation for Use” section of the User Manual.
2.Make sure the outer cover plate is clean, clear and unobstructed.
3.Remove and inspect the auto-darkening filter making sure the sensors and solar panels are unobstructed, cleaned, and not broken or discarded.
4. Do not continue to use the auto-darkening lens if the problem persists.

The Auto-Darkening Filter is slow to darken

1.Solar powered auto-darkening filters are designed to operate on very low voltage. If the filter had not been used for a period of time such as a day or more, the circuitry will enter a sleep state. In the sleep state the battery can retain full voltage potential. It will awaken when you test it or begin welding. For instance if the product is a shade 10, the first time it darkens it will initially darken to perhaps shade 8 then transition to shade 10. Then after that it will darken to shade 10 each and every time. Note: As long as you are wearing your helmet with an auto-darkening filter you are protected from UV/IR (ultraviolet/infrared) rays in the dark and light state and every shade in between.
2.Colder temperatures will slow the switching speed of an auto-darkening filter. Once the heat from welding process warms up the components, switching speeds will increase. Auto-darkening filters work best at room temperatures.

The Auto-Darkening Filter goes light or flickers on/off while welding

1.Clean or replace outer polycarbonate lens if it becomes soiled or cloudy.
2.Check to make sure that the sensors and solar panels are not damaged, dirty or covered with a smoky film. Clean filter if necessary.
3.The front of the auto-darkening filter should be perpendicular to the welding arc.
4.If the Filter does not hold the dark shade contact the lens manufacture.

The Auto-Darkening Filter stays dark after you stop welding

1.Exceeding the temperature limitations may also cause the LCD to stay dark. Let the filter cool down and try not to overheat it again by viewing the arc from the side and not directly above or by increasing the distance the filter is in relationship to the arc.

2.Your filter may remain dark after welding if you are facing a bright light or the sun. If this is the case either look away or pass your hand between the source of the light and the sensors. By doing this the light source will be interrupted and the filter will clear.

The Auto-Darkening Filter has a crack running through the front of the viewing area

1.The UV/IR protection may be compromised resulting in burns caused by Ultraviolet or Infrared radiation. Cease using the product if the problem exists.

Spatter is causing damage to the filter

1.Refer to the spatter protection section of the user manual.
The Auto-Darkening Filter has sever spatter damage
1.Do not operate the product if this condition exists. The UV/IR protection may be compromised. Unfiltered welding light may penetrate through the filter and may result in severe eye damage and burns.

This is why I use an old flip face hood. No batteries, no solar panels, no forgetting to turn it on. It works every time.
