1. The filter does not switch into dark position after an arc striking or flickers during welding. What shall I do?
- Increase the sensitivity level (optional with all models except F10, F11, M10 in M11 - see the manual). When TIG and low amperage welding applications are being used, get closer to the arc (30cm) which will significantly improve the light signal.
- Make sure that the protective plates are clean and undamaged; if not, they might be the reason of reduced light signal.
- Make sure the photo-sensors as well as the solar cells are clean and unobstructed. Do not use the filter with the broken solar cell.
- Make sure that nothing is obstructing the welding light. The torch, glove, cloth or other objects can shadow the filter and its sensors and therefore cause
improper detection of welding. The path from welding arc to the filter must always be free.
- Direct the filter toward intense light source and make a fast swing by hand in
front of the filter. The filter should switch into dark state and immediately return to transparent stage. Do not use the filter if it does not respond to this simple test.

2. The filter does not switch from dark to transparent state after the arc has gone. What shall I do?
- Make sure that there is no intensive light source like another welder's arc, working place illumination or sunlight directed to the filter sensors.
3. The view through the filter is not clear or is hazy. What shall I do?
- Clean the inside and outside protective plates with a soft cloth, if necessary slightly wetted by alcohol. Replace the protective plates if they are damaged, covered by spatters or unremovable dirt.
- Clean the filter from both sides with plain alcohol using a soft cotton cloth.
- Make sure that both protective foils from inner and outer protective polycarbonate plates are being removed.
4. The filter has a crack in the viewing area. Can I still use it?
- The optical part of the filter is damaged. Do not work with such product since the specified shadow level is not guaranteed for the entire viewing area.
5. The spatters are damaging the filter. How can I avoid it?
- To protect the filter, always use both - inner and outer protective plates. The spatters coming directly to the glass surface will permanently and irreversibly damage your filter.
- Old protective plates are less flexible and more fragile, therefore the spatters can pass through them and damage the filter.
6. The filter appears darker horizontaly along the centre of the viewing area and brighter at lower and upper parts.
- The reason for difference in darkness is an angular dependence phenomenon, which exsists on all automatic welding filters based on liquid crystal technologies. The effect is more evident when looking through the filter at an angle, which is not perpendicular to the surface of the filter. Therefore make sure that the position of the helmet provides as perpendicular view through the filter as possible. In case that angular dependence phenomenon is too bothering, it is strongly recommended to purchase the autodarkening filter incorporating the patented ADC (Angular Dependence Compensation) feature, which considerably eliminates the unwanted angular dependence of the liquid crystal cells or autodarkening filter incorporating the new patented ADC Plus (Angular Dependence Compensation) technology, which considerably improves the angular dependence of the liquid crystal cells.
