The filter does not darken after striking an arc. Whats wrong?
Your batteries may be dead or installed incorrectly. Check installation and/or insert new batteries and try the unit again. If the filter still does not darken, inspect the cover plate and filter to make sure the sensors are unobstructed, clean, and unbroken. Inspect your surroundings to make sure the sensors are not shadowed or covered when in the position you will be in while welding. If your filter still does not darken, contact our technical support desk at 1-800-323-1742 for additional assistance.
