True View 3395, 2 X 4-1/4 " Drop-in Single Shade Auto Darkening Filter, Shade 11

OPERATING AND MAINTAINING YOUR NEW FILTER:
This welding filter works in virtually all applications except ocy-acetylene, laser and very low amperage welding.
This new welding filter is always ready to function.  The unique rechargable battery ensures you many years of reliable operation.
Usually daily usage will keep the battery fully charged. If you are going to store your filter for over a period of a month, it is recommended that you store the filter with solar panels facing a source of light e.g. sunlight or a lamp used daily.
In order to increase the shade level, passive shade 1 and 2 polycarbonates could be inserted behind the welding filter.  The additional shade will affect both light and dark shades.
