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.
