Glossary
Filter viewing area (WxH)
The size of the transparent part of the light filter — the "working window", the area through which the welder sees the place of work. A larger working window provides ease of use and a wide field of view, but it significantly affects the cost of the mask and somewhat reduces the strength of the light filter.
Filter cartridge dimensions (WxH)
The overall dimensions of the light filter for which the mask is designed, taking into account the working window, protrusions for mounting, batteries, sensors and other structural elements. This indicator is especially important for models that are not equipped with light filters: without knowing the size, it is very difficult to choose the right cartridge. In other cases, data on the size of the cartridge is needed mainly when looking for a replacement for a failed colour filter.
Operating temperature
The range of ambient air temperatures at which the mask is guaranteed to be able to function normally. This parameter is especially important for "chameleons" (see "Functions"), because. the performance of the automatic filter directly depends on external conditions (in particular, at low temperatures, the response time may increase).
