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.

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).

Grinding mode

A special mode of operation of the chameleon mask, in which the light filter sensors are completely turned off — thus, it constantly remains transparent and does not respond to any flashes. This mode is useful for jobs that can produce fairly bright flashes of light, but do not require dimming. A classic example of such work is grinding with a “grinder” or a machine tool, when sparks can fly from the workpiece; hence the name of this function — "grinding" mode.
