Glossary
Min. degree of darkening
The smallest degree of obscuration provided by the chameleon mask (see "Type") when the light filter is activated. Recall that dimming is indicated in DIN units, the larger the number in this paragraph, the darker the filter.
This parameter is indicated only for models with dimming control (see "Functions"). From the minimum degree of dimming depends on the extent to which you can adjust the light transmission. At the same time, we recall that a darker light filter protects better from bright light, but worsens visibility; so for some tasks, a relatively low level of obscuration may be optimal. Accordingly, the lower this indicator, the wider the adjustment range of the filter, the more opportunities the user has to adjust it (with the same maximum threshold). On the other hand, the expansion of the adjustment range significantly affects the cost, and such characteristics are not always required. Therefore, nowadays, you can find chameleon masks both with a small ( 5 DIN and even less), and with a fairly significant minimum dimming ( 7 DIN or even 9 DIN). And it’s worth choosing here, depending on what is more important for you: an extensive range of adjustment or low cost.

Max. degree of darkening
The greatest degree of obscuration provided by the chameleon mask (see "Type") with the filter activated. For models that do not have dimming adjustment (see "Functions"), this item indicates the standard level of light transmission of the included light filter.
Recall that dimming is indicated in DIN units, the larger the number in this designation, the darker the filter. In turn, a darker mask gives better protection from bright light, but worsens visibility; Accordingly, different degrees of dimming may be optimal for different tasks. Detailed recommendations on this matter can be found in special sources; Here we note a few general points. So, the minimum indicator necessary for safe work with electric welding is 10 DIN ; as a consequence, this is the smallest value of maximum dimming that can be found in modern "chameleons". And most of these masks have higher levels of the greatest dimming — 11 DIN, 12 DIN, or even 13 DIN.

Darkening adjustment
The ability to manually select the degree of darkening of the filter in the chameleon mask. This feature is found mainly in professional models; it allows the welder to manually adjust the light transmission for specific conditions. The need to adjust the dimming is due to the fact that for some types of work (for example, TIG welding of ferrous metals), the brightness of the arc is relatively low, and in order to see the weld pool normally, dimming of only 8-9 DIN is enough instead of the usual 12 DIN or more .
Design features
— Backlight. Illumination system built right into the mask. This feature is very convenient when working in low light conditions: the backlight does not take up the hands (unlike hand-held flashlights) and does not create problems with wearing a mask (unlike headlamps), while the beam of light is always directed to where the welder's head is turned. On the other hand, such a system requires its own power supply. Therefore, it is used only in "chameleons", while the operation of the backlight additionally consumes battery power.
