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 .
Sensitivity adjustment
The ability to change the sensitivity of the sensors responsible for the operation of the light filter in the "chameleon". Thanks to this function, you can adjust the filter in such a way that it is guaranteed to turn on from the arc and at the same time does not react to extraneous light sources.
sensitivity adjustment is especially useful when there is numerous extraneous "flare" (for example, when several welders work close to each other, in bright sunlight, etc.).
Delay time adjustment
The ability to manually set the delay time between the disappearance of the arc and turning off the filter in the chameleon mask. Such a delay is highly desirable in the light of the fact that even after the arc is turned off, the heated metal continues to glow for some time; therefore, it is advisable not to turn off the filter immediately.
Adjusting the delay time allows the welder to independently choose the time to return to the non-working (maximally transparent) state.
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.
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.
