Mask "Chameleon" - maximum convenience for welding work

Almost gone are the days when welders worked with welded shields that were held in front of one hand, while the other hand needed to cook the part. The usual shield can be seen only in small workshops or when carrying out infrequent household work. For professionals and those who conduct welding on an ongoing basis, welding masks of new generations, including the mask "Chameleon", have long been invented and produced.

It is often an elegant helmet with a built-in light filter, while the latter is fixed in the headband and is not lifting, but can be removable and replaceable. The principle of the light filter, which has a welding mask "Chameleon", is based on the use of a complex design of polarized films, liquid crystal components, supplemented by an infrared and ultraviolet filter. Placed under a protective glass when connected to a lithium battery and a solar battery, this design automatically produces a light shade depending on the lighting conditions. And the light emitted during welding works, let's just say, is simply unbearable for the human eye due to its extreme brightness.

Mask welder "Chameleon" in addition to the main function - the optimal lightening - also has the ability to diffuse reflected light, which also positively affects the eyesight. A small drawback of the design is that the light, passing through several layers, dissipates somewhat, which reduces visibility.

The Chameleon mask has a number of characteristics that need to be considered when buying it, including:

• Optical class (from 1 to 3), which determines how geometrically clearly the objects are seen through the "layered" filter;
• Light scattering - the turbidity of the filter;
• Homogeneity - degree of uneven shading;
• Degree of shading depending on viewing angle;
• Turn-on time-shows how quickly the light filter is turned on when welding begins. The professional mask "Chameleon" has this indicator no more than 50 microseconds.

The light filter of the mask must necessarily have certification and qualification for a particular type of work. In the absence of these characteristics, it is better not to buy a mask. It is believed that high-quality filters are produced by such companies as Speedglass, Optel, Otos, Tekmen, Shain and Balder. They have international certificates guaranteeing quality, convenience, ergonomics and reliable vision protection. Sometimes manufacturers buy the above filters for welding masks of their brands, but this does not always guarantee the high quality of the final product. Therefore, it is better to buy the original mask "Otos", "Shain", etc.

For those who cook a lot, the best purchase will be a mask "Chameleon" with removable, not built-in batteries, because Their service life is limited to 2-3 thousand jobs, after which the elements must be replaced. Agree that it is much easier to replace it, if the welding mask design does not need to be opened.
