Leader Glass----- Clear Protective Glass Introduction

The rectangular plates are usually produced in shades number 8-14, it is possible to deliver them also in shades number 3-7. Welding glass with a vacuum coating of metallic oxides are produced in shades number 8-15.

Welding circles filters we have delivered usually in diameter 50 mm in shades number 3,4,5,6,7 and 8, it is possible to produce as well as others diameters and in the highest shades numbers. All glasses are produced in thickness from 2.4 to 3.2 mm.

The recommended use of protective welding filters of rectangular and circular shapes is given in Tables:

The rectangular plates are used for electric arc welding, eventually for plasma welding.

The circular welding glasses and pinto-shapes set into goggles are used for flame welding and for hard soldering. The lower protective grades are designed for crane operators and handling in welding workshops.

The metalized welding with extremely high current values, for methods MIG, MAG, TIG and plasma welding.

The welding filters mustn't be replaced by other glasses, which don't give the eye protection.

Leader Glass----- Clear Protective Glass Cleaning

Possible with water, alcohol and common detergents designed for washing of glass.

Leader Glass----- Clear Protective Glass Life time

The filter life-time is limited by a glass breaking. The filter is protected against flying metal drops during welding by the protective glass. The protective properties of the filter are unchanged and stable for the whole life-time. A damaged filter must be changed against the new one with the same protective grade as set in the mask or goggle originally.

Leader Glass----- Clear Protective Glass Protective effects

The human eye is endangered by the UV-radiation, i. e. the wave length under 400 nm, and by the IR-radiation, i. e. the wave length above 800 nm.

Ultraviolet radiation causes chemical changes in the cornea, in the white of the eye, in the eye lens and on the retina. The radiation of the wave length under 320 nm causes conjunctivitis, whereas the long-wave UV-radiation produces an eye fluorescence which reduces the contrast. UV-radiation of 300 nm and shorter irritates the skin and kills bacteria. The most harmful ultraviolet radiation for a living organizm is about 260 nm, where it is absorbed by nucleic acids in the cellular nucleus. The cells necrotise and proliferation is originated. The UV-radiation endangers the skin up to 0,6 mm deep, it means naturally also the skin of eye-lids and the eye front surface. These tissues become swellen.

Infrared radiation causes heat changes in the cornea, in the eye lens and on the retina. IR-radiation induces cataracts.

The protective welding filters SVAR protect safety against the above mentioned harmful radiation and make possible a sufficient distinction ability during operation because their major transmittance is in the wave length range of 560-565 nm, i. e. the maximal susceptibility of the human eye.

Leader Glass-----  Clear Protective Glass

Coated protective glass for welders coinst of metal coating, which is perfectly conected with glass. The coating reflects thermal rays well.

The products is suitable mainly for welding works carried on inside or of brilliant vessels, for extreme currents, for MIG, MAG, TIG and plasma welding.

The metal coating, reflects thermal rays, which are otherwise absorbed by protective glass and welding glass is not heated. Long-thermal rays using of uncoated welding glass is extreme conditions makes danger of over heating of eye in top that it is harmful.

Richness in colours of welding glass and spectral transmission curve are not changed, If we use welding glass with a vacuum coating of metaling of metallic oxides.

Suitability of application and protective properties are legalized by state testing laboratory in Aalen ( Germany) and satisfy of EN 166 and EN 169.

Delivered sizes are mostly 110 x 90 mm. max size is 220x200 mm
