Product description
The “TW20” model helmet is composed of a filter TW20B; furthermore, it is composed of transparent external and internal front guards. The helmet was designed to guarantee correct eye protection during welding, as well as providing the maximum performance both in facilitated assembly and the convenience and quality of use: it guarantees permanent protection against UV and IR radiation and sparks generated during the arc welding process.
Main features
- Automatic helmet for industrial use Telwin Grandview suitable for all types of MMA, MIG-MAG and TIG (>2A) welding. Optical class 1/1/1/1. Solar cell operation.
- Protection and greater vision: darkening adjustment (DIN 4/4 ÷ 8/9÷13). 150° viewing area. In addition to adjusting the sensitivity of the filter according to the welding process, there is also an adjustment of the delay time for switching from the dark to the light state after the arc has been interrupted, depending on the brightness of the workpiece.
- Vision quality for safe work without interruptions: The LCD liquid crystal filter automatically darkens on striking the welding arc and quickly returns to its transparent status when the arc is switched off; eliminating the need to lift and lower the helmet on each work break and thereby allowing the operator to work with hands free.
- Vivid colours: True Color technology enables work with more realistic colour vision, with clearer contrasts and greater definition of the image for more precise welding and less eye fatigue.
