Key features
- Automatic helmet for industrial use Telwin Roundview suitable for all types of MMA, MIG-MAG and TIG (>2A) welding. Optical class 1/1/1/1. Solar cell operation.
- Maximum protection and vision: darkening adjustment (DIN 3/5 ÷ 9/9÷13). 180° viewing area with fixed dimming side openings. 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.
- “GRIND” mode (grinding): blocks darkening of the mask to carry out protected grinding operations in total safety.
- Comfortable use: light and comfortable, it is fitted with a headgear adjustment system for perfect fit and protection. Extended throat guard for protection.
