This technology is at the heart of the e684 and is revolutionizing the approach to eye protection. A dedicated brightness sensor continuously measures the intensity of the welding arc and adjusts the shade level in real time, fully automatically, in a smooth range from 5 to 13. The system eliminates the need for manual adjustments when changing welding current, method or position, ensuring perfectly adjusted protection every second of the job. Unlike stepped systems, the infinite adjustment prevents eye fatigue and allows you to focus fully on the task at hand. An investment in Autopilot is an investment in full focus on the weld, higher productivity and the elimination of errors resulting from incorrectly selected protection.

The 1/1/1/1 certification according to EN379 is a guarantee of the highest possible optical quality that can be achieved in a welding filter. The first number ‘1’ stands for optical precision, eliminating image distortion (magnifying glass effect). The second ‘1’ stands for the absence of light scattering, which prevents fogging. The third ‘1’ guarantees absolute uniformity of darkening over the entire surface of the filter, with no lighter spots. The last ‘1’ ensures consistent vision quality regardless of the viewing angle, which is crucial when welding in forced positions. This is the technical pinnacle that allows you to see the weld pool with unparalleled clarity. This optical class directly translates into less eye fatigue, better process control and the ability to make more precise welds.

Standard filters go from dark to bright instantly, which can cause temporary glare through the glowing metal just after the arc is extinguished. The Twilight technology in the e684 visor solves this problem by introducing a smooth, gradual brightening of the filter from dark to bright state. The timing of this transition can be adjusted to suit personal preference and the specifics of material cooling. This process mimics the natural adaptation of the human eye to changes in illumination, significantly reducing strain and stress on the eyes. This is a fundamental function that protects the eyes from light shock, increasing comfort and safety, especially during prolonged work and tack welding.

The e684 visor shell has been designed with modularity and future expansion in mind. It is fully compatible with Optrel e3000X respiratory protection systems, as evidenced by the existence of a dedicated e684 PAPR version. As a result, when working conditions require superior protection against welding fumes and dust, there is no need to replace the entire visor. Simply purchase a dedicated air supply system and integrate it with your existing helmet, creating a fully certified kit with respiratory protection. It’s an investment in flexibility and safety that allows you to adapt your equipment to growing requirements without the expense of buying a whole new set.
