The 1/1/1/1 classification according to EN379 is the highest possible standard for welding filters, guaranteeing an image without distortion or optical defects. Each “one” refers to a key parameter: optical class (no distortion), light dispersion (no haze), uniformity of obscuration and angular dependence. In practice, this means that you see the welding lake and surrounding area with maximum sharpness and clarity, regardless of the viewing angle. An investment in a Class 1/1/1/1 filter is a direct investment in work precision, reduced eye fatigue and the ability to produce the highest quality welds.

ShadeTronic® technology is a fully automated shade level control system. An advanced light sensor constantly measures the intensity of the welding arc and adjusts the shade level from 5 to 13 DIN in real time, without any user intervention. This means that the filter automatically dims tighter when welding at high current and brightens at low current, providing ideal visibility and protection in all conditions. It’s an investment in work continuity and full focus on the task at hand, eliminating the need for manual adjustments and the risk of working with an incorrectly adjusted shade.

Unlike traditional filters, which give the image a strong green tint, True-Color View technology from Optrel provides a much wider spectrum of transmitted light. As a result, the colors seen through the filter are natural and realistic. The welder can accurately distinguish the colors of the weld pool, heat affected zone or markings on the material, resulting in better control of the process. This is an invaluable advantage that improves the quality of work and significantly reduces visual fatigue during multi-hour tasks.

FadeTronic® revolutionizes the moment of welding arc extinction. Instead of a sudden, abrupt transition from dark to bright, the filter brightens smoothly and gradually over an adjustable period of 0.1 to 2.0 seconds. This patented mechanism eliminates the unpleasant eye “glare” effect that often occurs after welding, especially during frequent tacking. It allows the eyes to comfortably adapt to changes in lighting. An investment in FadeTronic® is an investment in eye health and comfort, minimizing eye fatigue and allowing you to work longer, more efficiently.
