The OPTREL Crystal 2.0 mask owes its uniqueness to the groundbreaking Crystal Lens Technology 2.0 (CLT 2.0). This innovative technology, thanks to its unique UV/IR filter design, enables the welder to experience color vision in a remarkably realistic way, which dramatically differentiates it from traditional greenish tinted filters. For the professional welder, tangible benefits include significantly improved visibility of fine details and weld edges, which is crucial for perfect results. What’s more, CLT 2.0 enhances workplace safety by enabling continuous and comfortable observation of the surroundings in record-breaking DIN 2 brightness, minimizing the risk of trips and accidents in the workplace. Reducing eye fatigue is another major benefit, resulting from a more natural and sight-friendly image. This makes welding less stressful, even during long sessions. Finally, the ability to weld with unprecedented precision translates into higher quality work. CLT 2.0 is not only a significant improvement in the quality of vision, but also a fundamental change in the approach to work, allowing many activities to be performed without the need to constantly lift the mask, ultimately saving valuable time and reducing the risk of mistakes. The ability to continuously observe the surroundings in a clear DIN 2 condition significantly increases the welder’s situational awareness and minimizes the risk of dangerous situations.

The OPTREL Crystal 2.0 mask is equipped with a highly advanced and intelligent Autopilot mode that automatically and smoothly adjusts the shading level over a wide range from DIN 4 to DIN 12 depending on the current intensity of the light emitted by the welding arc. For the professional welder, this means hassle-free and optimal eye protection without the need to take a break from work and manually adjust the settings, significantly increasing comfort and safety. What’s more, the Autopilot system also offers the unique possibility of individual calibration within ± 2 DIN, allowing the user to adjust the degree of protection even more precisely to his personal preferences and the specific requirements of the welding task at hand. An additional, highly sensitive brightness sensor continuously monitors the intensity of the welding arc, ensuring optimal levels of protection in dynamically changing welding conditions. This advanced automatic shade adjustment not only contributes to comfort and safety, but also allows the welder to fully focus on the precision and quality of the weld being performed, without the distraction of manual adjustments to the settings.

The OPTREL Crystal 2.0 mask is equipped with the extremely comfortable Twilight function, which provides a smooth and gradual transition from the dark to the bright state of the filter at the end of the welding process. For the professional welder who often performs long welding sessions, this feature is invaluable, as it significantly reduces eye fatigue, which is often caused by sudden changes in light intensity in standard auto-darkening masks. What’s more, the brightening time is adjustable over a wide range of 0.1 to 2.0 seconds, allowing the welder to fine-tune this parameter to his individual preferences and the specifics of the job at hand. This gentle change in light intensity is especially important for prolonged work, minimizing the discomfort of sudden and unpleasant changes in lighting for any welder, whether experienced or novice.

The OPTREL Crystal 2.0 mask is equipped with an extremely practical grinding mode that can be easily and quickly activated by a convenient external control. When switched to this dedicated mode, the mask automatically sets itself to an extremely bright DIN 2 state, ensuring optimal visibility when performing all kinds of preparatory work, such as precision grinding, cleaning welds or preparing surfaces before welding. For the professional welder, this means significant time savings and increased work efficiency, as it eliminates the need to constantly remove the welding mask and put on a separate grinding visor. This integrated grinding mode not only improves productivity, but also enhances safety by ensuring that the face and eyes are always protected from potential grinding splatter and dust for each user.

The OPTREL Crystal 2.0 mask offers advanced infinitely adjustable sensitivity, allowing professional welders to adjust the mask’s response extremely precisely to the specific environmental conditions of the workplace and to the characteristics of different welding processes. What’s more, the mask is equipped with an extremely sensitive “Super High” mode, which is specifically designed for low-current TIG welding as low as 3 amps. As a result, even at such low currents, where the welding arc is very delicate and difficult to detect by standard sensors, the mask provides reliable and instantaneous filter darkening, guaranteeing optimal eye protection in any welding situation for even the most demanding welder.

A unique and highly practical feature of the OPTREL Crystal 2.0 mask is a patented movable sensor bar that allows the welder to manually reduce the detection angle of the welding arc from a wide range of 80° to a more concentrated 60°. Combined with three independent and highly sensitive arc sensors, this innovative feature significantly minimizes the risk of the filter being accidentally obscured by the welding arc of another welder working in the immediate vicinity. For professionals working in industrial environments with multiple welding stations where there is a risk of light interference, this smart solution significantly increases comfort and safety by eliminating the frustrating and potentially dangerous situations associated with unexpected darkening of the field of view.

Comfort is absolutely key, especially during prolonged and intense welding sessions. The OPTREL Crystal 2.0 mask features an extremely lightweight design weighing just 460 grams, which significantly minimizes the strain on the welder’s head and neck, helping to reduce fatigue and increase overall productivity. What’s more, the mask is equipped with a highly ergonomic IsoFit headpiece with a wide range of adjustments and replaceable soft inserts, ensuring an optimal fit to any head shape and guaranteeing maximum wearing comfort. In addition, the patented Excenter system further optimizes the mask’s balance on the head, ensuring a stable and secure fit without uncomfortable pressure, even during prolonged use by any welder. The mask’s design has also been rethought for comfortable wearing of corrective glasses, which is important for many users.

The OPTREL Crystal 2.0 mask offers a number of additional features that significantly increase its versatility and comfort for professional welders. The settings memory function allows you to save your preferred shading and sensitivity parameters, allowing you to quickly and easily restore your favorite configurations. Compatibility with OPTREL’s advanced PAPR (Powered Air Purifying Respirator) systems provides reliable respiratory protection against harmful welding dusts and fumes, which is crucial in environments with elevated levels of pollution. In addition, the mask provides effective protection against hazardous welding spatter and harmful welding fumes, further enhancing the level of occupational safety for each user.
