offers a blackout level of 4 in the inactive state, providing a clear field of vision before welding begins. During an arc strike, the mask automatically dims to a preset level between 9 and 13 DIN. Professional welders will appreciate the ability to adjust this range infinitely, allowing protection to be fine-tuned for different welding processes and current intensities. DIN standards determine the level of protection against intense arc light, and the 9-13 DIN range covers a wide spectrum of typical welding applications, from TIG welding of thin sheet metal to more demanding MIG/MAG or MMA work. For less experienced users, automatic dimming combined with adjustability provides optimal eye protection in a variety of welding situations, eliminating the need for multiple masks.

of the most important advantages of the OPTREL p550 neo mask is the use of a specially developed UV/IR filter with True Color View technology. Unlike standard welding masks, which often produce a greenish image, the p550 neo enables realistic color perception in the welder’s field of vision. For professionals, this means better color discrimination of welded materials, which is crucial when working with different metal alloys and allows a more accurate assessment of the weld pool and potential weld defects. It also improves overall work safety, allowing easier recognition of color indicators on welding equipment without having to lift the mask. This makes welding more precise and comfortable for each user.

offers a standard field of view of 50 x 100 mm. The dimensions of the ADF filter cartridge are 90 x 110 x 9.5 mm. For most professional and hobbyist welding applications, a field of view of these dimensions provides sufficient visibility of the weld pool and surrounding work area. It represents an optimal compromise between the width of the field of view and the weight and size of the mask, ensuring comfortable work without putting undue strain on the head and neck. Although masks with larger, panoramic fields of view are available on the market, this size is generally considered sufficient for many everyday welding tasks.

The OPTREL p550 neo mask is equipped with three independent sensors to detect the welding arc. Professional welders will appreciate the ability to adjust the sensitivity of the arc detection, allowing the mask to adapt to different working conditions, including welding at low current or in areas with limited access. A special “Super High” sensitivity setting is also available to ensure reliable arc detection even in the most challenging situations, such as low amperage TIG welding, where the arc may be less intense and more difficult for standard sensors to detect. The larger number of sensors, combined with the adjustable sensitivity, minimizes the risk of accidental flashes and ensures fast and reliable filter darkening, protecting every user’s eyesight.

the welder’s eyesight is a priority, which is why the OPTREL p550 neo mask features an extremely fast switching time from light to dark of just 0.100 ms (0.0001 second) both at room temperature and at an elevated temperature of 55°C. For the professional welder, this means immediate protection from the intense light of the welding arc when it is struck. This rapid response time minimizes eye exposure to harmful UV and IR radiation before the filter has time to darken, significantly reducing the risk of arc “glare” and ensuring the highest level of welding safety. This lightning-fast response is crucial to protecting the eyesight of both experienced welders and those just starting out in welding.

offers adjustable switching time from dark to light state in the range of 0.05 seconds to 1.0 seconds. Professional welders can adjust this parameter according to their preferences and the type of work being performed. A shorter brightening time may be preferred for spot welding or short welds, while a longer time may be more comfortable for longer welding cycles, reducing the effect of sudden brightening. In addition, the delay function protects the welder’s eyes from glare that may still appear for a while after the arc is extinguished. This adjustment allows the mask to be optimally tailored to individual needs and increases the comfort of each user.

is extremely important, especially during prolonged welding sessions. The OPTREL p550 neo mask features a lightweight design weighing just 495 grams, which minimizes the strain on the welder’s head and neck. The mask’s ergonomic shape and comfortable headpiece ensure optimal weight distribution, resulting in greater comfort. In addition, OPTREL has used a patented excenter system that allows the mask to be quickly and precisely adjusted to the shape of the head with a single movement. For professionals, this means a secure and stable seating of the mask without pressure, which is crucial for welding precision. The ease of adjustment and lightweight design make the mask comfortable for everyone to use.

is equipped with an efficient power system consisting of solar cells and two replaceable 3V (CR2032) batteries. Thanks to the new energy concept and energy-saving electronics with “Super-Sleep-Mode”, the battery life is an impressive 3,000 hours of operation. For professional welders, this means a long service life without the need for frequent battery changes, which increases convenience and lowers operating costs. The “Super-Sleep-Mode” automatically puts the mask into sleep mode when not in use, further minimizing power consumption. For any user, this is a guarantee that the mask will always be ready to work when you need it.
