The True Colour filter uses specially designed optics that transmit a much wider color spectrum than standard welding filters. In practice, this eliminates the dominant green tint, allowing the surroundings and the welding pool to be seen in near-natural colors. Such image clarity enables the welder to accurately assess the fluidity of the metal, identify oxide colors and better control the entire welding process. It also reduces eye fatigue during prolonged work. An investment in True Colour technology is a direct result of higher weld quality and less strain on the eyes.

The neo p550 visor offers infinitely variable adjustment of the degree of protection from 9 to 13 DIN, allowing ideal adjustment for a wide range of welding methods and intensities. Adjustment is made via a convenient external knob, allowing you to change settings in real time without removing the visor. Whether you’re MIG/MAG welding at high amperage or precisely joining parts using TIG, you can always select the optimal level of shading for maximum visibility and protection. This is an investment in versatility and safety, allowing you to work effectively in a variety of conditions.

The Sensitivity adjustment function allows you to fine tune the sensors that detect the welding arc. This prevents accidental darkening of the filter caused by other welders nearby or by strong external lighting. On the other hand, the brightening delay (Delay) adjustment controls the time it takes for the filter to return to its bright state after the arc is extinguished. Setting a longer delay protects the eyes from the intense glow of a hot weld, which is crucial when welding with high currents. It’s an investment in personalized protection that adapts to your work environment and prevents eye fatigue.

The dedicated grinding mode, activated by an easy-access switch on the outside of the shell, is a key feature for productivity. When it is activated, the self-dimming filter is deactivated and locked at a fixed brightness level of 4 DIN. This enables a smooth transition from welding to preparatory and finishing work, such as grinding or cutting, without removing the visor. This ensures uninterrupted protection of the face and eyes from splashes and sparks. Investing in an external grinding mode is a direct boost to productivity and safety on the job site.

The p550 series visors, in keeping with Optrel’s philosophy, feature modular construction. This means that the key components, such as the shell and the auto-darkening cartridge (ADF), are interchangeable parts. In case of mechanical damage to the shell, there is no need to purchase a whole new visor. In addition, this model is fully compatible with dedicated magnifying lenses (diopters +1.00 to +2.50), an invaluable convenience for welders with impaired vision. It’s an investment in long-term usability and economy, allowing for easy repair and customization.
