Technology Details
⚙️? ShadeTronic® Autopilot – Intelligent Protection Adjustment
ShadeTronic® technology is an intelligent system that analyzes the brightness of the welding arc in real time and automatically selects the optimal shade level from 5 to 13. This eliminates the need to manually adjust the filter when changing the method, current or welding position. The system constantly ensures that your eyes are protected with exactly the level of shading required at any given moment, minimizing the risk of glare and visual fatigue. It’s an investment in work continuity and uncompromised safety, allowing you to focus solely on weld quality, not equipment settings.
?PerfectOptical Class 1/1/1/1 – Crystal Clear View.
The e684 cartridge offers the highest possible optical classification of 1/1/1/1 according to EN379. This means no image distortion (the first “1”), no light scattering and haze (the second “1”), uniform obscuration over the entire surface of the filter (the third “1”) and excellent visibility even at an angle (the fourth “1”). Such a specification guarantees an absolutely clean, clear and optically flawless image of the welding pond and the surrounding area. Choosing a cartridge with a class of 1/1/1 is a guarantee of the highest optical quality, which is the foundation of precise welding and eye protection at a professional level.
?True-Color View Filter – Realistic Image of the World of Work
Unlike standard filters that give images a greenish tint, True-Color View technology provides near-natural color perception. The specially designed UV/IR filter transmits a wider spectrum of colors, dramatically improving the visibility of details, red LEDs on equipment or markings on the material. As a result, the welder has full control over the process, can guide the torch more precisely and identify possible defects in the weld faster. Investing in a True-Color filter is a direct result of higher work precision and less eye fatigue during multi-hour tasks.
⚙️⏳ FadeTronic® Technology – Smooth Filter Brightening
Patented FadeTronic® technology revolutionizes the way the filter returns to brightness after welding. Instead of a sudden, abrupt brightening, the system provides a smooth, gradual transition from darkness to brightness in an adjustable time of 0.1 to 2.0 seconds. This allows the eyes to gently adapt to the change in light, significantly reducing fatigue and discomfort, especially during intense tacking or short welding cycles. It’s an investment in eye health and comfort that improves productivity and allows you to work longer without feeling fatigued.
