Elevating welding safety: How ADF and DIN shades transform protection and precision
16 febbraio 2025
In welding, the human eye is constantly exposed to extreme conditions. The welding arc generates intense light, ultraviolet (UV), and infrared (IR) radiation, all of which can cause severe and permanent damage if not properly shielded. While traditional helmets relied on fixed shade lenses, advancements in Auto-Darkening Filter (ADF) technology have revolutionized how welders balance protection, visibility, and precision.
The ADF lens employs liquid crystals capable of switching states instantaneously. When exposed to the arc's bright light, these lenses transition from clear to dark within milliseconds and return to clear once the arc is extinguished. This adaptability ensures welders can see their work clearly during setup and protect their eyes during the welding process.
Why DIN shades matter
Choosing the right DIN shade for your task ensures maximum protection and improves your ability to weld accurately and efficiently. The DIN shade determines how much light is filtered through the ADF lens. Selecting the appropriate shade is not just a matter of comfort—it’s critical for safety. Too low a shade risks UV and IR exposure, while a shade that’s too dark reduces visibility and precision.
DIN shades range from low levels for light cutting and grinding tasks to high levels required for heavy-duty welding with reflective materials. Modern welding helmets allow welders to customize shade levels to match the specific task and their personal preferences, ensuring both safety and efficiency.
DIN shades determine how much light is filtered through the ADF, balancing visibility and safety. For example:
DIN Shade | UV 313–365 nm | Visible light | IR-A (780-1400 nm) |
---|---|---|---|
DIN 3 | 2.8% | 17.8–8.5% | 9% |
DIN 8 | 0.025% | 0.16–0.061% | 1% |
DIN 13 | 0.00044% | 0.0012–0.00044% | 1% |
DIN 14 | 0.00016% | 0.00044–0.00016% | 1% |
Choosing the right shade reduces the risk of eye irritation or poor visibility, ensuring welders can work safely and efficiently.
Advancing optical clarity
Kemppi’s Vision+ Color ADF technology exemplifies how optical innovation can improve the welding experience. This technology enhances color recognition and optical clarity, reducing eye strain and improving accuracy. Welders can focus more effectively, experience less fatigue, and produce higher-quality work.
By integrating cutting-edge science with user-focused design, ADF lenses represent the forefront of welding protection, bridging the gap between safety and productivity.
