The Optrel e684 (Blue) auto darkening welding helmet provides perfect view during welding with its Adaptive Shade Autopilot. Optrel‘s exclusive Adaptive Shade Autopilot automatically adjusts to the appropriate shade level as you weld. An additional brightness sensor immediately detects changes in arc intensity and adjusts accordingly. You remain perfectly protected, regardless of your current welding parameters. Automatic adjustment up to shade level 13 and features a 1/1/1/1 lens rating. Manual adjustment is no longer necessary – but it‘s available at the push of a button whenever you want it.
