Adaptive Shade Autopilot
The adaptive shade level control automatically adjusts to the perfect shade level. Let me say that again so it sinks in. The Optrel e684 has an autopilot feature that automatically detects the amperage settings your using and automatically adjusts the shade of the lens so you don't have to stop and manually make the adjustments. Going from grinding to MIG to TIG is no problem and no manual adjustments are needed. The Optrel e684 has an additional sensor that measures arc intensity and will automatically adjust the shade as the arc changes. This is a groundbreaking, unique feature that you will absolutely love.
High Definition Viewing
Similar to your new high definition television, the e684's special HD lens provides the truest color on the market. Its Class 1 angular dependency allows welders to see the clearest, crispest view possible, enabling you to better concentrate and make your weld wiht more precision.
Unlike other adaptive lenses that rapidly return to light, the Optrel e684 uses a twilight feature that restores light more naturally after you're done with your weld, presenting a smooth transition to your eyes. This unique, Optrel-exclusive feature will reduce your eye fatigue and help you work longer and safer.
