AUTOPILOT - Detection of the arc brightness and fully automated shade level adjustment from 4 to 12. Adjusts automatically to the changing light conditions of the current welding process.

TRUE COLOR passes more colors of the spectrum through compared to standard "green" spectrum welding lenses. Grind Mode - Switch quickly and easily between weld mode and shade 2.0 grind mode using external controls. There is no need to remove the welding helmet to grind. Sensitivity Adjustment - allows operator to change lens switching sensitivity for varying ambient light conditions or outdoor welding in sunlight.

Optrel's Autopilot automatically adjusts the shade level based on the brightness of the arc or flame. The auto-dark lens can also be operated in fully manual mode with infinite shade adjustment between shades 4 and 12 for a custom view of the arc.
The Crystal 2.0 welding helmet also has improved True Color technology, which allows for realistic color perception in light or dark states.
