**Please be aware that this is the helmet shell only. It does not come with the Auto Darkening System**
The Optrel Crystal 2.0 auto-darkening welding hood features a shade 2.0 light state unmatched for colour and clarity. The Crystal 2.0 lens has fully automatic shade 4 to 12 arc brightness detection with a Twilight feature to gradually bring the lens back into the light state from the welding state, reducing eye strain. 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 arc view.
The Crystal 2.0 welding helmet also has improved True Colour technology, which allows for realistic colour perception in light or dark states. It scores a perfect 1 rating for optical class, scattered light, homogeneity and angular dependence. The Crystal 2.0 has external controls to switch quickly and easily from weld to grind mode and back again. Delay and sensitivity can also be controlled using the external knobs.
Does not include ADF Lens
