The e684 welding helmet also has True Color technology, which allows for realistic color perception in light or dark states. It scores a perfect 1 rating for optical class, scattered light, homogeneity and angular dependence. The e684 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. Features • AUTOPILOT - Detection of the arc brightness and fully automated shade level adjustment from 5 to 13. Adjusts automatically to the changing light conditions of the current welding method. • Twilight Feature - gradually lightens lens when switching from dark (welding) to light state to ease eye fatigue. • TRUE COLOR - A specially developed UV/IR filter allows the realistic color perception typical of Optrel, bringing color to the welder’s world. TRUE COLOR passes more colors of the spectrum through compared to standard "green" spectrum welding lenses. • Lens Image Quality 1 - optical class, 1 - scattered light, 1 - homogeneity, 1 - angular dependence • Patented Sensor Slide allows the detection angle to be reduced from 120 degrees to 60 in order to prevent the ADF from responding to welding nearby. • Overhead Welding - Unique Optrel® shell design prevents weld spatter slag. • Sensitivity Adjustment - allows operator to change lens switching sensitivity for varying ambient light conditions or outdoor welding in sunlight. • Grind Mode - Switch quickly and easily between weld mode and shade 4 grind mode using external controls. There is no need to remove the welding helmet to grind. • External Lens Controls include infinite shade 8 to 12 adjustment, delay and infinite sensitivity adjustment and allow for quick switching between weld and grind modes without removing the welding hood. • Patented Excenter perfectly centers the welding helmet when in open position for better comfort, balance and less neck fatigue. • Comfort Headband quickly and easily adjusts for size, forward position and top position. • Hard Hat Adaptable using the Optrel hard hat adapter.  Specifications Click the image below to view the full spec sheet Accessories
