The e684 welding helmet has an autodarkening filter (ADF) lens that fully automates protection through its Adaptive Shade Autopilot technology.
- Automatically adjusts its shade level as the arc current fluctuates
- High-definition lens with Class 1 angular dependency provides a clear, crisp, true color view
- Twilight ADF Technology restores light more naturally, presenting a smoother transition to the eyes
- Cooling helmet design reflects light and heat, keeping welders 23% cooler compared with unpainted or dark-colored helmets
- Compatible with the e3000 powered air purifying respirator
- Darkens from shade levels DIN 4/5-13, and is suited for grinding when set to shade level DIN 4
