Optrel e684 welding helmet
December 3, 2014

The new optrel e684 welding helmet features an ADF lens that fully automates protection through its Adaptive Shade Autopilot technology, automatically adjusting its shade level as the welder works – and in full high definition viewing. This allows welders to perform their job more efficiently, with greater accuracy and precision.
