Optrel E684 Welding Helmet The optrel e684 is the perfect welding protection gear for demanding joining processes of aluminium, nickel-chromium alloys, special metals as well as steel. Thanks to the infinitely variable shade range of SL 5 to SL 13 the optrel e684 is is suitable for all electric arc welding as well as grinding processes. The optrel e684 is the welder‘s loyal companion, especially for industry applications such as vehicle & railway construction, agricultural & construction machinery, steel/machinery/tank/vessel/plant construction, pipeline & tube making, as well as shipbuilding and offshore. Do not settle for anything less! Adaptive Shade Autopilot Set it and forget it. The adaptive shade level control automati- cally adjusts the perfect shade level. An additional sensor that measures the arc intensitiy makes this autopilot function work. Therefore you always keep control of the appropriate trajectory regardless of which actual welding paramater is set. This allows you to stay focused on what really matters: Your welding process! Cooling Helmet Design Keep cool, even when the heat is on. Reflecting light and heat, the optrel e684’s special silver helmet keeps the welder’s head cooler by 23% compared to other unpainted helmets. In extreme environments, welders can work longer and be more comfortable in the long term. High Definition Viewing Superior viewing at every angle. Like viewing a high definition television, the optrel e684’s special HD lens provides a true color view to the welder. Its class 1 angular dependency allows welders to see the clearest, crispest view possible, enabling welders to concentrate more accurately on their weld. Wellness for the Eyes Groundbreaking technology prevents / re- duces eye fatigue automatically. Unlike other ADF lenses that rapidly re- turn to light, the optrel e684’s Twilight ADF Technology restores light more naturally, presenting a smooth transition to the eyes. This exclusive technology reduces eye fatigue on welders who are continuously welding, enabling them to work longer and safer. Daily Multi-Purpose use Darkening levels from 5 to 13 cover the majority of welding applications and with a protection level 4 in its general mode, the welder has a bright and well-lit view of the work-place. This feature predestinates the optrel e684 for grinding jobs as well.
