The E684 Welding Helmet from Optrel is fully automatic with HD quality.
Optrel’s exclusive Adaptive Shade Autopilot automatically adjusts the E684 auto darkening lens to the appropriate shade level as you weld – set it and forget it! It’s third sensor helps the E684 immediately detect changes in arc intensity and adjust accordingly. This allows you to stay focused on whether really matters: striking the perfect arc.
Reflecting light and heat, the E684’s special silver helmet color keeps the welder’s head cooler by 23% compared to other unpainted and dark helmets. In extremely hot environments, welders can work more comfortably over a long period of time. Like viewing an HD TX, the E684’s special high definition lens provides a true color view to the welder. It’s Class 1 angular dependency allows welders to see the clearest, crispest view possible, enabling welders to concentrate and make their weld with more precision.
Unlike other auto darkening lenses that rapidly return to light, the E684’s Twilight ADF Technology restores light more naturally, presenting a smoother transition to the eyes. This exclusive technology reduces eye fatigue on welders who are continuously welding enabling them to work safe and more comfortably.
The E684 is available with a model compatible with the NIOSH approved Optrel E3000 PAPR system. The E3000 features a high performance particulate filters (TH3) that protects welders from exposures to smoke, gas and other particulates.
