Optrel e684 Silver Welding Helmet
Optrel e684 Silver Welding Helmet
The Optrel e684 is an auto-darkening welding helmet built for welders who switch between varied jobs and need a wide range of adjustment options. Its adaptive shade autopilot detects the amperage you are using and adjusts the lens shade automatically, so moving from grinding to MIG to TIG needs no manual changes. The HD lens delivers true color and a clear view, while the twilight feature restores light gradually after each weld to reduce eye fatigue.
