The Optrel® e684 meets the stringent 1/1/1/1 lens rating for the clearest, cristpest, and truest color view possible. Welding with the e684 is like watching TV on a 4K Ultra HD TV! The e684 also features Adaptive Shade Control, Twilight Technology, a variable Arc Detection Angle, sensitivity adjustment, a grinding mode, and an optional hard hat adapter. Designed for the serious welder, the e684 also promotes coolness and is available only in a heat reflecting silver color.
The Optre® e3000 PAPR System provides increased safety by continuously monitoring air flow by means of an integrated sensor during the whole welding process. Ideal in combination with the e684 helmet. Better comfort with adjustable three-level air flow of 150 to 250 l/min and a cooling effect even at the most extreme ambient conditions. Constant air flow thanks to smart sensor controlled electronics and a variable adjustment of air flow between the forehead and respiratory area.
The package includes the Optrel® e684 auto-darkening welding helmet, blower unit with hose, filter, battery, fabric belt, charger, and operating instructions.
Warrranty: 2 years from the date of sale for manufacturing and material defects, 6 months from the date of sale for the battery.
