Delivering Swiss Made innovation and technology, the optrel Ready automatic welding helmet is the perfect solution for students, Do-It-Yourselfers, and everyday welders. With its adjustable shade level 4 (9-13) and customizable sensitivity adjustment, the optrel Ready offers optimal protection for most welding applications. With its IR and UV protection (even in inactive state) and its sturdy yet lightweight helmet shell design, the Ready comfortably and safely protects the eyes and head of the welder. Continuously variable sensitivity control allows the sensor sensitivity to be adapted to the surroundings and workplace. This function can also be used if welding at low amperages and the ADF is not darkening.
