Abstract
A welding protective mask (1) includes illumination equipment (3) for illuminating a work area. The illumination equipment (3) includes an illumination device (5), a detection device (8) for detecting an ambient light intensity, an energy storage (7) for electrically supplying the illumination equipment (3) and controller (6) for controlling an intensity of light radiated by the illumination means (5) according to the ambient light intensity. In a preferred embodiment of the invention the controller (6) is set up to detect a welding process with a flicker circuit and to switch off the illumination device (5) during the welding process.
