The invention relates to a device for metal welding, comprising a shielding element (1) which allows visual monitoring of the working process but protects the eyes from light radiation. The device comprises a video camera (5) which is directable towards the welding zone for recording the welding process in the form of video signals transmitted, via an image processing unit, to a video display unit (7), which the user is able to view and which is placed in or on the inside of the shielding element (1). The image processing unit reads process data from the video signals and presents the same via the video display unit.
