Abstract
The invention relates to a spot welding rod for the resistance welding of workpieces, the rod comprising a drive, which displaces the pincer arms and is configured by a spur gear and a connecting rod that is connected to the gear, the spur gear being connected to one pincer arm and the connecting rod to the other pincer arm. The invention also relates to a method for adjusting the pressure of a spot welding rod of this type. The aim of the invention is to provide a spot welding rod of this type with a simple, compact, modular construction, whose drive requires minimum maintenance and which permits a high number of spot welds. To achieve this, the connecting rod is connected to the spur gear outside the center of the latter, in particular at a defined distance to the central axis of the spur gear by means of a bearing assembly, the latter executing a curved movement during the working operation. A compensation element for compensating workpieces of differing thicknesses is located between the connecting rod and the pincer arm.
