Abstract: The invention relates to spot welding tongs with tong compensation, including a tong base body (4), two tong arms (6, 7) and a compensation unit (17) movably connecting one of the tong arms (6, 7) with the tong base body (4) and designed to convert a rotational movement into a linear movement, wherein the compensation unit (17) is composed of a drive unit (18) and a connector element (19), and the connector element (19) is eccentrically and movably fastened to an eccentric disc (23) fastened to the drive unit (18). In order to provide such spot welding tongs (1) with a compensation unit, which converts the rational movement into a linear movement, the connector element (19) is designed to be curved in an end region.

Abstract: The invention relates to a method and to an apparatus for operating a power source (1) connected to a manually actuated implement (4) by a user, wherein parameters of the power source (1) are set by way of operating elements (3) of an operating and display unit (2) and a movement of the implement (4) in the space is captured by way of an evaluation unit (9) disposed in the power source (1). In order to enable fast and rapid operation of the power source (1), even without removing a potentially present protective clothing of the user, it is provided for an operating function to be activated at the power source (1), whereupon the movement of the implement (4) in the space (6) is captured and a position of the implement (4) resulting from the movement is associated with the operating and display unit (2).
