Abstract

The automatically centering clamping fixture with two sliding electrode holders is used in welding. The fixture has a hydraulic actuator for the upper electrode holder and an adjustment device for relative positioning of both electrode holders. The arrangement has a compensating spring whose force is adjusted with relatively high precision. The spring is exposed to the effects of the welding process only to a slight extent and this spring is relatively easy to replace. The arrangement has a long compensation spring built into one of the holders and this spring acts on both holders. This spring is held especially in the upper holder in a guide tube, to ensure smooth return of the holders to the initial position and can be adjusted with high precision due to its length.
