ABSTRACT:
In a device for welding thin metal sheets passing thereunder and, more particularly, a stationary, water-cooled welding device for welding the lengthwise edges of a metal band formed into a tube, under protective gas, with the aid of one or more non-fusing electrodes (10) located in the welding head, each electrode (10) is held by an electrode clamp (5) in a burner housing (1). The electrode clamp (5) is held in the burner housing by a clamp holder (3). A tube-shaped clamping rod (7) is located in a central passage of the clamp holder (3). The electrode (10) is held by a slotted end of the tube-shaped clamping rod (7). This enables the electrode (10) to be pulled upwards out of the clamp holder (3), together with the clamping rod (7).
