Abstract

The invention relates to ultrasonic welding tongs (10) for performing ultrasonic welding on a tubular electrically conductive welding medium (20), wherein a first welding jaw or a second welding jaw and a welding-medium stop device (21), which delimits a welding-medium holding space (19) formed between the welding jaws, are each electrically conductive and arranged electrically isolated from each other, the electrically conductive welding jaw and the electrically conductive welding-medium stop device forming components of a safety circuit in such a manner that a welding process including a closing of the welding jaws is triggered after the safety circuit has been closed by the formation of an electrical contact between the electrically conductive welding jaw and the welding-medium stop device by way of the welding medium.
