摘要

The device has a transformer (9) and an alternating voltage generator (11), which supplies the primary coil (10) of the transformer with an alternating voltage (UP). The mold stamp (6) and the metal workpiece (3) or the solder (2) are electrically connected to the secondary coil (14) of the transformer.
