1. An ultrasonic metal welding device comprising:
a compression chamber that is adjustable at least in height, and that is delimited on opposite sides by a section of a sonotrode as a first delimiting surface, and by at least one section of a counter electrode as a second delimiting surface;
wherein the section of the sonotrode is opposite the at least one section of the counter electrode;
wherein the sonotrode comprises at least one welding surface;
wherein the compression chamber closable or operable by a relative movement between the counter electrode and the sonotrode; and
wherein the counter electrode comprises:
at least first and second working surfaces separated from one another; wherein the at least first and second working surfaces have different geometries; and wherein only one of the at least first and second working surfaces is configured to close the compression chamber;
or,
at least two sections that are displaceable and selectable relative to one another, and that form at least two working surfaces; and wherein one of the at least two sections is configured to close the compression chamber.
