1. A device (10) for thermally joining workpieces, comprising:
a torch (1);
an extraction unit (2) for extracting fumes that are produced during welding, cutting or soldering processes; and
at least one sensor (3) for determining position and/or changes in the position of the torch (1) and/or of a reference point in space relative to a reference position of the torch (1) and/or of one of the workpieces that is to be processed, wherein the volume flow of extracted fumes is controlled or regulated indirectly by the extraction unit (2) acting at the torch (1) as a function of the determined position of the torch (1) and/or of any one of the changes in the position of the torch (1) determined by the at least one sensor (3).
