Abstract: Various embodiments relate to a band flash butt welding machine by which it is possible to weld band faces of band ends of at least one band, in particular a saw band, to each other. The band flash butt welding machine comprises clamping elements for clamping the band ends. Furthermore, the band flash butt welding machine comprises aligning elements for aligning the band ends. The second clamping elements can be moved by a drive relative to the first clamping elements in the direction of a longitudinal axis. Two aligning elements are fixedly connected to one another by a coupling device, in particular a bridge part. The coupling device defines the relative alignment of the aligning elements. The second clamping element can be moved relative to the two aligning elements. This design is advantageous for a changeover of the band flash butt welding machine for band ends having a different geometry.
