The device (1) includes at least one folding bed (2) for receiving at least two metal sheets, folding jaws (3) which are functionally connected to associated folding jaw supports (4), at least one thermal jointing tool (5), and at least one mass electrode (9, 9′). At least the joining tool is not attached to the folding jaws, and the joining tool contains a lever oriented away from the folding bed as a linear feed device. The lever (6) has a center of rotation (10) outside the folding bed, wherein the joining tool can swivel in the manner of a knee lever into an operating and/or non-operating position.
