ABSTRACT:
A pressing tool (13) includes a fluid pump (4), a cylinder element (5) arranged connecting with this and a piston which can be slid forward in the cylinder element (5) by pressure fluid of the fluid pump (4) and reset by a return spring (20a). A piston rod (6) is passed out to the cylinder element (5) as an activation part. The pressing tool (13) is moreover outfitted with a position measuring device (12, 12a;112, 212, 212a) which measures without contact which makes the piston position continuously detectable over a positioning range free of disturbance and with a presence sensor (52). The presence sensor (52) verifies the presence of a jointing clamp (51) and issues an indicator signal in the event that a jointing clamp (51) is missing or improperly fastened and shuts the pressing tool (13) off following a delay period to the extent that no orderly inserted jointing clamp (51) is yet available. The pressing tool (13) can also characterize the quality of the extrusion on the basis of the comparison of a detected maximal piston end position with a specified piston position range value.
