Abstract
A welding device for the sealing welding of thermopolastic hoses (184), includes a clamping device (12) with at least two clamping jaws (122, 124), of which at least one is movable and between which a hose (184) which is to be welded can be clamped, wherein the clamping device (12) has a heating devices (38; 40; 64) which is coupled to a control unit (30) and is configured to heat the hose clamped between the clamping jaws (122, 124). The invention is distinguished in that the at least one movable clamping jaw (122) is actuable with a controllable, bidirectional actuator (32, 34; 42-52; 54, 56, 58) which is coupled to the control unit (30) in such a manner that the clamping pressure acting on the hose (184) can be adjusted independently of the heating device.
