An electric fusion coupling for coupling thermoplastic pipes contains a heating coil 2 and has a resistance 6 with a value, which is selected according to the power that is to be fed to the coil, which is connected between a main terminal 4 and an auxiliary terminal 5. The control device is designed to register the resistance value and to supply electrical current to the coil over a predefined period, which is automatically adjusted according to the resistance value. <IMAGE>
