ABSTRACT:
An apparatus for feeding wire at great distances having wire-feeding mechanisms connected by thyristor stages with phase control to generators of ignition pulses, and supplied by a common supply bus to a speed stabilizer in the first wire-feeding device, connected to the wire-feeding mechanism and the generator of ignition pulses. In a first embodiment the output of the generator of ignition pulses of the first wire-feeding device is connected by means of a synchronization bus to the inputs of the generators of ignition pulses of the second and the next-following wire-feeding devices. In a second embodiment the inputs of the generators of ignition pulses of the second and the next devices are connected to the outputs of formers of synchronizing pulses, the inputs of which are connected to one of the supply buses.
