Abstract
Spark melting machine has a transformer with power connections and pri. and sec windings. Mobile jaws and fixed jaws are provided for the workpiece, connected by the power connections to the sec windings. An automatic advance speed regulator for the mobile jaws, and a supplementary mechanism for the mobile jaws acting on the advance mechanism, are also provided. During welding, the regulator carries 2 AC to DC current convertors, 2 potentiometers, 2 commutators synchronised at 2 posns, an amplifier for zeroing the indicator and an electric motor. The 1st current convertor is branched to the transformer primaries and the 2nd is shunted to the secondary windings. The potentiometers are connected to the 1st current collector output, and the commutators are branched such that for one of their posns. the amplifier input is in series with the 2nd current convertor output and the 1st potentiometer output, while the amplifier output is connected to the reversible electric motor whose shaft is kinematically joined in sliding contact to the 1st potentiometer; and for the other posn of the commutators, the amplifier input is in series with the 2nd current convetor output and the 2nd potentiometer output, while the amplifier output is connected to the automatic advance speed regulator.
