PARALLEL SYSTEM OF INVERTOR TYPE RESISTANCE WELDING MACHINE

摘要

PURPOSE: To provide an invertor parallel system which uses a standard invertor, and is simply capable of parallel operation while connecting each invertor with several transmitting lines. ;CONSTITUTION: In the invertor type resistance welding machine, in which the electric power converted from commercial AC to DC by a converting circuit is converted to the prescribed AC power, plural invertor type resistance welding machines of the same constitution are connected at each respective invertor through a welding transformer 10, a secondary side of this transformer 10 are connected in directly parallel, further a welding sequence processing part 2, which is provided with the function for capacity-up through synchronizing signal and communication means, is provided. By not making up capacity up of a single machine but connecting a standard capacity machine in parallel, capacity is increased in relatively simple way.;COPYRIGHT: (C)1996,JPO
