Abstract

1410042 Automatic voltage and current regulation MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 18 Oct 1972 [19 Oct 1971] 47885/72 Heading G3X A supply regulation system for spot-welding apparatus as disclosed in Specification 1391822 is modified by the inclusion of a high frequency blocking filter circuit 4 connected to phase shifter 1. The operation of the filter is such that compensation is provided during transient variations in the load, such as the switching in of additional welding devices. (For Figure see next page)
