Abstract

High frequency electrical heating apparatus in which metal parts (10) are heated as they are advanced, either for annealing or forge welding purposes, and in which the electrical heating current is supplied by a solid state D.C.
to A.C. inverter (2-5, 8) through a load matching and frequency control circuit (13) which maintains the desired load current and current frequency with changes in the load impedance caused by the metal parts (10) as they are advanced.
