HIGH FREQUENCY HEAT TREATMENT DEVICE

摘要

PURPOSE:To provide a high frequency heat treatment device of a simple configuration which permits widening the adjustable range of the output to a warm keeping coil. CONSTITUTION:To an inverter 16 a heating coil 14 is connected through the first tap-equipped matching transformer 18 and a matching capacitor 19, and a warm keeping coil 15 is connected parallel with the heater coil 14 through the second tap-equipped matching transformer 23. Only the output to the warm keeping coil 15 is adjusted by the tap 23a of the second matching transformer 23.
