Abstract

PURPOSE: To make it possible to exercise temperature control substantially with safety by manually resetting the self-holding of one thyristor which holds by itself automatically, and then by making the other thyristor reset its self-holding through the operation of a temperature detection circuit.
CONSTITUTION: A series circuit of heating wire 96 and thyristor 93 controlling the power feed of it is provided with the other series circuit of heating wire 99 and thyristor 94 controlling the power feed of wire 99; both circuits are connected in parallel being equalized in polarity and to those circuits, alternating-current power supply 1, power switch 2 and temperature fuse 3 are connected in series, thereby constituting a main circuit. Here, thyristor 94 holds by itself automatically and its self-holding is reset by manual switch 63; and the self-holding of thyristor 93 is reset through the operation of a temperature detection circuit of transistor 28. Consequently, temperature control can be exercised securely with safety.
