Abstract

PURPOSE:To detect the disconnection of an electrode wire with remarkably high sensitivity, by providing a disconnection detection circuit which detects the disconnection of the electrode wire by phase relation with the pulse of a zero volt pulse generating means. CONSTITUTION:When the disconnection of the electrode wire 51 is generated, the influence of low resistance components in first and second heating resistors are eliminated in the positive half cycle of an AC power source 13, and a current phase advances by the influence of the capacitance component of temperature thermosensible resin 5, therefore, a pulse waveform whose phase leads by that of the zero volt pulse generating means 75 can be obtained. A control means 76 detects a phase difference between the zero volt pulse generating means 75 and a disconnection detecting means 104, or reads the state of the pulse of the disconnection detecting means 104 after a prescribed time in a digital way from the pulse of the zero volt pulse generating means 75, and detects the disconnection of the electrode wire 51. And the control means 76 holds the stoppage of the driving of a transistor 40 in a driving means.
