ABSTRACT:
A safety device for irons used for models includes a control electrical circuit board accommodated within an iron and mounted with a temperature setting knob controllable by a variable resistor, a central processing unit, an output control device, a heater, a sensor, and an indicator having three light emitting diodes of three different colors. When power is on, the central processing unit will examine the control circuit to ensure that the iron is in a normal state before causing the iron to be heated to a set temperature. The central processing unit will keep on checking the control circuit and, once the temperature of the iron is sensed to be unstable or abnormal, the light emitting diodes will indicate trouble and power will be cut off to protect the control circuit board.
