Title:
SOLDERING IRON DEVICE
Document Type and Number:
Japanese Patent JPH09305240
Kind Code:
A
Abstract:

To improve the efficiency of soldering operation by selecting proportional integral and derivative control(PID control) and proportional control(P control) according to the contents of the soldering operation.

This device is provided with a temperature sensor 4 which detects the temperature of a heater 3 and a bit 2 when the bit 2 is heated and outputs it as measured temperature. A one-chip microcomputer 1 performs the PID control or P control over the power supply to the heater 3 according to a control program, set temperature, and a control constant stored in a ROM. Namely, the device has a switching mode for the control system of the heater 3 as one input mode and one of the temperature control systems of the PID control and P control is selected with a parameter changeover switch. An EEP ROM 24 stores, for example, the proportional constant, integral control, and derivative constant of the PID control system as a control constant and also stores the proportional constant of the P control system.
