The soldering table iron was broken. Using the constant temperature of the soldering iron, ordinarily I am not used to. It was said that the thermocouple of the thermostatic iron core was broken, and I thought of the industrial thermocouple that had been removed before, so I changed it with ordinary soldering iron. Here I didn't draw the detailed circuit, it was just the wiring and added an LED to indicate heating. The effect was just ok but it really saved soldering iron. And it is better to use this temperature device in the high power point.
