A common fault in soldering irons is the breaking of the heating wire.
First, the simple repair method: the joint is spliced, but after this connection, the spark is often caused by the loose contact, and the joint is broken after a short time.
Second, the quick repair method: remove the heating wire from the cylinder, first remove the oxide near the fracture, and then splicing tightly, after splicing, sprinkle a little mixed powder of glass and electric ceramic around the joint (put the two according to 6 : 1 Grinding), after installation, the power is melted for a few minutes, and the powder adheres to the joint. In this way, the joint will not spark and it will be more durable.
There is a quick and reliable repair method: remove the heating wire from the cylinder, first remove the oxide near the fracture, and then splicing tightly. After splicing, sprinkle a small mixture of glass and electric porcelain around the joint (both Grinded at 6:1), after being installed, it is energized for a few minutes, and the powder melts and adheres to the joint. In this way, the joint will not spark and it will be more durable.
Electromagnetic relay is an electronic control device that has a control system (also called an input loop) and a controlled system (also called an output loop). It is usually used in an automatic control circuit, which actually uses a smaller current and is lower. The voltage is an "automatic switch" that controls large currents and higher voltages. Therefore, it plays the role of automatic adjustment, safety protection and conversion circuit in the circuit.
