How to replace the electric soldering iron heating core

1. Disassemble the soldering iron first, and throw away the old heating core directly. The wires inside are burned out, and the plug part is burned out, and the wires have to be replaced.

2. Before installation, you need to put a heat-insulating bushing on the connecting wire. If there is no existing heat-insulating wire, unplug the bushing and install it.

3. Connect the pin first. Connect it directly to the tight spot and not slide it. You can use pliers to pinch it hard. If it slides, it will burn out easily.

4. Insert the pin back into the soldering iron seat and wrap one end of the connector with tape for insulation. This insulation must be done well, and then solder the new wire to the wire end of the soldering iron seat.

5. Just restore the soldering iron after finishing everything. The whole core replacement process is very simple. As long as the insulation treatment is done, there is no problem. A good electric soldering iron is very important for those who often do electronic production.
