Use one compact tool for electronics soldering and fitting heat-set threaded inserts into 3D-printed parts. This FNIRSI HS-02A kit combines an adjustable-temperature soldering pen with a threaded tip adapter and seven interchangeable brass insert heads.
A compatible external power supply is required. A mains charger, USB-C charging cable and threaded insert nuts are not included. Available heating power depends on the supply and cable used. Change tips only after they have cooled. Choose a temperature suitable for the plastic and insert, work with ventilation, and use the stand between operations.
