Rosfix Soldering Tip with Built-in Heater T12-B Integration of heater and temperature sensor: T-12 series tips combine a heating element and a temperature sensor into a single element called a tip, which facilitates precise temperature control during soldering. Accurate temperature measurement: The temperature sensor (thermocouple) is placed very close to the soldering tip, which guarantees precise temperature measurement during the entire soldering process. Fast Heat-Up: T12 tips feature fast heat-up, reaching 300°C in less than 10 seconds, making it quicker to start and more efficient. Electrical Contacts: The tip is terminated with electrical contacts, enabling efficient energy transfer for temperature stability and efficient soldering. Quick Hot Change: The T12 tip snaps onto the soldering iron for quick hot change, increasing work efficiency and reducing downtime. Safe Replacement: Thanks to the quick-change T12 tip changer, you can safely change tips using a heat-resistant mat, minimizing the risk of burns and damage. Fits all soldering stations compatible with T12 tips.
