FNIRSI HS-02B 100 W Smart Soldering Iron
100 W smart soldering iron with FNIRSI HS-02B tool kit
FNIRSI HS-02 is a new generation smart soldering iron that combines 100 W power, rapid heating, precise temperature control, and exceptional mobility. PD, QC, and DC (9–20 V) power support, adaptive power control, a 0.96" IPS color screen, ESD protection, and automatic functions make it a tool ready for use in both electronics service and in the field. This equipment is designed for people who expect maximum performance without compromise.
A clear advantage over a standard soldering iron
Compared to standard 60-65 W soldering irons, the FNIRSI HS-02 offers over 50% more power, up to four times faster tinning (2 s), and a sturdy CNC aluminum and silicone housing instead of ABS plastic. In addition, it offers features not available in cheaper models: adaptive power, preset temperatures, sleep mode, antistatic protection, and an included bag and stand. It is a premium tool that makes a real difference in everyday work.
Instant heating and stable operation under load
The maximum power of 100 W guarantees rapid heating of the tip and excellent temperature maintenance even when soldering massive wires, screens, connectors, and large soldering areas. The soldering iron reacts immediately upon contact with the component, which eliminates temperature drops and allows you to work faster, cleaner, and with greater precision.
Universal power supply – complete freedom of operation
With USB-C Power Delivery, Quick Charge, and classic DC 9–20 V support, the FNIRSI HS-02 can be powered from a mains charger, power bank, laptop, or workshop power supply. It is the perfect solution for mobile service technicians, field electronics engineers, and users who want a single tool for all applications – without location restrictions.
Adaptive power control – intelligence that protects
An advanced automatic power adjustment system analyzes operating conditions and dynamically regulates power consumption. This ensures that the soldering iron operates efficiently and stably, while protecting the tip, power supply, and soldered components. This provides real safety and longer equipment life, especially during intensive use.
Precise PID temperature control
The 100–450°C adjustment range and segmented PID control ensure fast heating, stable temperature maintenance, and instant heat recovery. Control accuracy below 2% allows for safe work with sensitive SMD and BGA circuits and precision electronics, minimizing the risk of overheating and damage.
Preset temperatures and convenient operation
The ability to save several temperature profiles (CH1, CH2, CH3) allows you to instantly adjust the soldering iron to a specific task. The clear interface, logical menu, and physical buttons make changing settings quick and intuitive, without interrupting your work and without unnecessary complications.
Automatic sleep mode – economy and safety
The inductive sleep function automatically lowers the temperature when the soldering iron is resting on the stand and immediately restores it when the device is lifted. This is not only convenient, but also reduces energy consumption, extends the life of the tip, and increases safety during operation.
ESD protection and robust design
Built-in electrostatic discharge (ESD) protection with grounding capability protects sensitive electronic components from discharge. The CNC-machined aluminum housing, silicone non-slip grip, and tip guard protect against burns and ensure durability, comfort, and a secure grip even during long hours of work.
