FNIRSI HS-02A is a compact smart soldering iron with up to 100 W of power, offering fast heat-up, precise PID temperature control, and universal power input (USB-C PD, QC, and DC 9–20 V). With features such as adaptive power management, automatic sleep mode, and ESD protection, it is ideal for electronics repair, workshop use, and field work.
FNIRSI HS-02A is a modern digital soldering iron designed for fast, clean soldering of connectors, thicker wires, and delicate electronics. It combines high power with smart control, keeping the temperature stable even under load and minimizing the risk of overheating sensitive components.
Power can be supplied via USB-C Power Delivery, Quick Charge, or standard DC in the 9–20 V range. This means you can use it with a charger, power bank, laptop, or bench power supply—an excellent choice for mobile service and work away from the bench.
Main advantages and features:
- Maximum power 100 W for fast heat-up and strong thermal headroom
- Range 100–450 °C for wide use (from fine SMD to more robust joints)
- Segmented PID control and control accuracy < 2% for stable temperature
- Adaptive power management – automatic adjustment to the power source and protection of both tip and components
- Automatic inductive sleep mode + manual standby mode with a single press
- ESD protection with grounding option for safer work with sensitive electronics
- 0.96" color IPS display and physical buttons for quick settings
- Temperature presets (CH1/CH2/CH3) for instant switching between tasks
- Durable body made of CNC-machined aluminum and silicone, non-slip handle
