Fnirsi Hs-02 Smart Soldering Iron 100W Portable - (Hs-02a comes standard with 6 heads)

The FNIRSI HS-02A Smart Soldering Iron 100W is a portable soldering tool designed for electronics technicians, makers, repair professionals, and DIY enthusiasts. Unlike a conventional fixed-temperature soldering iron, it provides adjustable temperature control and a digital display to help users manage heat during different soldering tasks.

With a maximum rated power of 100W and a temperature range of 100°C to 450°C, the HS-02A is suitable for a broad range of electronics work, including circuit-board assembly, wire connections, component replacement, and precision repair. Actual heating performance depends on the power supply, selected temperature, tip, and workload.

The HS-02A version comes with six interchangeable soldering tips—B, C2, I, JS, K, and KU—allowing users to select a suitable tip for different joint sizes and soldering techniques. Its 0.96-inch color screen displays operating information, while programmable temperature presets make frequently used settings easier to access.

Features

• Up to 100W power: Supports rapid heating when paired with a suitable power source.

• Adjustable temperature: Temperature settings from 100°C to 450°C for different soldering tasks.

• Digital color display: A 0.96-inch IPS screen for monitoring operating settings.

• Six interchangeable tips: Includes B, C2, I, JS, K, and KU tip styles.

• USB-C power input: Supports compatible external PD/QC power sources.

• Temperature presets: Three groups of preset temperatures for convenient adjustment.

• Intelligent functions: Includes sleep mode, automatic power-off, and child-lock functionality.

• Portable design: Pen-style construction for convenient storage and transport.

• External power operation: Does not require an internal battery; a compatible power source is necessary.

Applications

• PCB soldering and circuit-board repair

• Through-hole component soldering

• Electronic component replacement and rework

• Wire and connector soldering

• DIY electronics and prototyping

• Robotics and embedded-system projects

• Small electronic-device maintenance

• Precision soldering tasks using an appropriate tip

How to Use

1. Connect the power source: Use a compatible USB-C PD/QC power supply that supports the voltage and power requirements of the HS-02A.

2. Install the tip: Fit the appropriate soldering tip securely while the iron is cool and disconnected from power.

3. Power on the iron: Follow the manufacturer's instructions to start the device and select the required temperature.

4. Choose the correct tip: Use a fine tip for small joints and a broader tip when greater heat transfer is needed.

5. Prepare the joint: Clean the contact surfaces and apply suitable electronics solder and flux.

6. Solder carefully: Heat the joint and apply solder to the connection rather than relying on the iron tip alone to transfer molten solder.

7. Power off safely: Use the device's controls to shut down, allow the tip to cool, and store the tool securely.

Important Notes

• A power adapter is not necessarily included. Confirm whether your selected package includes the 100W adapter before purchasing.

• The 100W figure is the maximum rated power; actual power delivery depends on the connected power supply and operating conditions.

• Use a compatible PD/QC power source and suitable USB-C cable. An ordinary low-power USB charger may not provide sufficient power.

• The soldering tip becomes extremely hot during operation. Keep it away from skin, flammable materials, and children.

• Work in a well-ventilated area and avoid inhaling solder or flux fumes.

• Use electronics-grade solder and flux appropriate for the job.

• Disconnect the power source before changing tips or carrying out maintenance.

• Do not touch the tip until it has cooled completely.

• The six-tip configuration applies to the HS-02A version; HS-02B packages may have different tips.
