📝 Product description
The FNIRSI HS-02A is a portable smart soldering iron in pen format with up to 100W heating power. It is powered via USB Type-C and supports the PD and QC fast charging protocols - so it runs on a notebook power supply, a travel adapter or a PD power bank. The working voltage can be selected in four levels (9 / 12 / 15 / 20 V), and the maximum output can also be limited from 10 to 100% so that even weaker power supplies remain stable.
The temperature is freely adjustable from 100 to 450 °C and is precisely controlled. Three preset channels (ex works 300 / 330 / 360 °C) can be switched through by pressing OK; you can choose the increment of the arrow keys between 1 and 50 °C. The 0.96-inch IPS color display shows the actual temperature, target temperature, active preset channel, working voltage and heating output.
The HS02A tips are significantly longer than the HS-02B at 9 cm total length and have a 2.5 Ω heating core. This provides reserves for large soldering points, ground surfaces and thick strands, and you can also access deeper components. The tip is tinned in around 5 seconds. The piston can be grounded via the antistatic connection - important for sensitive semiconductors.
⚙ Features in detail
- Operation: three buttons (OK, left, right). A short press on OK changes the preset channel, a long press switches off the heating (one-button standby).
- Voltage selection: 9 / 12 / 15 / 20 V, factory setting 20 V.
- Power limitation: 10-100% in 1% increments, factory setting 65%.
- Adaptive performance mode: automatically determines how much power your power supply delivers in a stable manner.
- Step size: Adjustable from 1 to 50 °C (factory setting 5 °C).
- Temperature calibration: Can be readjusted at three base points, values are saved automatically.
- Sleep and standby mode: 1-60 min each (factory setting 30 min), sleep temperature 100-200 °C.
- Left/Right Hand Mode: the key assignment for plus and minus rotates with it.
- Display and sound: Unit °C or °F, brightness in 10 levels, volume 1-10 or sound off.
- Firmware update: via USB-C on the PC - the piston reports itself as a drive, simply copy the file.
- Factory reset: resets all settings.

ℹ Without power supply and without battery. The HS-02A does not have a built-in battery and requires an external power source. For full performance, a USB-C power supply with PD and 20 V / 100 W is recommended; On weaker power supplies or PD power banks, the piston works with correspondingly reduced performance.
🧰 Care and safety
- Heat the new soldering tip to 250 °C and tin it before using it for the first time.
- After working, leave a thin layer of solder on the tip - this protects against oxidation.
- Only use the cleaning sponge damp, not wet.
- Do not use fluxes that contain a lot of chlorine or acid.
- When soldering, do not use the tip as a lever or hit it.
- Only change tips when cold; If it is difficult to move, use it by turning it slightly.
⚠ Danger: The soldering tip gets hot up to 450 °C - do not touch it. Keep the device away from children, protect it from moisture and unplug it when not in use for a long period of time. It is normal for the handle to heat up slightly during operation.
