FAQs
What power adapter do I need for the FNIRSI HS-02A?
You need a power adapter or power bank that supports USB Power Delivery (PD) or Qualcomm Quick Charge (QC) protocols, with a voltage output between 9V and 20V, and a minimum wattage of 45W for good performance, ideally 65W or higher up to 100W for maximum capability.
How do I change the soldering tip?
Allow the iron to cool down completely. Unscrew the heating element nut and carefully pull out the old tip. Insert the new HS-02A-B series tip and re-tighten the nut securely.
What is the temperature range of this soldering iron?
The temperature can be adjusted from 100°C to 450°C (180°F to 842°F).
How do I put the soldering iron into standby mode?
The FNIRSI HS-02A features a one-touch standby mode. Refer to the user manual for the specific button combination or sequence to activate this feature.
Is the soldering stand included?
Yes, a mini soldering stand is included in the package along with the soldering iron, a tip, a power cable, and a tool bag.
Can I use any USB-C charger?
No, you must use a charger that specifically supports PD or QC protocols and outputs the required voltage (9-20V). Standard USB-C chargers without these protocols will not provide enough power.
How heavy is the soldering iron?
The FNIRSI HS-02A is very lightweight, weighing only 61g.
Troubleshooting
Soldering iron not heating up
Ensure the power source is connected securely and supports PD/QC with adequate voltage and wattage (9-20V, up to 100W). Verify the power cable is not damaged.
Temperature is unstable
Check for a stable power connection. Ensure the ambient temperature is not extremely low or high. Clean the soldering tip.
Display is dim or not visible
Confirm the power supply is active and providing sufficient power. If the issue persists, contact customer support.
Tip is not holding solder
The tip may need to be seasoned or replaced. Ensure the temperature is set correctly for the solder type being used. Clean the tip thoroughly.
Pros and Cons
Pros
- Fast heating and stable temperature control
- Compact and lightweight for portability
- Clear, informative HD display
- Supports modern fast-charging protocols (PD/QC)
- Ergonomic design for comfortable handling
Cons
- Requires a compatible PD/QC power adapter for full functionality
- Small size might be less ideal for very heavy-duty, continuous soldering

Setup, Compatibility & Care
Setup: Connect the included DC to Type-C power cable to the soldering iron and then to a compatible PD/QC power adapter or power bank (sold separately). Ensure the power source meets the voltage and wattage requirements (9-20V, up to 100W). The iron will power on and display the default interface.
Compatibility: The HS-02A soldering iron is compatible with HS-02A-B series replacement tips. It requires a power source that supports USB Power Delivery (PD) or Qualcomm Quick Charge (QC) protocols within the 9-20V range. Standard USB-A power adapters are not sufficient.
Care: Keep the soldering tip clean during use by wiping it on a damp sponge or brass wool (not included). After use, allow the iron to cool completely before storing. Clean the exterior body with a dry or slightly damp cloth; avoid harsh chemicals. Store in the provided tool bag to protect the iron and tip.
