FNIRSI HS-01 Intelligent Soldering Iron Tips

These replacement internal-heating soldering tips are designed specifically for the FNIRSI HS-01 smart soldering iron. Whether you are assembling a high-amp 6S racing drone or repairing a micro whoop in the field, having the correct tip profile is critical for clean, reliable solder joints. The internally heated core ensures rapid heat-up times and fast thermal recovery when dealing with thick copper traces and large ground planes on flight controllers.

Key features

• Fast thermal recovery: Internal heating element design rapidly replaces lost heat when soldering large copper masses like 4-in-1 ESCs.
• Oxidation-resistant plating: Prolongs tip life and maintains efficient heat transfer even under sustained high temperatures.
• HS01-B2 (Conical): A fine-point tip ideal for precision work on tiny receiver pads, UARTs, and thin signal wires.
• HS01-KR (Knife): A broad, bladed tip that maximises surface area for thick 12-14AWG battery leads, XT60 pigtails, and motor pads.

Specifications

• Compatibility: FNIRSI HS-01 Soldering Iron
• Heating type: Internal heating core
• Available profiles: B2 (Conical), KR (Knife)

For standard FPV builds, the KR knife tip is highly recommended for power leads and ESC motor pads due to its excellent thermal mass transfer. Keep the B2 conical tip on hand for fine-pitch components, VTX wiring, and delicate ELRS receiver installations where avoiding solder bridges is essential.
