FNIRSI HS02 100W Heat Set Tool & Corded Soldering Iron Kit | 3D Printing & Electronics Repair

Two-in-one power for makers

The FNIRSI HS02 blends a heat-set insert tool with a corded soldering iron in a compact, multitask-ready package. It’s designed for precise insert installations in 3D-printed parts and plastics, while also offering steady soldering performance for small electronics repairs. The ergonomic grip and reliable corded power help you stay focused on the task, whether you’re refining a prototype or restoring a delicate board.

Power, temperature, and control

Delivering up to 100W of heat (9–20V), the HS02 maintains consistent performance across a range of tasks. It supports a temperature span of 212–842 °F (100–450 °C) and includes three preset temperature groups for quick switching between jobs. If a restart occurs, Adaptive Power Mode helps keep heat steady without guesswork, reducing downtime and frustration.

In addition to rapid warm-up, the tool’s compact control surface makes it straightforward to fine-tune settings as you move from inserts to soldering tasks, helping you complete projects with smoother transitions and less waiting time.

Smart, safe, and portable

Smart features include sleep mode, automatic power-off, and an optional child lock to fit daily routines and learning environments. The kit is designed for portability, and a dedicated storage case keeps everything organized for on-the-go use, whether you’re in a studio, workshop, or field repair.

• Sleep mode and auto-off conserve power when idle
• Child lock option adds basic safety for shared spaces
• Included storage case keeps the tools organized while traveling
