FNIRSI HS-03 Plus Soldering Iron

Whether you’re working at your desk, performing field repairs, servicing equipment, or working on precision electronics projects—the FNIRSI HS-03 Plus is up to the task in any of these situations. A high-capacity, replaceable battery ensures complete freedom of movement without cords, and USB-C charging lets you keep working without worrying about the device running out of power. Instant heating, a wide temperature range, and an intelligent heat stabilization system guarantee comfort and high precision during every soldering job. The compact design, featuring a clear IPS screen and an ergonomic grip, ensures the device fits perfectly in your hand even during extended use.

Full mobility and two power options

The built-in 2600 mAh battery allows you to use the soldering iron completely cordlessly, and its replaceable design extends the device’s lifespan and enables quick battery replacement when needed. When the battery needs recharging, simply connect it to a power source via the USB-C port and continue soldering. This makes the HS-03 Plus ideal for both servicing devices in the workshop and performing repairs on-site.

Instant Readiness and Precision

The advanced heating system reaches operating temperature in just 7 seconds, so you can start working almost immediately. With a temperature range from 100°C to 450°C, the soldering iron is suitable for both delicate electronic parts and SMD components, as well as more demanding applications requiring high temperatures. Temperature stability is ensured by an advanced PID control system, which effectively minimizes temperature fluctuations even under heavy load, ensuring repeatable and precise results.

Smart features that streamline daily work

Five available temperature presets allow you to instantly switch between the most frequently used settings, significantly speeding up the completion of subsequent tasks. The easy-to-read 0.96-inch IPS HD screen displays key information about temperature, power, and the current operating mode in real time. The automatic sleep and standby modes, with adjustable durations, help extend the tip’s lifespan and reduce energy consumption. The sleep function can be set from 30 seconds to 60 minutes, while standby mode can be set from 1 to 60 minutes. The well-designed control system accommodates both right- and left-handed users, automatically adjusting the button logic to match your preferred usage style.

Comfortable Design for Precision Tasks

The device’s housing is designed for comfortable use, even for many hours at a time. The ergonomic, silicone-coated grip enhances grip security and improves comfort, and the high-quality F210 tips with a 2.10 Ω core ensure very fast heat transfer and high precision when soldering small electronic parts and SMD components. Thanks to its combination of portability, smart features, and professional precision, the FNIRSI HS-03 Plus is a reliable tool for both hobbyists and more demanding users.
