Meet the Solder Ninja Pen — the ultimate USB-powered soldering iron for reliability and precision. Compatible with Weller’s extensive RT Micro tip catalog, it’s versatile enough for tasks ranging from large ground planes to submillimeter microsoldering. With hot-swappable tips, an adjustable temperature display, and a lightweight design, the Solder Ninja Pen is ideal for both professionals and hobbyists looking for portability without compromising quality.
Crafted from anodized, machined aluminum, the Solder Ninja Pen is built for durability. High-quality components, such as a tip connector rated for 5,000 cycles and a Würth Elektronik USB-C connector rated for 10,000 cycles, ensure long-lasting performance. The pen’s body design also provides mechanical stress relief, adding to its resilience.
The Solder Ninja Pen is compatible with 24 Weller RT Micro tips, covering tasks from microsoldering to large copper planes. Each order includes a 1.3 × 0.4 mm chisel tip, suitable for most applications. Additional tips with different geometries and use cases can be purchased separately below. For the complete list, refer to the official Weller catalog.
The Solder Ninja Pen operates from 7.5 W (1.5 A @ 5 V) and can negotiate up to 45 W, making it compatible with various power sources, including wall chargers, power banks, and laptops. Solder wherever you are, without limitations.

PCBWay manages the production and assembly of circuit boards. The body is machined from aluminum and anodized by a trusted supplier who delivered the first batch of pre-production units. Acrylic for the display window is provided by a separate supplier, and buttons are 3D-printed in resin. Packaging, designed for reuse as a carrying case, is produced by local company Durolle Emballage. All parts are shipped to France, where we assemble and test each unit.
