Nano Portable Soldering Tool

Found a new portable nano‑soldering unit. It houses a 5W plasma torch, a retractable alloy tip, and a self‑calibrating feed that auto‑detects material resistance; it disassembles into two parts with a single Allen key. I don't care that it's matte black; what matters is that it can be broken apart and reassembled with a torque wrench without leaving a smear of flux, like the coffee mug on my workbench. The unit reflows solder in two seconds, auto‑cools, and logs data to my handheld. This tool gives me immediate repair capability on the fly and cuts downtime from my projects. #MechanicsFirst 🔧
