What Is the PCB Welding Wire Fixture?
The PCB welding wire fixture is a third-hand tool for electronics work. A weighted base keeps it stable, adjustable arms with alligator clips hold your PCB or wires in place, and flexible goosenecks let you position everything exactly where you need it for soldering.
At $12, this is one of the cheapest quality soldering aids on AliExpress. It's the kind of tool that every electronics hobbyist, repair tech, and maker needs — and most don't own one yet.
How Does the Fixture Work?
Place the weighted base on your workbench. Adjust the flexible arms to hold your PCB at the right angle. The alligator clips grip the board edges securely. Now both hands are free — one for the soldering iron, one for the solder wire.
Key Features
- Weighted base — won't tip over during work
- Flexible goosenecks — position arms at any angle
- Alligator clips — grip PCBs, wires, and components
- Adjustable height — works with boards of any thickness
- Compact design — folds flat for storage
