When an automotive repair involves solder, it often involves desoldering too. Removing old solder is a crucial part of preparing a component for a new soldered connection, and a desolder pump (often called a solder sucker) is the ideal tool for the job. It removes old solder with more speed and control than desolder braid and only costs a fraction of a full-on desolder station.
