Solder pump from Weller is a lightweight, antistatic, hand-operated tool used for safe and effective suction of solder. To help you remove solder, the solder picks up by sucking it up via a spring-loaded piston that is released by a push button and primed by a piston. The extension springs are located outside the vacuum chamber, which helps prevent the solder tip from sticking and extends the life of the solder butt.
