Hoki Electric Desoldering Pump 220V 40WDesoldering pumps, sometimes known as solder suckers, are manually operated devices that remove solder from printed circuit boards. The desoldering pump is built with a double ring double open and "vacuum" button, which makes the sucking power incredible whether you are right or left handed. You may use the desoldering pump by simply cocking it and hitting the trigger button with one hand when you are ready. Desoldering wick and desoldering pumps are
