Features:1. EASY TO USE - Removes excess desolders parts faster and easier. Allows you to desolder your components and circuit boards without damage.2. ONE-HANDED USAGE - Whether you're right or left-handed, you can use the desoldering pumps by just positioning it and pressing the trigger button with one hand when ready.3. HIGH-QUALITY WITH POWERFUL SUCTION - Constructed with durable frame and a high-pressure vacuum that effectively removes solder from printed circuit boards.4. ALLOY-BRAIDED SOLDER WICKS - Precision weaving solder braid helps clean any spares solder on the pin away to avoid short circuits, especially in small, hard to reach areas.5. DURABLE DESOLDERING IRON TOOL - The body of the desoldering pumps is made of aluminum alloy, which is durable and can resist corrosion while having improved heat dispersion.Notice:1. Actual color may be slightly different from the image due to different monitor and light effect. Please allow 1-3cm deviation due to manual measurement.Specification:Size: as picture showPower: 30W/40WTin Suction Nozzle Diameter: 1.6mmTube material: aluminum alloyCable length: 1.6 metersHOW TO USE:Turn on the power and preheat for 3-5 minutesPush down the piston handle, point the tin suction nozzle at the soldering part; After the lead has melteds, press the control button, and observe the lead being sucked into the cylinderNOTES:1.Check whether the voltage is consistent. Too high or too low voltage is not conducive to use.2.Before using, spin the cylinder and the suction nozzle tight to prevent leakage. 3.Clear the solder impurities in the suction nozzle and the cylinder frequently, and add a little oil to the piston when needed.4.Every time after using, push the piston 3-4 times to remove any residue.5.It's normal that there is a slight smoke due to heating during the first time using the new suction pumps. It will naturally disappear after ten minutes.6.While operating, a natural cooling soldering iron base must be equipped and the suction pen should be placed in the iron base.This product has a ground wire which should be used along with a socket with contacts.includes:1 x Desoldering Suction Pumps
