K-331 Desoldering Pump Solder Sucker Aluminum Metal Solder Removal Tool Vacuum Remover Soldering Iron Desolder Hand Welding ToolsProduct Information:Material: aluminum alloyColor: GrayBrand: KaisiModel: K-331Net weight: about 51gFeatures:Excellent performance: strong suction, anti-static, easy to clean, replaceable tips.Anti-clogging: The long ejector pin effectively prevents frequent use of clogged nozzles.High temperature resistant solder absorber: The nozzle made of high-quality nylon material is more temperature resistant than the ordinary nozzle.Powerful solder suction cups: Features a high-pressure vacuum that contributes to effective solder removal.Small and lightweight: Easy to carry, desoldering pumps can be used with one hand, either right or left.Strong suction power, can effectively prevent air leakage.Compact design for easy one-handed operation.How to Use K-331?Step 1: Press the tin suction piston down until it is lockedStep 2: Heat the solder with a soldering iron to make the solder completely liquid;Step 3: Move the nozzle of the pump next to the molten solder. Remove the tip and immediately cover the liquid solder pit with the nozzle of the pump. Press the release button.Step 4: Repeat this process if necessary.Tips for use:1. Ensure that the solder suction piston is well sealed. Before powering on, block the welding hole of the solder suction head with your finger and pressThe button of the lower suction head, if the piston is not easy to spring into place, it means that the sealing is good.2. When the tin tip is worn, it should be replaced with a new one.3. Solder paste dip a little rosin before contact with solder to improve solder fluidity.4. The head contact pad is slightly longer, when the solder melts, take the solder joint pin as the center, then stretch out clockwise to draw a circle, and then press the solder absorber button.Package includes:1 x K-3311 x hose
