Solder Lead-Free Flux Welding Wire Sn99.3 Cu0.7 Tin Iron Wire 0.8mm 800g

Features: Solder lead-free flux welding wire Sn99.3 Cu0.7 800g High insulation resistance, little residual. Good welding performance to reduce welding time, improve welding efficiency Low corrosion, low melting point, fast welding speed, reduce the thermal shock caused by welding to components After welding, a protective film is formed on the surface of the solder joint to slow down the oxidation of the solder joint, and keep the solder joint bright The solder wire is widely used in electrical soldering, circuit maintenance, cell phone circuits, computer motherboards etc. Specs: Weight: 800g Diameter: 0.8mm Tin: 99.3%; Copper: 7% Flux: 2.0% Working Temperature: 250℃-300℃ Package Contents:1*800g Lead Free Solder WireHow to Use:1. In order to obtain a good welding effect, the parts to be welded must have weldability and keep the metal surface clean, use a suitable soldering iron or soldering stand2. After the solder iron is electrified, when the temperature of the iron head rises to the operating temperature, the welding operation can be carried out3. In welding operations, the operator's head should be 20cm away from the parts to be welded4. Not used for a long time or when the assignment is finished, cover the soldering iron with a layer of tin and then turn off the power switch to protect the iron head and prolong its service life5. The working area shall be equipped with suitable air purification equipment
