1Effective oxidation performance is good, with good warming and expansion ability. 2Good activity, good welding performance to reduce welding time and improve welding efficiency. 3Low corrosion, low melting point, fast welding speed, can reduce the impact of welding on components. 4Less residual after welding, light color and high insulation impedance, excellent power, no special requirements can not be cleaned. 5High purity, oxidation resistance, after welding in the solder surface to form a layer of protective film, slow down the oxidation of solder joint, keep the solder joint bright. Item Type: Tin Wire Material: Tin Color: As Pictures Shown Wire Diameter: Approx. 1.2mm Weight: Approx. 1389g/49oz Model: Environmental 100g 1.2mm Flux content: 10% Melting point: 200 Welding current: 20A How to use: 1. When in use, in order to obtain a good welding effect, the welded part must be weldable and the metalsurfacemust be kept clean. Use a suitable soldering iron or soldering station 2. After the soldering iron is energized, the soldering operation can only be carried out when the temperature of the soldering iron tip rises. 3. During the welding operation, the operator's head should be kept at least 20cm away from the weldment 4. When not in use for a long time or after the operation is completed, put a layer of tin on the soldering iron tip and then turn off the power switch to protect the soldering iron tip and prolong its service life 5. The work area should be equipped with suitable air purification equipment 10 x Tin Wire
