Low Temperature Aluminum Welding Rods 10/20/50Pcs 500mm x 2mm 3.5g No Need Solder Powder Product Description: Material:Aluminum Color:Silver Number of Pcs:10PCS 20PCS 50PCS Melting Point:647°~658° Diameter:2mm / 0.08 Length:500mm / 19.7 Weight:Approx. 3.5g / 0.12in (One Aluminum Welding Wire) Package Included: A1: 10Pcs x Aluminum Welding Wires A2: 20Pcs x Aluminum Welding Wires A3: 50Pcs x Aluminum Welding Wires How to Use: Step 1: Clean and polish the physical surface. Step 2: Heat the surface of the base material until the temperature of the wire to the operating temperature of 380°~400° so you can rely on the parent metal heat transfer welding wire to form welds should not use the flame to burn wire When the surface temperature of the base metal is sufficient the wire can flow well and penetrate into the metal capillary. Step 3: When repairing thin aluminum as long as the aluminum base metal heated to the appropriate working temperature and then use the wire back and forth friction melting to form a weld only with a metal brush melt welding wire to weld at the weld.
