Elecxlink Copper Aluminum Welding Rods 20 Pack 9 8in 25cm Universal Low Temperature Copper Aluminum Welding Cored Wire for Electric Power Chemistry

Product Specification: Type: Copper Aluminum Welding Rods Material: Copper Aluminum Color: Silver Diameter: 2mm / 0.08inch Length: 250mm / 9.84 inches How to use Step 1: Cleaning and polished the physical surface. Step 2: Heating the surface of the base material, until the temperature of the base material to the operating temperature of 716--788? (380--420 ?), so you can rely on the base metal heat transfer welding wire to form welds, should not use the flame to burn wire directly, 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 base metal heated to the appropriate working temperature, and then use the wire back and forth friction melting to form a weld. Step 4: Use propane gas to weld small object, use industrial gas or induction heating device to heat and weld big object, natural slow cooling after welding. Package Includes: 20 x 25cm Copper Aluminum Welding Wire.
