50 Pack Solution Welding Flux-Cored Rods Welding Rods 50cm Universal Low Temperature Copper Aluminum Welding Cored Wire

How to use: Step 1: Cleaning and the surface. : Heating the surface of the base material until the temperature of the base material to the operating temperature of 716--788 Fahrenheit (380--420 Celsius) so you can rely on the base metal heat transfer welding wire to form welds should not use the 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.
