Usage: 1. Clean and polish the physical surface. 2. Heat the surface of the metal material until the temperature of wire is up to the working temperature 380? to 400?. 3. The aluminum base metal is heated to the appropriate working temperature when repairing thin aluminum, and then use the wire  friction and melt to form a weld. 4. Use propane gas to weld small object and use industrial gas or induction heating device to heat and weld big one, you should cool it naturally. Packing List: 20 * Aluminum Welding Rods
