Aluminum Welding Rods 20 Universal Low Temperature Aluminum Repair Rods Easy Welding Cored Wire for Electric Power Chemistry 2-4mm 10inch

Specification: Quantity: 20PCS Material: Aluminum Color: Silver Diameter: 2.4mm / 0.09" Length: 250mm / 9.8" Instructions for use of low temperature aluminum welding wire Step 1: Polish the surface by physical cleaning. Step 2: Heating the surface of the base material at the welding place until the temperature reaches the working temperature of the welding wire of 380 ° C - 400 ° C, so that the weld can be formed by the heat conduction welding wire of the base material. Do not use a flame to burn the wire, and only when the surface temperature of the base material is sufficient, the wire can flow well and penetrate into the metal capillary.. Step 3: When repairing the relatively thin aluminum, the aluminum base material is heated to a suitable working temperature, and then the wire is frictionally melted back and forth to form a weld seam. Only the metal brush is used to fill the weld to form a weld. Step 4: Use propane gas to weld s mall object, use industrial gas or induction heating device to heat and weld big object, natural slow cooling after welding. Operation attention detail 1. The surface of the base metal must be cleaned. Clean immediately, weld immediately. 2. The temperature of the base metal should reach 400 °C, including the temperature of the base metal during the welding process should also be maintained at 400 ° C, and the temperature can be high or low. 3. Avoid using flame to deliberately burn the welding wire. After the temperature of the base material reaches 400 °C, the welding wire wil
