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. 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 will naturally rely on the thermal conductivity of the base metal.
