20PCS Low Temperature Aluminum Welding Solder Wire Brazing Repair Rods 2500mm

Description

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 wire to the operating temperature of 380 degrees -400 degrees, so you can rely on the parent metal heat transfer welding wire to form welds, should not use the flame to burn wire, 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 aluminum base metal heated to the appropriate working temperature, and then use the wire back and forth friction melting to form a weld, only with a metal brush melt welding wire to weld at the 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
