MAA ENTERPRISE Aluminium Welding Rod Welding Rod  (Pack of 3)

Injector Valve Grinding Rod Specification: Material: Aluminum Color: Silver How to Use: Step 1: Clean and polish the physical surface. Step 2: Heat the surface of the base material, until the temperature of the wire to the operating temperature of 380??400?, 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. NOTE: 1. The surface of the base metal must be clean. Packing : 1 x 3 welding road
