Features: Great Welding Effect - With full & smooth welding effect because of internal powder. With low melting point(647??~658??), great weldability and corrosion resistance, high thermal conductivity, high electric conductivity and excellent processing performance. No Need Solder Powder - You don't have to use other flux powder with aluminum alloy as the welding core and coating as the salt base. Very convenient and easy to weld. Widely Use In Life - Suitable for welding or surfacing welding alloy with high strength, good forgeability & good corrosion resistance. Very Wide Application - ?It is mainly used for argon arc welding and filling material for pure aluminum, connection with aluminium bus and guide rod of electrolytic aluminium plant and electric power, chemistry, food and so on. Light Weight & Small Volume - Size of 500*2mm & weight of 3.5g, very easy to bend & carry. Features: Great welding effect,with low melting point.

Specification: Material: Aluminum Length: 50cm Diameter: 1.6mm/2mm Package includingo 10/20/50 x Aluminum Welding Rods How to Use: Step 1: Clean and polishe 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. 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.
