Low Temperature Easy Melt Aluminum Universal Silver Welding Rod Cored Wire 1.6mm Rod Solder No Need Solder Powder Weld Bar Description: Type: medicine core Material: aluminum Flux content: 20(%) Wire diameter: 1.6(mm) Melting point: 380(℃) Length: 330/380/500/1000mm Weight: 2(g) Operating temperature: hot temperature Welding current: 110(A) Specifications: 1. Good welding effect: the welding rod itself is relatively smooth, shining and its welding effect is full and smooth! It has low melting point (about 420 ℃), good fluidity, strong hardness and toughness, and good sealing performance. 2. The use method is simple: first use sandpaper to polish the welding parts of copper pipe and aluminum pipe (paint oxide, oil stain, etc. on the metal surface must be removed), move the welding gun to evenly heat the parts to be welded, when the temperature reaches about 420 ℃ (medium temperature), add copper-aluminum welding rod to melt when heated and flow into the joint point evenly, remove the welding gun after the welding seam is full, and cool down. No further treatment is required after cooling. Although the residue of the flux is visible, it is non-corrosive, does not absorb moisture and is firmly attached. 3. Product application: leakage welding of aluminum bottom oil tank cold instrument. Repair of cracks in aluminum parts of transmission box at the base of aluminum alloy engine block. Repair of cracked holes in fins of aluminum oil pan radiator. Aluminum fittings are missing blocks or worn in large areas for a second recast welding. Package Included: 1 * welding wire 1 * Weld Wire
