Aluminum Soldering Tool Weld Flux Cored Wire Welding Rods 100-500cm Roll 1.5/2mm DESCRIPTION Aluminum Soldering Tool Weld Flux Cored Wire Welding Rods 100-500cm Roll 1.5/2mm Product Description: Copper-aluminum welding wire welding wire copper welding seam repair without tin Features: 1. Good welding effect: This welding rod is produced by a regular manufacturer. You can see from the picture that the welding rod itself is very smooth and shiny. Its welding effect is full and smooth! With flux powder inside. It has low melting point (about 420°C) good fluidity strong hardness and toughness and good sealing. It is unnecessary to use other flux powder. 2. Direct use: no need for any flux ready to use after opening the package! Very convenient! Solder easily. 3. The method of use is simple: first polish the welding parts of the copper and aluminum tubes with sandpaper (the paint oxide and oil on the metal surface must be cleaned) and move the welding torch to evenly heat the parts to be welded when the temperature reaches 420 ℃ (Medium temperature) When the temperature is left and right add copper-aluminum welding rod to heat and melt and evenly into the joint. After the weld is full remove the welding torch and cool. After cooling no further treatment is required. Although the flux residue is visible but non-corrosive Does not absorb moisture and adheres firmly. Product parameters: Size: 1.5mm / 2.0mm * 1000mm / 2000mm / 3000mm / 5000mm Can be welded at a temperature of 450-500℃ Suitable for maintenance: aluminum/iron/copper/stainless steel Package list: 1 *Copper aluminum welding wire
