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 a low melting point (about 420°C), good fluidity, strong hardness and toughness, and good sealing performance. No need to use other flux.
2. Direct use: no need for any flux, ready to use after opening the package! Very convenient! Easy welding.
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 around, add copper-aluminum welding rod to heat and melt and evenly  into the joint point. After the welding seam is full, remove the welding torch and cool down. After cooling, no further treatment is required. Although the flux residue is visible, it is non-corrosive, does not absorb moisture and adheres firmly.
