Usage:
First polish the welding parts of the copper and aluminum tubes with sandpaper (the paint oxide and oil stains 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 degree Celsius (medium temperature) around, add copper-aluminum welding rod to heat and melt and evenly flow 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.
