Warm tips:
1 When welding, you must first clean up the oil on the surface of the workpiece, and then pay attention to the heating time. The heating temperature exceeds 600 degrees, and the copper tube will melt in 0.03 seconds, which is called sintering.
2. After welding, it is generally cooled with clean cold water. Avoid oxidation. Generally, nitrogen is passed into the tube to protect the tube from oxidation.
3. The brazing flame is divided into oxidizing flame, reducing flame and neutral flame. Generally, reducing flame is used for welding to ensure the quality of copper pipes.
4. Generally, do not pull the solder joints forcefully, because the solder will crack.
