Features:
* New
* Made of - materials,
* Wuxi copper aluminum stainless steel weld seam maintenance
* Good welding effect: its welding effect is full smooth! With the help of internal powder. It has low melting point, good fluidity, hardness toughness, good sealing. No need to use other flux powder
* Direct use: Any flux is really needed. Open the package use it! Very convenient! Easy to weld.
* Welding: Fi rst polish brass aluminum tube welding parts with sandpaper (you must clean the paint, oxides, oil, . on the metal ), move the welding gu n to evenly heat the welding parts, then continue to use the welding rod when the temperature rises to for 360 degrees. The copper-aluminum electrodes are melted evenly into the joint. After the weld is full, remove the cutting flashlight wait for it to cool down. After cooling, there is no need for further treatment. The flux is visible, but it is not , non-hygroscopic firmly adhered.
