Product description 
Under the operation of transformer, Cu-Al tube butt welding machine utilizes the general mains supply to lower the voltage and increase the electric current. Such kind of low voltage but large current will be transmitted from the electrode to the linked point of two work pieces. On the linkage, due to the resistance of work piece, high temperature will occur so the metal will therefore generates high heat to make the work pieces in molten condition. Thus, the purpose of welding the two work pieces is achieved.
