Contact usUN3 series butt welding machine is a special welding equipment for connecting copper and aluminum pipes. It can replace the special high pressure flash butt welding and soldering machine that were originally used. The system uses programmable.
The logical sequence controller (PLC) is the control unit for the action logic, and the special microcomputer welding controller is the control unit for the welding process. It uses high quality aluminum alloy cylinders and high precision oil pump bearings.
The precision machines use high-precision lightweight rods to ensure precise mechanical movements. It has the advantages of reliable welding quality, intuitive and easy operation and adjustment, high production efficiency, no welding leakage and no air, and high productivity.
It can store many different specifications and call up different specifications according to different pipe diameters. It is easy to operate and highly efficient. It is widely used in air conditioners, refrigerators, freezers, cold storage, compressors and other products.
