Un3 Series Pipe Resistance Butt Welding Machine

Un3 series copper tube and aluminum tube butt welding machines is one kind of resistance butt welding equipment specially designed for copper tube and aluminum tube inserting method welding, it can replace the high-voltage flash welding machine with lower and old technology. The system adopt programmable logic controller(plc) as the action logic controlling unit; adopt special microcomputer welding controller as the welding process control unit; adopt the high-quality aluminum alloy cylinder and high-precision oil bearings integrated with high-precision lathe lever to make precise machinery actions. It has the reliable welding quality, easy and simple control and adjustment, high productivity, no gas leakage phenomenon, and some other excellences. The computerized controlling box with input voltage and output current constant and balance system can guarantee the machine produce mass weld in the same shape and quality.
