Butt welding machine is also called current welding machine or resistance welding machine. By using the resistance between the contact surfaces of the two workpieces, a low voltage and large current are used to instantaneously heat the contact surfaces of the two butting metals to melt and fuse. Butt welding machine uses resistance welding method and flash butt welding method to realize welding of various wires, rods, rings, plates, tubes and other profiles of low carbon steel, medium carbon steel, high carbon steel and non-ferrous metals. Its design is reasonable, its quality is reliable, its operation is convenient, its working place is flexible, and it is easy for the welder to master. Top calcining force, jaw distance, current can be easily adjusted according to needs, and can be automatically and manually fed. Suitable for wire drawing, nail making, cable and wire, steel wire rope, construction and other industries. Working principle: Radiator flash butt welding machine uses two 125KVA power frequency resistance welding transformers as the power source, both ends are pressed at the same time, discharge flashes, and forging are completed to complete the butt joint between two steel radiator heads and the middle oval tube. The burning amount, upset amount, and welding current are set and displayed by the PLC through the LCD screen.
