1. Energy saving. The radiator flash butt welding machine uses two 125KVA welding resistance transformers as the power source, pneumatic pressing, upsetting, and no hydraulic station. Compared with other single-phase AC welding resistance transformers using two 315KVA And two welding machines with a power of 18KVA hydraulic station, UN-250AB welding machine can save electricity up to 78℅.
2. Low requirements for power grid. Only 250KVA power grid can be satisfied.
3. High welding precision. Using programmable controller PLC and imported stepping motor to control the flashing process, the burning amount and burning speed can be accurately set; the welding current is controlled by the microcomputer welding resistance controller. The center distance error of the film head after welding It can be controlled within ±0.2mm, which is convenient for subsequent assembly and welding.
4. Automatic centering function. Ensure that the distance between the two ends of the pipe column and the two ends of the piece is the same before welding, so as to ensure the same amount of burning at both ends.
5. High welding efficiency. Since the workpiece is pressed by the double force cylinder, its reaction speed is significantly faster than that of the hydraulic cylinder.
6. Convenient operation and maintenance services. Since there is no hydraulic station, the product has fewer debugging points and fault points, and there will be no oil leakage.
