Product Description

UN Series Flash Butt Welding Machine Rebar Butt Welder Steel Rod Ring Chain Link Butt Welding Machine

Main Features for DC controller and transformer:

1.High quality,high efficiency,98% power factor,three-phase input load balancing,the impact on the user grid greatly reduced,DC input current,smooth,inductance is zero,1000HZ working frequency,time control precision is 1MS;
2.High-strength body structure,good rigidity,direct pressurizing mechanism,linear bearings used in the guiding structure enable good mobility;
3.Adopt high-speed  microprocessors,use intelligent optimal calculation method,LCD interface,can save 60sets welding schedule numbers,There are functions of switch display in both Chinese and English,provide external BCD call interface,system fault diagnosis alarm automatically.etc

Main Features for flash butt welding machine
1.The butt process starts when the two workpieces to be welded which are clamped by welding jams still not meet each other.
2.During the subsequence,move the welding jaws together slowly,the welding current density will increase,then the metal material in the gap between the jaws becomes molten,at the same time a shower of sparks also being emitted.
3.As the cross-sectional area in the welding becomes extremely hot,the motion is accelerated.
4.The flashing also makes the surfaces to welded together totally.
