DNZ3 series three-phase secondary rectifier welding machineDetailed product description：

Characteristics of three-phase secondary rectification welding machine:
The three-phase secondary rectification welding machine has a compact structure. The welding machine adopts three epoxy cast fully sealed solder mask transformers and three sets of high-power diodes, which can output a large welding current. The maximum short-circuit current is not less than 70000A, and the welding current is not affected by changes in the secondary circuit. Suitable for the military and aerospace industries. The welding cylinder of this welding machine adopts a thin film cylinder with auxiliary stroke, and front and rear linear guides to ensure its good guidance. The auxiliary stroke is controlled by hydraulic oil circuit, which is convenient and accurate. The cylinder recovers quickly and works smoothly, which helps to improve the sensitivity of the welding machine during welding and effectively ensures sufficient welding pressure.  

The entire welding process is automatically controlled by the control box. The welding power on time is precise, the parameter adjustment is convenient and intuitive, making the operation easier and easier to learn. At the same time, the welding machine has an automatic compensation function for grid voltage fluctuations, which can fully ensure the welding quality of the welded parts.
