450V4700UF电子元件 全新螺丝脚电解电容器 450VDC YADACON 雅达康

The adjustment of the working voltage of the welding machine, in addition to the primary 220 / 380 voltage conversion, the secondary coil also has tap conversion voltage, at the same time, there is also the adjustable core to adjust the input of the iron core, the more the magnetic circuit, the more it enters. The lower the welding voltage. The electrode used in manual arc welding is made up of coating and core. During welding, the electrode acts as an electrode, on the one hand, it acts as an inductive current and ignites an arc, which produces a c***tant and stable arc between the electrode and the basic metal to provide the necessary heat for melting welding. On the other hand, the electrode is added to the weld as the filling metal, and becomes the main component of the weld metal. Therefore, the composition of electrode and the quality of electrode will directly affect the chemical composition, mechanical properties and physical properties of weld metal. In addition, the welding rod has great influence on the stability of welding process, weld appearance quality, welding productivity and so on.
