450V2700UF电子元件 全新螺丝脚电解电容器 450VDC YADACON 雅达康

(4) various metallurgical reacti***, such as deoxidation, sulfur removal, phosphorus removal and so on, will be carried out after melting, so as to improve the weld quality and reduce the burning loss of alloying elements; (5) adding the needed alloy elements to the weld metal through the coating to improve and control the chemical composition of the weld metal to obtain the desired properties; (6) the casing is formed in the process of welding, the arc blowing force is increased, the arc heat is concentrated, the droplet is transferred to the molten pool, and the working principle of the welding process is accomplished, the current and voltage are reduced by the three-phase main transformer. The output current is controlled by changing the phase of the SCR trigger angle. Rectifier straightening
