今年五月,浙江省鄞县栎社电讯厂从省科学器材公司宁波分公司引进生产 JYH-300型电弧焊、钨极氩弧焊两用的手工焊机技术。焊机采用钨电极,以氩气作为保护介质,电源为直流电,配有镇定变阻器。在电流变小时,电弧仍很稳定,它通过专用焊炝和电器控制,不必采用熔剂、焊剂仍能获得高质量的接头。该机应用范围广,特别适用于0.5
In May of this year, Zhejiang Yinxian Lishe Telecommunication Factory imported the JYH-300 type hand-welding machine technology, which is dual-purpose arc welding and TIG welding, from the scientific equipment company Ningbo Branch of Zhejiang Province. Welder with tungsten electrode to argon as a protective medium, the power supply is DC, with a varistor stabilization. When the current is small, the arc is still very stable. It is controlled by special welding torch and electric appliance, so it is not necessary to use flux. The flux can still obtain high quality joint. The machine has a wide range of applications, especially for 0.5
