微束等离子焊小电流问题的研究

RESEARCH ON SMALL ELECTRIC CURRENT IN MICRO BEAM PLASMA WELDER

介绍了研制的ＨＦＭＰ ５０型微束等离子焊机在实现其小电流的过程中所进行的一些研究，由子采取了一些特殊的措施，使该焊机的最小输出电流达到０．１Ａ时仍能稳定燃烧。

The article introduces our research work in the process of realizing small electric current in HFMP 50 micro beam plasma welder. As some special measures were taken, the minimal current output of the welder reached 0. 1 A.
