Abstract

The invention provides a plasma column compressor. The plasma column compressor comprises a compression system and a matched cutting system, wherein the compression system comprises a compression current source, a compression sleeve and a compression lead, and is used for compressing an original plasma column; the matched cutting system comprises an original cutting current source, a cutting lead, a cutting torch and a workpiece, and is used for cutting a metal tube plate. Since the plasma column can be thinned by compressing, and energy is centralized, the advantages of high response speed, narrower notch, reliability and stability in running and the like are realized, and the cutting quality is closer to the lower limit level of precision cutting and laser-like cutting.
