随着生产的发展,我厂等离子切割铝板及不锈钢的厚度不断增加。过去是采用氮气作为等离子切割气体。当切割80毫米铝板时,采用KM—1型等离子切割机,配三台AB—500直流焊机作电源,切不开上述铝板。为解法这一问题,我们对氮氢等离子切 With the development of production, the thickness of our factory plasma cutting aluminum plate and stainless steel is increasing. In the past, nitrogen was used as a plasma cutting gas. When cutting aluminum plate 80 mm, the use of KM-1 plasma cutting machine, with three AB-500 DC welding machine for power, can not cut the aluminum plate. To solve this problem, we cut the nitrogen-hydrogen plasma
