本机采用变频调速，调速范围宽，能切割不同厚度的废钢，水平、垂直方向切割行程大。

So it can cut different thickness scrap steel. Its cutting route is very long in horizontal and vertical direction.

在作大厚度切割时，变频跟踪应适当调慢，最好从零位起调至切割稳定，电流表指针不再激烈晃动。

When advancing large thickness cutting, frequency tracking shall be properly adjusted slow, you'd better adjust it to stable cutting from zero position and ammeter pointer no longer shakes sharply.
