[0026] In the initial state, the top plate 16 is located at the upper position, the cylinder 19 is in a stopped working state, and the baffle 14 is located at the front position.

[0027] Personnel rotate the handwheel 11 to indirectly move the slider 13 and the baffle 14 back and forth, and personnel calculate the distance between the baffle 14 and the cutting position of the plasma cutter 35 to adjust the position of the baffle 14.
