compressed gas stops supply in 15 seconds. When it is at 4-Step point, press down the switch and loosen it, and
cutting starts after arc striking automatically. Press the switch again or press it till the arc is off, then there is no
voltage output, cutting ends, and compressed gas stops supply in 15 seconds.

Method for gouging surface adjustment
According to the exact requirements, the gouging surface parameter can be adjusted:
1)
Increase the torch move speed can reduce the gouging width and depth
2)
Reduce the torch move speed can increase the gouging width and depth
3)
Increase the basic distance can increase the gouging width and reduce the depth
4)
Reduce the basic distance can reduce the gouging width and increase the depth
5)
Increase the angleαcan reduce the gouging width and increase the depth
6)
Reduce the angleαcan increase the gouging width and reduce the depth
7)
Increase the current can increase the gouging width and depth
8)
Reduce the current can reduce the gouging width and depth
9)
ncrease the nozzle size can reduce the gouging depth and increase the width
