Figure 6-2 compressed air control diagram
Method 2:
Method 2 is simple and economic, as shown in the figure 6-3 below. Auxiliary air only uses one valve. Gas
source must be replaced manually in the process of metal cutting and nonmetal cutting. Gas pipeline must connect
to compressed air manually for non-metal cutting. And gas pipeline must connect to oxygen pipeline manually for
metal cutting,
When switching to automatic mode to cut metal, O2 gas is controlled by LFS controller. O2 is closed when
the laser head rising up. The O2 will blow when the laser head move down to the focus position. When punching
hole, the O2 with low pressure is opened. The O2 with high pressure is opened when cutting.
While switching to manual mode to cut non-metal, CON0-PIN10 (OUT2) output low level all the time, the
relay is always closed. So the compressed air is always blowing.
Switching from manual mode to automatic mode, CON0-PIN10 (OUT2) output high level, the relay is
opened.
