The distinction between the intensity and weakness of the cutting air flow of the CNC flame cutter

In CNC flame cutting operations, if the penetration capacity of the cutting air flow is too strong, the possible reason is: before cutting the cutting oxygen pressure is too high, in the cutting of the cutting oxygen valve open too large.
The main characteristics of excessive penetration of the cutting air flow are as follows:
1. The preheating flame ejected from the cut mouth spreads evenly around the workpiece plane, with only a small narrow strip of flame leaking into the incision at the forming incision.
2. The geometric shape deformation of the semi-circular notch caused by the contact between the cutting air flow and the workpiece.
3. The lower part of the incision is blown off by the cut air splash slag discharge strongly.
4. Hear the strong cut sound of the "stoa" .
5. Cut the mouth slightly sticky slag, cutting air flow immediately deformed, cutting surface texture rough, easy to appear concave or small and large horn-shaped incision.
Here's how:
The small cutting oxygen valve should be closed in time, or the output pressure of the small pressure reducer, if the cutting air flow deformation is found, the valve should be shut down immediately, to be trimmed after cutting the mouth, and then re-ignited the torch to continue cutting.  If the penetration capacity of the cutting air flow is too weak, the possible reason is: before cutting the cutting oxygen pressure is too low, in the cutting of the cutting oxygen valve opentoo small, or cut in the cut cut oxygen hole is blocked by splashes.
The main characteristics of the weak penetration of the cutting air flow are as follows:
1. The preheating flame ejected from the cut mouth spreads evenly around the workpiece plane, only a small narrow bar of flame is raised upward at the forming incision, and in severe cases, it is turned upward from the incision, and the splash slag blown off by the cut air in the lower part of the cut cannot hear the sound of "squirting" sound.
2. The ability to cut the workpiece is insufficient, which will cause the horn-shaped incision of the large and small ones.
Here's how:
1. The penetration of the cutting air flow should be increased immediately, the output pressure of the large cutting oxygen valve can be opened, or the output pressure of the large decompressor can be adjusted.
2. If the cut mouth has cutting splash blockage, should immediately stop cutting, wait to repair the cut mouth after the re-ignition cut.  In the cutting before the cutting oxygen pressure is adjusted properly, in the cutting of the cutting oxygen valve open degree appropriate, you can obtain the appropriate cutting oxygen penetration. Proper cutting penetration has the following characteristics:
The preheating flame ejected from the cut mouth spreads evenly around the workpiece plane, only in the incision with a small narrow strip of flame leaking into the incision; the geometry of the semi-circular notch produced by the cutting air flow in contact with the workpiece is good; the lower part of the cut air is blown off the splash; when the slag is discharged, the cutting sound is made; the cut is fine, The cut is wide and narrow evenly, the verticality is good, and there is less slag or no hanging slag.
