➢ Parameters of capacitive sensor
Parameters of capacitive sensor have been set before delivery, and users cannot arbitrarily
change.
6.5 Cutting speed
6.5.1 Too fast Cutting
If cutting speed is too fast, it may cause the following consequences.
1) It may be impossible to penetrate, with sparks spraying.
2) Some areas can be penetrated, but some cannot.
3) The entire section is relatively coarse, but it produces no melting stains.
4) Cutting section appears in slanted bars, with melting stains on the lower part.
Figure 5 Too fast Cutting
6.5.2 Too slow cutting speed
1) It will cause super fusion, and the cut surface is relatively coarse.
2) Cutting joint gets widened, and the entire sharp corner is melted.
3) Cutting efficiency is influenced.
6.5.3 Confirm appropriate cutting speed
➢ Determine whether to speed up or down feeding based on cutting sparks (targeted at
cutting with low-pressure oxygen)
1） Spark diffuses from up to down
