Ensure the centering between electrode and nozzle precisely, so that the
compression of the plasma arc is not damaged, the concentration of flame and
cutting capacity can be guaranteed.
Enough power to ensure the fluidity of molten metal, as well as increase the
stability of the cutting speed and operation. This makes it possible to adopt large
air flux to enlarge the air blow force, and beneficial for eliminating burr.
Adjust suitable air flux and cutting speed. If the air flux is too small, the blow
force is not enough, while if too big, the plasma arc will be shorten, the incision will
be “V” shape, the drag enlarge. The burr can be formed under both conditions.
When cutting speed is too slow, the incision is large and rough, the bottom is easy
to be over-heated, while the cutting speed is fast, the drag is enlarged, this is not
beneficial for eliminatingburr.
So under certain circumstance, there exists a proper selection range for air flux and
cutting speed.
12) Diminish the cutting surface slanting and rounding problem
The incision surface is a little slant and the upper side is a little round during
cutting with air plasma. Though the slanting range is acceptable during the cutting
process, in order to improve the cutting quality, people begins to pay attention to this
problem. Usually slowing down the cutting speed properly can avoid the slanting, but
this may enlarge the effect zone and incision width, as well as decrease the production
capacity, so this measurement is not wildly used. Recently, people can avoid the
slanting by improving the nozzle structure, this is called super cutting method. By
adopting multi-hole nozzle during the cutting process, the air current from the small
hole is parallel with that from the main hole, this can avoid the dispersing of the
plasma flame on metal top, and then a parallel incision, square upper side and no
metal slag seam on the lower side is obtained.
Troubleshooting & repair
1
、
If there is trouble caused by high voltage in the machine, a professional electrician or
serviceman of our company is required to repair it.
2
、
Please check following first when there is trouble.
1)
The three-phase power should be 380±40VAC
，
check if it misses phase or
voltage fluctuation exceeds its required range of power supply
；
2)
Check if the supply abnormity indicator lamp is ON. If it is ON, check if the
three-phase power switch of distribution box is damaged, and if the fuse and the
machine power wire are well equipped. Otherwise it will cause phase missing or bad
contact, which makes the machine work abnormally
；
3)
Check if the torch switch and its wire are damaged or short-circuit, and if the nozzle
and electrode aredamaged
；
4)
If the control plug is connected mistakenly after user exchanging a different torch
from another manufacturer,please proceed thechecking as per “torch connection”
mentioned in instructionmanual.
5)
Check if the cutting ground wire is well connected
