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.

Cutting table
To get excellent cutting quality, reduce the burr as soon as possible, we recommend
user refer to the “cutting table” and choose a suitable cutting parameter. However, according
to different working conditions and cutting materials, user should adjust it as actual
condition.
Cut from edge unless you have to make a piercing.
Choose suitable consumables according to different cutting technology. When change
the consumables, power have to be off, and use the equipped torch use wrench.
The values in the cutting table below is based on “System components” in this operation
manual, it’s a useful reference for some cutting condition.
NOTE: If different torch is used, then the consumables different, the values should be different with the
below table.
