Plasma cutting, Poltava region.

Plasma cutting is a type of plasma processing of materials, in which a plasma jet is used as a cutting tool instead of a cutter.
Advantages of plasma cutting:

any metals are processed — black, non-ferrous, refractory alloys, etc.(//tractor-service.com)
the cutting speed of small and medium thicknesses is several times higher than the speed of gas flame cutting.
small and local heating of the cut workpiece, which excludes its thermal deformation
high purity and quality of the cut surface
safety of the process (no need for cylinders with compressed oxygen, flammable gas, etc.)
a complex figured cutout is possible
