PP-6-04 high-productive PTA torch with internal and external (2-ports) powder feeding systems. It is intended for outside plasma transferred arc surfacing (PTA-process) of composite and ordinary alloys of different parts by Fe-, Ni- and Co-based alloys
Pure argon (99.995% Ar) is used as a working gas.

Plasma transferred arc surfacing of composite alloys with separate feed of tungsten carbides and matrix alloy It has been established that when a self-fluxing nickel-based alloy is used as a matrix, the most stable surfacing process is achieved if tungsten carbides are fed through the axial bore in the focusing nozzle, and the matrix alloy comes through two channels located diametrically opposite to each other at its end.
