PP-9L PTA torch is designed for plasma transferred arc surfacing (the PTA-process) in hard-to-reach places of different parts (seal faces inside of body of small-sized stop valve and etc.).
PTA torch has vertical version in which all nipples for connection the feeding communications on the upper end are placed.

To avoid an electrical contact between PTA torch and hard-faced part its shielding nozzle is covered by ceramic.

The PTA torch complete set includes two couples of plasma and focusing nozzles of different dimensions. Indeed, there are two torches in one. Necessary combination of nozzles is selected according to required power and concentration of plasma arc (see Table I.).

It is possible to deposit Fe-, Ni- and Co- based alloys on working faces of different parts to protect them against wear, corrosion etc. Pure argon (99,995% Ar) is used as a working gas.
