Universal
PTA torch with accessory nozzles for outside and
inside surfacing |
The PP-6-03 PTA torch is designed for PTA-process
mainly under the conditions of heavy-duty industrial
applications. |
|
It consists of two parts - plasma torch and
holder with horizontal disposed coupling.
The plasma torch is attached to the holder by supply
tubes and fixed by four screws. This original attachment
unit permits to connect or disconnect the plasma torch
for service very quickly and take aside from the hot
surfacing zone all its service lines.
|
The plasma torch complete set includes four couples of
plasma and focusing nozzles of different dimensions.
Indeed, there are four 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.
