PM-300M with two powder feeders
PM-300M system is designed
for semi-automatic and manual PTA surfacing of different parts to protect them against wear, corrosion etc.
The PTA torch operates only with plasma transferred
arc which burns between a non-melting tungsten electrode
and work piece.
As an additive material the fine-grained powder of wear-resistant,
corrosion-resistant and other alloys on Fe, Ni and Co base is used.
Pure argon (99,995% Ar) is used as working gas.
In some cases for improvement shielding of welding pool and prevention of possible pores formation in a deposited metal
it is possible to use as a shielding gas a mixture of an argon with a hydrogen (95%Ar + 5%H2).
