PP-7

PP-7 compact PTA torch is intended for outside plasma transferred arc surfacing (PTA-process) of different small parts or in hard-to-reach places by Fe-, Ni- and Co-based alloys.

Pure argon (99.995% Ar) is used as a working gas.



Features

• Vertical design
• Maximum transferred arc current: 120A (100% duty cycle)
• Available replaceable plasma nozzles with different orifice diameter. They are used in combinations (plasma nozzle/focusing nozzle): 2.0/5.0 and 2.5/5.0 mm
• Fully dismountable design
• Powder feeding system – internal
• Real powder losses: <5%
• Direct cooling of all loaded parts
