PM-150M PTA system
Remote control unit
PP-25
Plasma torch
|
The new development of PM-150M system is designed
for manual PTA surfacing of different parts to hardface
and protect them against wear corrosion, cavitation
etc.
The plasma torch operates only with plasma transferred
arc which burns between a non-melting tungsten electrode
and work piece.
It is possible to deposit Fe-, Ni-, and Co- based
alloys on working and supporting surfaces.
Pure argon is used as a working gas. There is an
optional ability to use a gas mix (argon + 5% hydrogen)
for the shielding improvement. The operating conditions
of the system (argon or gas mix usage) assigns by
operator with the aid of the panel microcontroller.
The control system of new PM-150M model designed
on a basis of the panel controller SMH-2010C

Controller
SMH-2010C
This engineering solution expands technological
abilities of the PTA system, allows flexibility of
resetting and semi-automatic modes of operation with
fitted peripheral equipment (rotator, turn-table,
plasma torch positioing gear etc.)
It makes PM-150M more universal than just the
manual PTA system.
