PLASMA  Team Power Source Series 5000 is transistorised and  supervised by a Personal Computer which takes care of the  control and regulation of currents, gas flowrates, time  phases and external units, to be interfaced to a  positioner/manipulator equipment for plasma hardfacing by  Plasma Transferred Arc technique (P.T.A. Process).

The  designed configuration of the power source and the user  oriented software (Dialogue system) will enable real time  setting and regulation of the following parameters:

PILOT ARC Current	DC Power Stage
TRANSFERRED ARC Current	DC Power Stage
PROCESS Times	Internal clock signal
GAS FLOWRATES	Gas Unit
ROTATION SPEED	Plate Rotation
OSCILLATION FREQUENCY	Torch Oscillator
POWDER FLOW RATE	Powder Dispenser
INPUT-OUTPUT SIGNALS	Activation  of  I-O
CONTROLLED  PARAMETERS

Transistor technology supports the instantaneous energy self-adjustment  required by the welding process.
Therefore the  power source does not force its electrical reaction on  the process, but it considers the actual demand of energy  from the arc for powder melting.

PLASMA TEAM  power source has a transistor stage,  electronically controlled, and no inductance coil tied to  the welding process.

The real time  control of this transistor stage secures a specific  energy adjustment of plasma arcs during the different  phases of process; so penetration and shape of the  deposit can be varied in broad limits.

The mind and  core of PTA power source is the computer and the  transistor stage, which controls the energy and heat  input to the hardfacing process; the static as well as  the dynamic behaviour of the power source is determined  by an electronic system controlled by the computer.

All the parameters are easily programmed and displayed on the monitor.  Special routines stored in computer source code select  and elaborate these parameters, transmitting data to the  transistor stage.

The final  result is a welding power source of great precision, the  best possible solution for PTA process.

The personal  computer, which can store thousands of welding programs,  takes the burden of supervisor off the operator shoulders,  thus achieving hardfacing sequences with maximum quality  and repeatability assurance.
