Sistema PTA-P

As differentials, the equipment brings together, in a single cabinet, the power units for the main arc and the pilot arc, the high frequency igniter for the pilot arc, the electronic valves for controlling the flow of plasma gas and carrier gas, the control electronics for the powder feeder, the system microprocessor control unit and the configuration interface (human-machine interface (HMI)).

The control software enables, through the HMI, the electronic regulation of all process parameters, including the pilot arc current, the flow rates of the plasma and powder gases and the flow rate. powder mass flow rate. Together with the possibility of customization, this flexibility allows both the industrial and research and development sectors a wide range of process optimization for each specific application.

In its version for automated application, the DIGIPLUS A7 PTA can, also through the HMI, control the Tartílopes robotic manipulators, included in the SPS line, as well as other positioning and movement systems (for example, rotating tables).

The ADP – Powder Feeder – provides high performance in feeding powdered metallic consumables. It can be used with powders compatible with the standards used in the PTA-P process with regard to shape and size (granulometry).

Using the mechanical principle of conveyor belts, a dosing drum transfers the material contained in the silo to the pneumatic transport hose. The feeding rate of welding consumables can be regulated both by rotating the drum and by adjusting the height between the drum and the silo discharge channel (GAP).

The ADP – Powder Feeder –  provides continuous feeding with good regularity, providing high quality welds. It is ideal for industrial applications, being robust and highly durable equipment.

PTA-P welding torch

Manual version

Machined version

The PTA-P torch has a compact design and is distinguished by the presence of only one water cooling circuit, reducing the number of accessories for coating or joining operations, contributing to better mobility of the system as a whole. Furthermore, special attention was paid to the assembly design of the parts, making changing consumables simpler and faster.

In one of its versions (upon request), it allows welding in out-of-plane positions in a consistent manner, without the accumulation of filler material (metallic powder) inside and with regularity in the injection jets of material to the melting pool, maintaining lower carrier gas values compared to other models on the market.
