PTA - Technology

Basic PTA components

Our company offers complete system solutions in the field of PTA equipment technology. PTA facilities include the following basic components:

  • Power supply unit
  • Plasma torch
  • Powder-feed system
  • Welding torch system
 

 

Powder-feed system

Gas-driven powder-feed system with tacho-regulated motor, high metering accuracy, powder feed rate: 2 to 120 g/min with interchangeable feed discs, single or double powder outlet

 

Plasma torch PT 300

Vertical machine torch with hose package 5 m in length (optional: 10 m) for joining or weld surfacing by the plasma-powder process; maximal load: 250 A / 100 % ED(1); designed for accepting special plasma anodes; suited for operation in all positions; maximal powder feed rate: 2 to 80 g/min, depending on the installed plasma anode

(1) with the use of an active cooling system

 

Cooling system

Compact air-cooled water-recooling unit available in a range of different cooling-capacity ratings; individual or built-in unit for use with power-supply units of series 250; external water-level gauge; stainless-steel pipe-coil evaporator; temperature control by means of a digital thermostat +/- 1.0 K; TÜV-tested high-pressure relief valve in coolant circulation system; tank drainage through the water-level gauge; environmentally compatible coolant R 407c; protective system: IP 44; for operation at an ambient temperature up to 42 °C (higher temperature ranges available on request)

 

Plasma current source PlasmaArc 300A / 450A

Upright plasma-welding power supply unit with electronic gas-control system; BUS interface; connections for remote controller / robot / manipulation systems; programmable controller with high memory capacity (16 kB) including capability of recording 99 sets of welding parameters (> 30 welding parameters per set); control unit switchable for operation with powder or wire; battery module for no-voltage backing of the welding parameters; all gas hoses 5 m in length; non-confusable water connections; welding parameter software for automatic-routine and manual function.
