Set-up and functional principle Plasma Jet

The system consists of three units:

1. Supply unit

  • electrical mains supply
  • Process gas and cooling gas connection
  • High-voltage generator
  • Current measurement block
  • Gas control block
  • Front panel with controls

2. Gas and electricity supply in flexible tube

3. Plasma generators: the central electrode, outer electrode and insulator form a discharge zone.

  • The high-voltage generator converts the mains voltage to high voltage (up to 10 kV), which is necessary for the formation of the electric discharge.
  • The supply voltage and the process gas are supplied into the discharge zone by the flexible tube.
  • The air flow carries the resulting active species in the electric arc (i +, e-, r*) from the discharge zone (Plasma Jet process).
  • The flow of the active gas is focused on the workpiece to be treated, by a special nozzle shape .

Set-up and functional principle, Gliding Arc

The system consists of three units:

1. Supply unit

  • electrical mains supply
  • High-voltage generator
  • Control block (micro-controller controlled)
  • Front panel with controls
  • Air supply

2. Power and air supply lines in a flexible tube

3. Plasma generators:

Two electrodes form a discharge zone.

  • The high-voltage generator generates a voltage of up to 10 kV, which is necessary for the generation of the electric discharge.
  • The supply voltage is supplied through the flexible supply tube.
  • The air flow guides the electric arc from the electrode region. (Gliding Arc process)
  • The electric arc comes directly in contact with the surface.

Danger! High Voltage! Do not touch the electric arc or electrodes - Danger to life!
