Parker Ionics “Pulse Power” corona charging method supplies excellent transfer efficiencies, superior powder penetration and a quality finish with no gun adjustment needed. Pulse Power improves overall gun performance and transfer Efficiencies by pulsing the charge to the external electrode Several times a second. The continuous pulsing prevents a build-up of free ions on the electrode, resulting in a smoother transfer of powder. The rapid on-off-on-off of the charge allows the powder to be carried by momentum into recessed or Faraday Cage areas. Also, reducing free ions minimizes back-ionization for an even smoother, higher quality finish.
