Plasma torches with water-stabilized arc (Gerdien arc) are utilized in plasma processing for specific applications. In water-stabilized torches an oxygen-hydrogen plasma jet is produced. The torches are characterized by very low mass flow rates and high power. Plasma enthalpy is thus several times higher than enthalpy of plasmas generated in gas-stabilized torches. High enthalpy is accompanied by very low plasma density. Also other plasma parameters substantially differ from the ones in gas torches. New type of plasma torch with combined stabilization of an electric arc by water vortex and gas flow was investigated. This hybrid water/gas stabilization offers possibility of adjustment of plasma jet parameters in a wide range from high enthalpy, low density plasmas typical for liquid stabilized torches to lower enthalpy, higher density plasmas generated in gas stabilized torches.

Vodou stabilizované plazmatrony jsou používány pro speciální plazmové technologie. Plazmatrony jsou charakterizovány velmi nízkým průtokem plazmatu a vysokým výkonem. Hybridní plazmatron kombinuje princip vodou stabilizovaného a plynového plazmatronu. Jsou popsány vlastnosti a aplikace obou typů plazmatronu.
