1. A plasma torch head comprising:

  • at least one fluid passage, an electrode, a nozzle, a current conductor and a bearing surface on a bearing side, said torch head having on said bearing side a cylinder wall with an outer surface and an annular surface, said outer surface having nVer similar radial indentations and nVor similar radial projections provided peripherally thereon where nVer, nVor are >

    0 and nVer+nVor=n≧

    5, a quantity n combined radial indentations and radial projections, and at least five angles at the center α

    , β

    , γ

    , δ

    , and ε

    ;

    where n=5, the sum of two adjacent angles at the center among α and

    β

    , β and

    γ

    , γ and

    δ

    , δ and

    ε

    , and ε and

    α

    , by which at least one said projection and one said indentation are offset from one another, is not ≧

    180°

    , and said angles at the center α

    , β

    , γ

    , δ

    , and ε

    are different in size; and

    where n>

    5;

    where the n>

    5 angles at the center α

    , β

    , γ

    , δ

    , and ε

    are different in size, the sum of two adjacent angles at the center among α and

    β

    , β and

    γ

    , γ and

    δ

    , δ and

    ε

    , and ε and

    α

    , by which at least one said projection and one said indentation are offset from one another is not ≧

    180°

    ; and

    where at least two of the n>

    5 angles at the center among α

    , β

    , γ

    , δ

    , and ε

    are equal in size, the sum of the respective angles at the center among α

    , β

    , γ

    , δ and

    ε

    , occurring twice and the adjacent angles at the center on either side thereof among α and

    γ

    , β and

    δ

    , γ and

    ε

    , δ and

    α

    , and ε and

    β

    is <

    180°

    .
