2T.02 General Description
Plasma torches are similar in design to the automotive
spark plug. They consist of negative and positive sec-
tions separated by a center insulator. Inside the torch,
the pilot arc starts in the gap between the negatively
charged electrode and the positively charged tip. Once
the pilot arc has ionized the plasma gas, the superheated
column of gas flows through the small orifice in the torch
tip, which is focused on the metal to be cut.
A single torch lead provides gas from a single source to
be used as both the plasma and secondary gas. The
air flow is divided inside the torch head. Single - gas
operation provides a smaller sized torch and inexpen-
sive operation.
NOTE!
Refer to Section "2T.05 Introduction to
Plasma", for a more detailed description of
plasma torch operation.
Refer to the Appendix Pages for additional
specifications as related to the Power Sup-
ply used.
