General Description
Plasma torches are similar in design to the auto-
motive spark plug. They consist of negative and
positive sections 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 sec-
ondary gas. The air flow is divided inside the torch
head. Single - gas operation provides a smaller
sized torch and inexpensive operation.
NOTE!
Refer to Section "2T.05 Introduction to Plasma"
on page 2T-2, for a more detailed description of
plasma torch operation.
Refer to the Appendix Pages for additional specifi-
cations as related to the Power Supply used.
