2.02 General Description
NOTE
Refer to Section 2.05, Introduction To Plasma, for a
more detailed description on plasma theory.
The Torch provides cutting capacity of up to 1 inch (25.4
mm) at 100 amperes. In the torch, a single torch lead pro-
vides compressed air or nitrogen (N2) 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 opera-
tion provides a smaller sized torch and inexpensive op-
eration.
Plasma torches are similar in design to the common auto-
motive spark plug. They consist of negative and positive
sections which are separated by a center insulator. Inside
the torch, the pilot arc is initiated 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.
