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
inexpensive operation.
NOTE!
