Read this manual thoroughly. A complete understanding
of the characteristics and capabilities of this equipment

2.02 General Description
Plasma torches are similar in design to the automotive
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 elec-
trode 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
Refer to Section 2.05, Introduction To Plasma, for a

tion.

cations as related to the Power Supply used.
