2.02 General Description

NOTE

Refer to Section 2.05, Introduction To Plasma, for
a more detailed description on plasma theory.

The Liquid Cooled Maximizer 300 Torch is a liquid cooled
torch that provides cutting capacity of up to 2 inches (50.8
mm), or 1 inch (25.4 mm) for production speed cutting,
at 300 amperes.

Plasma torches are similar in design to the common au-
tomotive spark plug. They consist of negative and posi-
tive sections which are separated by a center insulator.
Inside the torch, the pilot arc is initiated in the gap be-
tween 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. The torch connects to fittings inside the Arc
Starter Box.
