2.04 Options And Accessories
These items can be used to customize a standard system
for a particular application or to further enhance perfor-
mance (refer to Section 6 for ordering information).
• Spare Parts Kits - Kits contain replacement front-
end torch parts. Spare parts kits are available for
standoff cutting, drag cutting, or gouging.
• Circle Cutting Guide - This device provides precise
cutting capability with a hand torch. The guide fits
both the 70° and 90° hand torches. The kits include
roller guides and pivots that attach to the torch.
2.05 Introduction to Plasma
A. Plasma Gas Flow
Plasma is defined as a gas which has been heated to
an extremely high temperature and ionized so that it
becomes electrically conductive. The plasma arc cut-
ting and gouging process use this plasma to transfer
an electrical arc to the workpiece. The metal to be cut
or removed is melted by the heat of the arc and then
blown away.
While the goal of plasma arc cutting is separation of
the material, plasma arc gouging is used to remove
metals to a controlled depth and width.
In a Thermal Arc Plasma Cutting Torch a cool gas such
as air or nitrogen (N2) enters Zone B (refer to Figure
2-4), where a pilot arc between the electrode and the
