SECTION 4 TORCH:
OPERATION
4T.01 Torch Parts Selection
Depending on the type of operation to be done deter-
mines the torch parts to be used.
Type of operation:
Drag cutting, standoff cutting or gouging
Torch parts:
Shield Cup, Cutting Tip, Electrode and Starter
Cartridge
NOTE!
Refer to Section 4T.07 and following for additional
information on torch parts.
Change the torch parts for a different operation as
follows:
WARNING
Disconnect primary power at the source before as-
sembling or disassembling torch parts, or torch and
leads assemblies.
NOTE!
The shield cup holds the tip and starter cartridge in
place. Position the torch with the shield cup facing
upward to keep these parts from falling out when
the cup is removed.
1. Unscrew and remove the shield cup assembly
from the torch head.
2. Remove the Electrode by pulling it straight out
of the Torch Head.

is seated on the torch head. If resistance is
felt when installing the cup, check the threads
before proceeding.
4T.02 Cut Quality
NOTE!
Cut quality depends heavily on setup and pa-
rameters such as torch stando, alignment with
the workpiece, cutting speed, gas pressures, and
operator ability.
Cut quality requirements differ depending on applica-
tion. For instance, nitride build - up and bevel angle
may be major factors when the surface will be welded
after cutting. Dross - free cutting is important when
finish cut quality is desired to avoid a secondary clean-
ing operation. The following cut quality characteristics
are illustrated in the following figure:

Cut Quality Characteristics
Cut Surface
The desired or specified condition (smooth or
rough) of the face of the cut.
Nitride Build - Up
Nitride deposits can be left on the surface of the
cut when nitrogen is present in the plasma gas
stream. These buildups may create difficulties
if the material is to be welded after the cutting
process.
Bevel Angle
The angle between the surface of the cut edge
and a plane perpendicular to the surface of the
plate. A perfectly perpendicular cut would result
in a 0° bevel angle.
Top - Edge Rounding
Rounding on the top edge of a cut due to wearing
from the initial contact of the plasma arc on the
workpiece.
