2T.01 Scope of Manual
This manual contains descriptions, operating instructions
and maintenance procedures for the 1Torch Models SL100/
Manual and SL100/Mechanized Plasma Cutting Torches.
Service of this equipment is restricted to properly trained
personnel; unqualified personnel are strictly cautioned
against attempting repairs or adjustments not covered in
this manual, at the risk of voiding the Warranty.
Read this manual thoroughly. A complete understanding
of the characteristics and capabilities of this equipment will
assure the dependable operation for which it was designed.
2T.02 General Description
Plasma torches are similar in design to the automotive spark
plug. They consist of negative and positive sections sepa-
rated 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 ion-
ized 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 "2T.05 Introduction to
Plasma" on page 2T-2, for a more detailed
description of plasma torch operation.
Refer to the Appendix Pages for additional
specifications as related to the Power Sup-
ply used.
