INTRODUCTION
2T.01 Scope of Manual
This manual contains descriptions, operating instruc-
tions and maintenance procedures for the 1Torch Mod-
els SL60QD™ hand torches and SL100SV Automated
Plasma Cutting Torches. Service of this equipment is
restricted to properly trained personnel; unqualified
personnel are strictly cautioned against attempting re-
pairs 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 sec-
tions separated 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 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 "2T.05 Introduction to
Plasma", 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.
