INTRODUCTION
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 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" on page 2T-2, for a more detailed descrip-
tion of plasma torch operation.
Refer to the Appendix Pages for additional specifi-
cations as related to the Power Supply used.
