INTRODUCTION
2T.01 Scope of Manual
This manual contains descriptions, operating
instructions and maintenance procedures for the
1Torch Models SL100SV/Manual and SL100SV/
Mechanized Plasma Cutting Torches. Service of
this equipment is restricted to properly trained
personnel; unqualied personnel are strictly cau-
tioned against attempting repairs or adjustments
not covered in this manual, at the risk of voiding
the Warranty.
Read this manual thoroughly. A complete under-
standing of the characteristics and capabilities of
this equipment will assure the dependable opera-
tion for which it was designed.
2T.02 General Description
Plasma torches are similar in design to the auto-
motive 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 ows through the small orice 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 second-
ary gas. The air ow 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 Supply
used.
