PT-600 Mechanized Plasma Cutting Torch

SECTION 4
OPERATION
4.5 Process Data
4.5.1 Introduction
The following information is a result of many hours of
testing and is a general guide for setting up and
cutting with a PT-600 Mechanized Plasma Arc Torch.
The machine’s control manages gas flow using Smart
Flow II, a proportional valve flow control system.
In most cases these settings will provide a quality cut.
The data contains values for:
cutting aluminum, carbon and stainless steel
arc voltage (standoff)
cutting speed
current (amperes)
gas flow rates for plasma/shield gas combinations
This same data is contained in SDP files. (See your
machine and programming manuals for more
information on SDP files.)
Also included is information on consumable part
numbers for all possible current settings.
NOTICE
Speed, voltage, kerf, and current can be
used any time for a PT-600 torch
application.
Process data was derived using the Smart Flow II, a
programmable gas flow control. This same
information is used in creating Vision CNC process
control (SDP) files. Only gas flow rates are given for
reference when using Smart Flow II. Speed, arc
voltage, kerf, and current (amperes) remain
applicable when cutting with manual gas
regulation systems.
NOTICE
Underwater Cutting Speeds Must Slowed by
10%.
As a general rule, above water cutting speeds
can be applied to underwater cutting by
reducing speeds by 10%. There are two
underwater examples offered for reference in
the following data. (p4-31, p4-91)
