Automated Plasma Interface 467
Material Thickness
The desired material thickness may be selected.
The following are the Cut Process parameters within the database which are used to configure the
power supply. Appropriate parameter information is transmitted to the power supply.
1) Material Type – Mild Steel, Stainless Steel, Aluminum, or Mild Steel (Cold Rolled).
2) Thickness
3) Set Current
4) Pierce Delay
5) Set Preflow Pressure
6) Set Plasma Gas type
7) Set Plasma Pressure
8) Set Shield Gas Type
9) Set Shield Pressure
10) Set Process (Cut/Mark)
The following items are stored in the Cut Chart Data file and will be automatically updated on the
control.
Cut Speed
Specifies the speed for the selected process variables.
Kerf
Specifies the amount of kerf (cutter compensation) that will be applied to the current part program.
Preflow Time
Specifies the amount of time the Preflow gases are on.
Purge Time
Specifies the time delay from torch ignition until motion is enabled.
Pierce Time
Specifies the time delay from when torch completes lowering until motion is initiated at Creep Speed.
Used to allow the plasma torch to completely pierce the material before moving.
Creep Time
Specifies the amount of time after piercing the part that the torch travels at Creep Speed. Creep
Speed is determined by a setup parameter at the Speeds setup screen and is a percentage of the
programmed cut speed. After the Creep Time is completed, the control accelerates to full cut speed.
Database Features
Save Process
Pressing the Save Process soft key allows the user to save the current process settings to the Hard
drive creating a custom user database based on the eight process variables selected.
