Plasma torch with LCD display with settings adjustment and fault diagnosis
First Claim
1. A plasma arc cutting system comprising:
- a power supply;
a plasma torch attachable to the power supply to generate a plasma arc;
an identification device located on a cartridge or a consumable component of the plasma arc cutting system, the identification device containing information establishing necessary operating parameters such that the power supply requires no further user controls when the plasma torch uses automatically established operating parameters;
a reader associated with the plasma torch and capable of reading stored data from the identification devicea controller within the plasma arc cutting system and in communication with the reader and the power supply, the controller capable of automatically establishing operating parameters of the plasma arc cutting system based upon the data stored on the identification device;
a switch means, in communication with the power supply and activatable by a user of the plasma arc cutting system, for toggling between the automatically established operating parameters and a set of user-selected operating parameters; and
a means for storing at least one of the operating parameters last manually entered into the plasma arc cutting system by the user, the means for storing disposed in the power supply and in communication with the controller.

Abstract
A plasma arc cutting system includes a power supply and a plasma torch attachable to the power supply. The plasma torch generates a plasma arc for cutting a workpiece. A reader is associated with the plasma torch. The reader is capable of reading stored data from an identification device located on a cartridge or a consumable component of the plasma arc cutting system. A controller is within the plasma arc cutting system and in communication with the power supply. The controller is capable of automatically establishing operating parameters of the plasma arc cutting system based upon the data stored on the identification device. An override feature allows a user of the plasma arc cutting system to override the automatically established operating parameters of the torch and to input user selected operating parameters.
