Plasma torch with LCD display with settings adjustment and fault diagnosis
First Claim
1. A portable plasma arc cutting system comprising:
- a power supply;
a plasma torch attachable to the power supply and generating a plasma arc for cutting a workpiece;
a gas valve disposed in the portable plasma arc cutting system or the plasma torch, the gas valve establishing a gas flow rate or a gas pressure in the plasma torch;
a controller within the portable plasma arc cutting system and in communication with the power supply, the controller capable of automatically manipulating the gas valve to establish the gas flow rate or the gas pressure based upon a predetermined operating condition; and
a user activated switch in communication with the controller, the switch havinga first setting which causes the controller to automatically establish the gas flow rate or the gas pressure based upon the predetermined operating condition, anda second setting which causes the controller to establish one of a user-determined gas flow rate or a user-determined gas pressure by increasing or decreasing the gas flow rate or the gas pressure by manipulating the gas valve based on information that has been input into the plasma arc cutting system by a user.

Abstract
A portable plasma cutting system includes a power supply and a torch attachable to the power supply. The torch generates a plasma arc for cutting a workpiece. A gas valve is disposed in the system or the torch. The gas valve establishes a gas flow rate or a gas pressure in the torch. A controller is within the system and in communication with the power supply. The controller is capable of automatically manipulating the gas valve to establish the gas flow rate or pressure based upon a predetermined operating condition. A user activated switch is in communication with the controller. The switch has a first setting which causes the controller to automatically establish the gas flow rate or pressure based upon the predetermined operating condition, and a second setting which causes the controller to establish one of a user-determined gas flow rate or a user-determined gas pressure.

22. A plasma arc cutting system comprising:
-
means for supplying power; means for attaching a plasma torch to the means for supplying power and initiating a plasma arc for cutting a work piece; means for establishing a gas flow rate or a gas pressure from a gas source to the plasma torch; means for automatically establishing the gas flow rate or the gas pressure of the gas based upon a predetermined operating condition; means for manually establishing the gas flow rate or the gas pressure of the gas based upon a user-determined gas flow rate or a user-determined gas pressure; and means for switching between automatically establishing the gas flow rate or the gas pressure and manually establishing the gas flow rate or the gas pressure, wherein manually establishing the gas flow rate or the gas pressure comprises manipulating the gas valve based on information that has been input into the plasma arc cutting system by a user.
