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.
