Abstract
A plasma cutting system is provided. The system includes a power source configured to generate a plasma arc, and a plasma arc torch connected to the power source for delivering the plasma arc to a workpiece. The plasma arc torch defines a multi-function fluid flow path for sustaining the plasma arc and cooling the plasma arc torch such that the plasma cutting system has a power-to-gas flow ratio of at least 2 kilowatts per cubic feet per minute (KW/cfm). The power-to-gas flow ratio comprises a ratio of power of the generated plasma arc to a total gas flow supplied to the plasma arc torch.
