Abstract: An electrode for a plasma arc torch includes a generally cylindrical elongated body formed of an electrically conductive material. The elongated body includes a proximal end that connects to a power supply and a distal end that receives an emissive element. The electrode can include a flange that is disposed about a surface relative to the distal end of the elongated body, extends radially from the surface of the elongated body, and is utilized to establish a uniform gas flow distribution of a plasma gas flow about the distal end of the elongated body. The electrode can include a contact element that is in electrical communication with the proximal end of the electrode. The contact element includes seating portion that has an outer width that is greater than the outermost diameter of the electrode body and is configured to position the contact element within the plasma arc torch.
