Patent number: 10721812Abstract: A consumable set for a plasma arc torch is provided. The consumable set comprises a consumable tip including a plurality of consumable components, at least one of which includes an asymmetric feature asymmetrically disposed in the consumable tip relative to a longitudinal axis. The consumable set also includes a mounting element for coupling the consumable tip to a torch body. The mounting element is configured to axially secure the consumable tip relative to the torch body while permitting independent rotation of the consumable tip relative to the longitudinal axis during assembly. The mounting element is also configured to both axially and radially fix the consumable tip with respect to the torch body such that the asymmetric feature is locked at the specific radial orientation relative to the longitudinal axis after securement.Type: GrantFiled: August 24, 2017Date of Patent: July 21, 2020Assignee: Hypertherm, Inc.Inventors: Peter Twarog, Clifford G. Darrow, E. Michael Shipulski, Martin Higgens

Patent number: 10542614Abstract: 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.Type: GrantFiled: September 27, 2013Date of Patent: January 21, 2020Assignee: Hypertherm, Inc.Inventors: Zheng Duan, Yu Zhang, Peter Twarog, Sung Je Kim, Michael F.

Patent number: 9781818Abstract: A consumable set is provided that is usable in a plasma arc torch to direct a plasma arc to a processing surface of a workpiece. The consumable set comprises a nozzle and an alignment surface. The nozzle includes: 1) a nozzle body defining a longitudinal axis extending therethrough, and 2) a nozzle exit orifice disposed in the nozzle body for constricting the plasma arc. The nozzle exit orifice defines an exit orifice axis oriented at a non-zero bevel angle relative to the longitudinal axis. The alignment surface is generally parallel to the exit orifice axis and dimensioned to align the exit orifice such that the plasma arc impinges orthogonally on the processing surface of the workpiece. The alignment surface is configured to lay at least substantially flush against a guiding surface angled relative to the processing surface of the workpiece.Type: GrantFiled: November 14, 2016Date of Patent: October 3, 2017Assignee: Hypertherm, Inc.Inventors: Peter Twarog, Clifford G.
