Patent number: 8624150Abstract: An apparatus and method for extending a plasma arc torch is disclosed. The apparatus includes a plasma torch adapter for relocating a mounting location of plasma torch consumables with respect to a plasma arc torch. The adapter is configured to be mounted between a plasma arc torch and the plasma torch consumables. The adapter is connectable to a consumable interface of the torch and includes a generally longitudinal body having a first end and a second end. The adapter includes a first connector at the first end of the body that is adapted to mate with the consumable interface. The adapter further includes a second connector at the second end of the body for mating with a set of plasma torch consumables, such that a second mounting location for consumables is established in a spaced relationship relative to the first connector, the mounting location adjacent the second connector.Type: GrantFiled: September 9, 2010Date of Patent: January 7, 2014Assignee: Hypertherm, Inc.Inventors: Richard Joseph Simek, Jonathan Mather, Peter J. Twarog, Stephen Theodore Eickhoff

Publication number: 20130306607Abstract: An improved electrode for use in a plasma arc torch. The electrode includes an electrode body, a cavity in a front face at a first end of the electrode body, and an insert disposed in the cavity. The first end of the electrode body is formed of high purity copper containing at least 99.81% copper. The insert has a first end and a second end and is formed of a high emissivity material. A diameter of the first end of the insert is less than a diameter of a second end of the insert. An electrode is compressed to retain the insert using radial compression. The invention also includes a method for forming the electrode, and a method of operation of an electrode in a plasma torch.Type: ApplicationFiled: May 23, 2012Publication date: November 21, 2013Applicant: Hypertherm, Inc.Inventors: Jonathan P.
