Patent number: 7659488Abstract: A plasma arc torch that includes a torch body having a nozzle mounted relative to a composite electrode in the body to define a plasma chamber. The torch body includes a plasma flow path for directing a plasma gas to the plasma chamber in which a plasma arc is formed. The nozzle includes a hollow, body portion and a substantially solid, head portion defining an exit orifice. The composite electrode can be made of a metallic material (e.g., silver) with high thermal conductivity in the forward portion electrode body adjacent the emitting surface, and the aft portion of the electrode body is made of a second low cost, metallic material with good thermal and electrical conductivity. This composite electrode configuration produces an electrode with reduced electrode wear or pitting comparable to a silver electrode, for a price comparable to that of a copper electrode.Type: GrantFiled: July 28, 2006Date of Patent: February 9, 2010Assignee: Hypertherm, Inc.Inventors: David J.

Patent number: 6614001Abstract: An output structure for material processing apparatus facilitates field replacement of consumable components, while maintaining important alignments. Contoured surfaces within the output structure mate with corresponding contoured surfaces on the consumable components, thereby facilitating alignment of the consumable components with an axis of the output structure. Material processing apparatus employing such surfaces include lasers and plasma arc torches and, with proper alignment, apparatus performance is improved. Typical consumable components include electrodes, swirl rings, nozzles, and shields. The consumable components can be axially translatable with respect to each other, thereby promoting contact starting of a plasma arc torch. An installation tool for consumable components also serves to align the components with an axis of the output structure.Type: GrantFiled: May 21, 2002Date of Patent: September 2, 2003Assignee: Hypertherm, Inc.Inventors: Charles M.

Patent number: 5994663Abstract: Disclosed is a novel method and structure for contact starting a plasma arc torch. A translatable, electrically conductive component such as a nozzle or swirl ring is biased into contact with an electrode by a compliant spring element. A pilot arc is formed by first passing current through the electrode/component interface. Thereafter, the component is translated under the influence of gas pressure in a plasma chamber formed between the electrode and component, compressing the compliant element and initiating the pilot arc. The spring element may be a separate element or may be maintained integrally with the nozzle, swirl ring, or a retaining cap, facilitating removal and replacement of the spring element with consumable components of the torch.Type: GrantFiled: October 8, 1996Date of Patent: November 30, 1999Assignee: Hypertherm, Inc.Inventor: Zhipeng Lu
