Patent number: 7582844Abstract: Devices and methods are provided that control gas flow to a plasma arc torch local to a torch handle. Generally, a plasma arc torch is provided that comprises a gas control device operable with a torch lead and a torch head, and an activation member operable with the gas control device. Accordingly, the activation member activates the gas control device such that gas flow is supplied from the torch lead to the torch head, and the activation member deactivates the gas control device such that the gas flow is terminated. Further, the activation member may comprise a trigger system, a button, or a safety member, among others. Moreover, the gas control device may comprise a gas control valve or a switch that activates a gas control device disposed within a power supply, among others.Type: GrantFiled: November 24, 2003Date of Patent: September 1, 2009Assignee: Thermal Dynamics CorporationInventors: Kevin D. Horner-Richardson, Shiyu Chen, Roger W. Hewett, Joseph P. Jones, Kevin J. Kinderson, Darrin H. MacKenzie, Fred Rogers

Patent number: 7429715Abstract: A modular plasma arc torch is provided that comprises a torch head and a torch lead, and a quick disconnect that is operatively engaged between the torch head and the torch lead. Accordingly, the torch head and torch lead may be quickly assembled and disassembled through the use of the quick disconnect. Further, the modular plasma arc torch also comprises a gas control device disposed within the plasma arc torch, which is operatively engaged between the torch head and the torch lead through the use of the quick disconnect according to the present invention. In addition, the quick disconnect may be used to connect a wide range of torch components within a plasma arc torch, thereby providing a reconfigurable plasma arc torch. Moreover, the quick disconnect according to the present invention conducts both gas and electric power from a power supply to the torch head for operation of the plasma arc torch.Type: GrantFiled: February 26, 2002Date of Patent: September 30, 2008Assignee: Thermal Dynamics CorporationInventors: Darrin H. MacKenzie, Shiyu Chen, Roger W. Hewett, Kevin D. Horner-Richardson, Joseph P. Jones

Patent number: 7202440Abstract: A dual mode plasma arc torch is provided that preferably comprises a start cartridge disposed between an electrode and a tip. In one form, the start cartridge comprises an initiator that is in electrical contact with the electrode and that is resiliently biased into contact with the tip, such that when the plasma arc torch is in a contact start mode, the initiator is movable against the resilient bias to separate from the tip and establish a pilot arc between the initiator and the tip. Further, when the plasma arc torch is in a high frequency start mode, the start cartridge spaces the tip from the electrode such that a pilot arc is established between the electrode and the tip. In other forms, a contact start torch is provided that is operable under high frequency, and conversely, a high frequency start torch is provided that is operable under low voltage.Type: GrantFiled: July 18, 2005Date of Patent: April 10, 2007Assignee: Thermal Dynamics CorporationInventors: Roger W. Hewett, Kevin D. Horner-Richardson, Joseph P. Jones, Shiyu Chen, Fred A. Rogers

Patent number: 7145099Abstract: A tip gas distributor is provided that preferably comprises a plurality of swirl holes and a plurality of secondary gas holes, wherein the swirl holes direct a plasma gas to generate a plasma stream, and the secondary gas holes direct a secondary gas to stabilize the plasma stream. Additionally, a tip gas distributor is provided that comprises swirl passages and secondary gas passages formed between the tip gas distributor and an adjacent component to generate and stabilize the plasma stream. Further, methods of generating and stabilizing the plasma stream are provided through the use of the swirl holes and passages, along with the secondary gas holes and passages.Type: GrantFiled: March 16, 2004Date of Patent: December 5, 2006Assignee: Thermal Dynamics CorporationInventors: Kevin D. Homer-Richardson, Joseph P. Jones, Roger W. Hewett, Shiyu Chen

Patent number: 7022936Abstract: A trigger system for operating a plasma arc torch is provided that comprises a selector that operates between at least a first operating position and a second operating position, wherein the first operating position operates the plasma arc torch in a first mode to deliver gas to the plasma arc torch, and the second operating position operates the plasma arc torch in a second mode to deliver the gas and electric power to the plasma arc torch. Further, the selector comprises a neutral position that selects a neutral mode in which delivery of gas and electric power to the plasma arc torch is inhibited. The selector is preferably disposed within a housing of the plasma arc torch and is slidably operable between the first operating position, the second operating position, and the neutral position.Type: GrantFiled: September 30, 2003Date of Patent: April 4, 2006Assignee: Thermal Dynamics CorporationInventors: Joseph P. Jones, Kevin D. Horner-Richardson, Kevin J. Kinnerson

Patent number: 6903301Abstract: A contact start plasma arc torch is provided that comprises an electrode, a tip, and an initiator that is resiliently biased into contact with the tip, the initiator being movable against the resilient bias to separate from the tip and establish a pilot arc between the initiator and the tip. The initiator is disposed within a start cartridge, which preferably comprises a coil spring that biases the initiator into contact with the tip. The plasma arc torch further comprises a plurality of head vent holes to vent gas from within the start cartridge during operation of the torch. Additionally, the tip defines a plurality of swirl holes and secondary gas holes to generate and control a plasma stream that is subsequently blown from a central exit orifice in the tip.Type: GrantFiled: February 26, 2002Date of Patent: June 7, 2005Assignee: Thermal Dynamics CorporationInventors: Joseph P.
