20080061040, Mar 13, 2008

Filed:

Sep 10, 2007

Appl. No.:

11/852855

Inventors:

Nicholas Sanders - Norwich VT, US
E. Shipulski - Etna NH, US
Mike Hoffa - Lebanon NH, US
Jay Jason - Claremont NH, US

International Classification:

B23K 9/12

US Classification:

219121480, 219130100

Abstract:

A portable plasma arc torch system can be used for processing materials. The system includes a replaceable or rechargeable power source and replaceable or rechargeable gas source. A controller communicates with at least one of the power source or the gas source. A plasma delivery device received via the controller current from the power source and gas from the gas source to generate a plasma arc at an output of the plasma delivery device. The plasma arc can be used to process materials such as metallic workpieces. The plasma arc torch can include a wearable portable assembly which includes the replaceable or rechargeable power and gas source. A plasma delivery device receives current from the power source in the assembly and gas from the gas source in the assembly to generate a plasma arc.

US Classification:

21912149, 2191215, 21912144, 21912152, 295921

Abstract:

A nozzle for a plasma arc cutting torch includes a substantially hollow, elongated body capable of receiving an electrode. The nozzle body defines a longitudinal axis and has a length along the axis from a first end of the nozzle body to a second end of the nozzle body. The nozzle also includes a plasma exit orifice disposed at the first end of the body. The first end of the nozzle body has a width and a ratio of the length of the nozzle body to the width of the nozzle body is greater than about 3.

International Classification:

H05H 1/34

US Classification:

21912149, 2191215, 29525

Abstract:

A nozzle for a plasma arc torch is provided. The nozzle includes a substantially hollow, elongated nozzle body capable of receiving an electrode, the body defining a longitudinal axis, a distal end, and a proximal end. The nozzle also includes a swirl sleeve attachable to an interior surface of the nozzle body, the swirl sleeve configured to impart a swirling motion to a gas introduced to the nozzle. The nozzle additionally includes a nozzle tip connected to the proximal end of the nozzle body, a nozzle shield, and an insulator configured to connect the nozzle tip and the nozzle shield to electrically insulate the nozzle shield and the nozzle tip from one another while transferring thermal energy therebetween.
