Abstract: The invention features methods and apparatuses for establishing operational settings of a plasma arc cutting system. A plasma power supply includes a user selectable control. The user selectable control enables selection of a single cutting persona that establishes at least a current, a gas pressure or gas flow rate, and an operational mode of the plasma arc cutting system.

Abstract: In some aspects, a plasma processing torch can include an end portion that receives at least one gas and at least one power input; a first joint coupled to the end portion, the first joint conveying the gas and power through the first joint; a middle portion coupled to the first joint, the middle portion conveying the gas and power through the middle portion; a second joint coupled to the middle portion at an end opposite the first joint, the pivot joint conveying the gas and power through the pivot joint; and a head portion coupled to the second joint, the head portion conveying the gas and power to a torch tip to generate a plasma arc.

Abstract: A thermal processing torch can include a torch housing having a head portion pivotally coupled relative to a body portion with a joint portion. The torch also can include a pivotal connector simultaneously pivoting about a common axis with the joint portion of the torch housing. The pivotal connector can include an electrically conductive wall conducting an electrical current between the body portion of the torch housing and the head portion of the torch housing. The pivotal connector can also include a passage provide a processing gas between the body portion of the torch housing and the head portion of the torch housing.

Abstract: The system disclosed herein is an interface that allows the drafter of a technical document, such as a patent application, to keep both element names and reference numerals consistent throughout a text document and any accompanying documents, including drawings. The system creates and manages a global table of terms that may be edited globally and applied to both a text document and a drawing file. The system also provide for the examination and correction of a technical document that used element names and reference numerals to ensure consistency.
