Embodiment Construction

[0011] Reference will now be made in detail to various and alternative embodiments and to the drawings, in which like numerals represent substantially the same structural elements. Each example is provided by way of illustration, not limitation. In fact, it will be apparent to those skilled in the art that modifications and variations can be made without departing from the scope or spirit of the disclosure and claims. For example, features illustrated or described as part of one embodiment can be used on another embodiment to yield still a further embodiment. Therefore, it is intended that the present disclosure cover modifications and variations that come within the scope of the appended claims and their equivalents.

[0012] The present disclosure is generally directed to plasma arc torches useful in a variety of different cutting, welding and spraying operations. Specifically, embodiments of the present invention are directed to air-cooled plasma arc torches, while other ...

Abstract

A plasma arc cutting system and method is provided and provides a fixed arc start current until separation occurs between the torch nozzle and electrode. After separation the current is dropped to a low current level for a period of time and then current pulses are provided until a work current is detected in a work piece to be cut.

Description

technical field [0001] Apparatus, systems and methods consistent with the present invention relate to plasma cutting, and more particularly to apparatus, systems and methods related to plasma arc torches and components thereof. Background technique [0002] In many cutting, spraying, and welding operations, plasma arc torches are used. Through these torches, plasma gas jets are launched into the ambient atmosphere at high temperature. These jets are launched from the nozzle, and when they leave the nozzle, the jets are highly underexpanded and very concentrated. However, many components of the torch are susceptible to failure due to the high temperatures associated with the ionized plasma jet. This susceptibility to failure increases during arc transfer at the start of the plasma cutting operation. Damage caused by the plasma arc coming into contact with components within the torch at high current levels. Damage can cause premature failure of components, and this failure...
