摘要： 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 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. Exemplary spring elements include wave spring washers, finger spring washers, curved spring washers, helical compression springs, flat wire compression springs, and slotted conical discs.

摘要： 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.

摘要： A nozzle for a plasma torch can include a body that has an inner surface, an outer surface, a proximal end, and an exit orifice at a distal end. The nozzle can also include a liner surrounded by the inner surface of the body. The liner can include a proximal end and an exit orifice at a distal end adjacent the exit orifice of the body. The nozzle can include at least one vent passage formed in the body. The vent passage can have an inlet formed in the inner surface of the body and an outlet formed in the outer surface of the body. The vent passage can be disposed between the proximal end of the body and the proximal end of the liner. The plasma arc torch can include a configuration that allows for increased electrode life and nozzle life for a vented high current plasma process.
