The invention relates to a wear part for an arc torch, plasma torch or plasma cutting torch, characterised in that the wear part or at least one part or a region of the wear part consists of an alloy formed from silver and zirconium, silver and hafnium, or silver and zirconium and hafnium.

Method and apparatus for monitoring and diagnosing gun performance is derived that can determine proper gun operation and if not operating properly diagnose potential causes for abhorrent operation. The voltage produced by the gun is sampled in real time and the frequency spectrum produced analyzed using FFT and then reducing the FFT pattern down to a set of numerical values or a signature that can be compared to known signatures for both correct operation and abnormal operation. Using best fit techniques the cause of any abnormal behavior can then be identified. The method can also be used to predict the end of hardware life and aid in production scheduling and spare parts acquisition by providing advanced notice of wear and usage.

An inductively coupled plasma (ICP) torch is described that includes an injector protector to shield an injector end. A system embodiment includes, but is not limited to, a tubular sample injector configured to receive an aerosolized sample in an interior defined by walls of the tubular sample injector; an injector protector surrounding at least a portion of the tubular sample injector; an inner tube surrounding at least a portion of the injector protector to form a first annular space between the inner tube and the injector protector, the inner tube defining at least one inlet port for introduction of an auxiliary gas into the first annular space; and an outer tube surrounding at least a portion of the inner tube to form a second annular space, the outer tube defining at least one inlet port for introduction of a cooling gas into the second annular space.

Description of a method and equipment for panel (900) treatment in the manufacture of printed circuit boards that includes the following phases: setting up a panel (900) with a first side (905), a second side (910) opposite the first side, and at least one through hole (915) in the thickness of the panel; positioning the opening (205) for an intake system (200) in contact with the first side (905) of the panel (900) so this opening (205) delimits a portion on the first side (905) containing the through hole (915); creating negative pressure within the intake system (200) and simultaneously exposing at least one portion on the second side (910) of this panel (900) to a flow of plasma, whereby this portion on the second side (910) contains the through hole (915).

This specification describes systems, methods, and architectures related to generating a plasma shield for laser operations. An example system for generating a plasma shield includes a laser head for directing a laser beam towards a target area on a workpiece. The path of the laser beam from the laser head to the target area on the workpiece is substantially surrounded by a plasma shield, which may form a gas-impermeable barrier. The plasma shield is configured to prevent the ingress of atmospheric or environmental gases, for example oxygen, into an area which would allow the gas to be in contact with the area of the workpiece being interacted with by a laser beam. The shape or location of the plasma shield may be controlled or altered using a magnetic field.

The present inventive concept relates to a device for treating an exhaust gas, and more particularly, to a plasma device capable of, even when connected to a vacuum pump, extending a lifetime of an electrode of a plasma torch. In the plasma device according to the present inventive concept, since an orifice is installed in a connection unit for connection with a vacuum pump to prevent a decrease in pressure of the vacuum pump, a pressure of a plasma reaction unit including the plasma torch of the plasma device can be maintained similar to normal pressure, thereby reducing the wear of a tungsten electrode in the plasma torch to extend a lifetime of the electrode.
