摘要： A plasma cutting system is provided. The system includes a power source configured to generate a plasma arc, and a plasma arc torch connected to the power source for delivering the plasma arc to a workpiece. The plasma arc torch defines a multi-function fluid flow path for sustaining the plasma arc and cooling the plasma arc torch such that the plasma cutting system has a power-to-gas flow ratio of at least 2 kilowatts per cubic feet per minute (KW/cfm). The power-to-gas flow ratio comprises a ratio of power of the generated plasma arc to a total gas flow supplied to the plasma arc torch.

摘要： The invention relates to a plasma source with an oscillator having an active element and a resonator connected to the active element. The resonator has a hollow body, a gas inlet, a gas outlet arranged at a distal end of the hollow body about a longitudinal axis of the hollow body, and a coil arranged along the longitudinal axis of the hollow body, said coil having an effective length of one quarter of a wavelength at a resonant frequency of the resonator. A distal end of the coil is arranged relative to the gas outlet such that a plasma section can form between the distal end of the coil serving as a first plasma electrode and the gas outlet of the hollow body serving as a second plasma electrode. At a proximal end of the hollow body, the coil is lead out of the interior of the hollow body through an electrically contact-free feed-through, and a proximal end of the coil contacts the hollow body at its external side. At a first contact region located between the proximal end of the coil and the feed-through, the coil is coupled to a first gate of the active element, and at a second contact region located between the proximal end of the coil and the feed-through, the coil is coupled to a second gate of the active element.
