The discharge lamp10 includes a discharge vessel16 with electrodes 20 for generating an electrical arc.

The discharge lamp (10) comprises a sealed discharge vessel and two electrodes (22) to produce an arc.

The arc lamp includes first and second electrodes for generating a high power plasma arc within the inner envelope, the arc emitting the radiation.

The invention relates to an emissive element (26) for supporting an electric arc in a plasma arc torch (10) using an oxygen gas to create the plasma.

Each modular unit may include an electrode and a cathode spaced apart and configured to generate an arc therebetween.

An element (109) for producing a triggered arc is installed between two electrodes (103,104) to form a trigger circuit.

The power supply (16) is coupled to the welding wire feeder (20) and configured to produce a welding arc (12).

The invention relates to a high-frequency device for generating a plasma arc (5) for the treatment of biological tissue (1), notably in medicine.

A welding electrode (22) is connected to the power converter (32) to receive electrical energy therefrom and produce an electric arc (20).

The element includes a body (20) having a front face (29) for supporting the electric arc which is defined by at least two distinct components formed from different materials.

A drop of water or prism of glass can spread out visible sunlight into a rainbow of colors.

In 1813, chemist Humphrey Davy succeeded at producing an electric arc that gave off light.

Remember that a 600-volt circuit has a far greater capacity to produce an electrical arc than a 12-volt circuit.

The number of turns of the arc generating winding (W22) is determined by no-load voltage, and the current is determined in accordance with the power for generating arc.

When the edge is worn to produce an arc with a radius of about 0.10 mm, it is sharpened.
