The gas inlet tube 1 is surrounded as far as its downstream end by a coaxial sleeve 2 which meets a waveguide 3 at right angles. The guide is bounded, on the side opposite the microwave generator, by a fixed wall 18 perpendicular to its Y-Y axis and the sleeve 2 is bounded, on the side opposite the gas outlet nozzle 8, by another fixed wall 13 perpendicular to its X-X axis. Application to the welding and cutting of metal objects. <IMAGE>
