A segmental torch tip for mixing and combustion of gases whereby a plurality of segments are coupled together in fluid-tight relationship to provide a torch tip of variable size and shape. Each torch tip segment is provided with a plurality of gas passages that may be coupled in fluid-tight relationship with gas passages of each of the other segments, and the gases are supplied to the torch tip from sources via connections coupled to only one of the segments. A plurality of gas jet apertures are provided in fluid communication with the gas passage in each segment to permit mixing and combustion of the gases as they escape from the torch tip, and each of the segments may have one cross section of trapezoidal shape so that the torch tip forms an arc to permit concentration of flame and heat in a predetermined area.
