Abstract: An elongated wand defining pipe structure including inlet and outlet ends is provided. The inlet end may have a source of flammable gas under pressure communicated therewith and the outlet end includes discharge structure for discharging a jet of the gas from the pipe structure. A generally cylindrical shroud is loosely telescoped over the outlet end of the pipe structure and shroud support structure is carried by the pipe structure intermediate the inlet and outlet ends with the support structure defining a generally cylindrical recess opening outwardly at one end thereof along the pipe structure toward the discharge structure. One end of the shroud is removably and supportively telescoped into the recess and the other end of the shroud projects endwise outwardly beyond the discharge structure.
