Abstract
A portable, low-pressure propane gas torch including an internal spark igniter is characterized by the absence of the heretofore conventional venturi. Particular ratios of the inside diameters of the orifice member outlet and the burner tube provide an optimum mixture of flammable gas and aspirated air.
