A fuel combuster such as a torch tip, having means fixed ignition means and means for encapsulating the same. The combustion device comprises a metallic elongated tube having a forward section terminating in a front end, a middle section and a rearward section, the middle section communicating at its respective ends with the forward section and the rearward section. The rearward section is adapted, suitably at its rearward end, for connection to a source of combustible gas, and is suitably provided with axially positioned fuel jet means for injecting combustible gas into the tube and with apertures for intake of combustion supporting gas to be mixed with the combustible gas. A spring-loaded piezo crystal is affixed to the middle portion and is activated by grasping a cap assembly encapsulating the piezo crystal and applying a downward force thereto. The device can be ignited regardless of the orientation of the torch tip on the gas supply source.
