Claims

[Scope of utility model registration request]

A crater a is composed of pipes 3 and 4 with an inner and outer heavy structure forming a cut oxygen flow path 1 and a combustible mixed gas flow path 2, and has flow path portions 5 and 6 communicating with both flow paths 1 and 2, respectively. A torch head b1 fixedly supporting the crater a in a removable and replaceable manner includes a pipe group C for supplying cutting oxygen and flammable mixed gas to each of the flow path sections 5 and 6, and a cutting oxygen flow path section of the torch head b. 5 includes a piezoelectric element 7 whose position is fixed and an actuator 8 that moves toward the piezoelectric element 7 and acts on it due to the cutting oxygen pressure.
A piezoelectric mechanism d1 consisting of a piezoelectric mechanism d1, and an actuator retracting mechanism e for returning the actuator 8 to the standby position and holding the actuator 8 in the standby position as the cutting oxygen pressure decreases, and Spark electrode 11.1 at the tip of the crater a
In the automatic ignition type cutting torch, the piezoelectric mechanism d and the actuator retracting mechanism e are connected to the torch head b, which is connected to the piezoelectric element 2, and the piezoelectric element 7, and a supply tube group side head part b2 which movably accommodates and holds the actuator 8, and these divided head parts b1. An automatic ignition cutting torch characterized in that b2 is configured to be connected and fixed and detachable.
