ABSTRACT:
A cutting torch allows the preheat oxygen and fuel valves to remain in a preset position while the torch is off. The cutting torch has preheat oxygen and fuel cutoff valves mounted in line with the adjusting valves. The cutoff valves are both operated linearly, each having an axially moving plunger. An actuator simultaneously moves the cutoff valves between opened and closed positions. The actuator has a locking device to lock them in the opened and closed positions. A pilot flame igniter utilizes a piezoelectric crystal and a pilot fuel valve positioned side by side with parallel axes. An igniter actuator in a single stroke opens the pilot fuel valve and causes an electrical spark to ignite the pilot flame.
