Pressing the cutting
lever creates a high
pressure jet of oxygen
to blow away molten
steel.~

cutting steel, the oxygen
actually burns the steel
which creates enough heat to
maintain the cut. Notice the

body wide open. This allows two oxygen
velocities, one for pre-heating, another
high-pressure one for actual cutting.~
