Abstract
The invention features methods and apparatuses for regulating a shielding liquid in a plasma torch. A liquid-injection shield for a plasma torch includes a body having an exterior surface and an interior surface and a liquid injection regulation component circumferentially disposed within and in direct contact with the interior surface of the body. The liquid injection regulation component and the interior surface of the body define a chamber. The liquid injection regulation component also defines a first set of ports sized to regulate a liquid entering the chamber and a second set of ports oriented to distribute a fluid exiting the chamber.
