Why are some plasma torches designed to swirl the plasma gas?
Considering this, what effect does the swirling of the plasma gas have?
This causes much higher temperature near the cathode. It is indicated that swirl gas accelerates cathode erosion for two reasons: increasing plenum chamber pressure and changing flow patterns in the vicinity of the cathode.
Furthermore, what gas does a plasma cutter use? Plasma cutters work by sending an electric arc through a gas that is passing through a constricted opening. The gas can be shop air, nitrogen, argon, oxygen.
Also to know is, what is a plasma torch used for?
A plasma torch (also known as a plasma arc, plasma gun, or plasma cutter, plasmatron) is a device for generating a directed flow of plasma.
Why is the body on a manual plasma torch made from a special type of plastic?
It has to withstand the high temperatures, ultraviolet light, and impact. air for low power, water for high powered torches.
