Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel , stainless steel , aluminum , brass and copper , although other conductive metals may be cut as well.
A plasma torch (also known as a plasma arc, plasma gun, plasma cutter, or plasmatron) is a device for generating a directed flow of plasma. [1] [2] [3] The plasma jet can be used for applications including plasma cutting, plasma arc welding, plasma spraying, and plasma gasification for waste disposal. [4]
This is an autogenous process and normally does not use filler wire or powder. Medium plasma uses current between 10 and 100 amps and is used for higher-thickness plate welding with filler wire or autogenous up to 6 mm (0.24 in) plates and metal deposition (hardfacing) using specialised torches and powder feeders (PTA) using metal powders.

Propane does not burn as hot as acetylene in its inner cone, and so it is rarely used for welding. [12] Propane, however, has a very high number of BTUs per cubic foot in its outer cone, and so with the right torch (injector style) can make a faster and cleaner cut than acetylene, and is much more useful for heating and bending than acetylene.
Some hot dogs are made of pieces of meat cut away from beef and pork, while others include chicken or turkey that’s been separated from the bones (labeled as “mechanically separated”).

The hot dogs are then placed in cold water to cool completely, and in the case of skinless hot dogs, separate the cellulose casing from the finished frankfurter.
