Plasma Cutting

 

Plasma cutting is a process used to cut steel and other metals (or sometimes other materials) using a plasma torch, which uses a powerful electric arc to create plasma out of a blast of ordinary dried air to vaporize or literally "plasmatize" the medium which is being cut.

 

The torch uses a two cycle approach to producing plasma. First, a high-voltage low current circuit is used to initialize a very small high intensity spark within the torch body, thereby generating a small pocket of plasma gas. When cutting begins, the second circuit trips in and changes the current to a low-voltage high current circuit, thereby initiating a high-speed powerful jet of plasma, which travels at over 15,000 km/h.
