Plasma Cutters

Plasma cutters work by sending an inert pressurized gas, such as nitrogen, argon, or oxygen, through a small nozzel. In the center of this nozel exists a negatively charged electrode. When current is sent to the negative electrode, the current will arc between the electrode and the metal surface, thus creating a complete circuit. This arc, when combined with the powerful flow of the inert gas, forms into a plasma arc that acts as a hot knife through butter. You can purchase a whole range of plasma cutters online at discount prices.
