Plasma cutting. 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. Plasma cutting is often used in fabrication shops ...
Basic mechanism. This is a basic explanation of how a pinch works. (1) Pinches apply a high voltage and current across a tube. This tube is filled with a gas, typically a fusion fuel such as deuterium. If the product of the voltage & the charge is higher than the ionization energy of the gas the gas ionizes. (2) Current jumps across this gap.
A plasma etcher, or etching tool, is a tool used in the production of semiconductor devices. A plasma etcher produces a plasma from a process gas, typically oxygen or a fluorine -bearing gas, using a high frequency electric field, typically 13.56 MHz. A silicon wafer is placed in the plasma etcher, and the air is evacuated from the process ...

Metalworking is the process of shaping and reshaping metals in order to create useful objects, parts, assemblies, and large scale structures. As a term, it covers a wide and diverse range of processes, skills, and tools for producing objects on every scale: from huge ships, buildings, and bridges, down to precise engine parts and delicate ...

Debye sheath. The Debye sheath (also electrostatic sheath) is a layer in a plasma which has a greater density of positive ions, and hence an overall excess positive charge, that balances an opposite negative charge on the surface of a material with which it is in contact. The thickness of such a layer is several Debye lengths thick, a value ...
I use two hand held plasma torches and an automated CNC plasma in my shop. I've never seen a hand held plasma torch that can cut 2" thick steel plate. My cutting table is 6' x 12' and uses a Hypertherm 130HSD. The dimensions on this unit are about 4' x 4' and it weighs more than 300', the maximum thickness it can cut with edge start is 1 1/2 ...
