2. Plasma arc welding - Wikipedia

   en.wikipedia.org/wiki/Plasma_arc_welding

   Plasma arc welding (PAW) is an arc welding process similar to gas tungsten arc welding (GTAW). The electric arc is formed between an electrode (which is usually but not always made of sintered tungsten) and the workpiece. The key difference from GTAW is that in PAW, the electrode is positioned within the body of the torch, so the plasma arc is ...

3. Plasma cutting - Wikipedia

   en.wikipedia.org/wiki/Plasma_cutting

   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 ...

4. Plasma torch - Wikipedia

   en.wikipedia.org/wiki/Plasma_torch

   Plasma torch. A plasma torch cutter. 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]

5. Talk:Plasma cutting - Wikipedia

   en.wikipedia.org/wiki/Talk:Plasma_cutting

   2 "Plasma cutters working near sensitive electronics, such as CNC hardware or computers, use the contact start method. The nozzle and electrode are in contact. The nozzle is the cathode, and the electrode is the anode. When the plasma gas begins to flow, the nozzle is blown forward."

6. Air carbon arc cutting - Wikipedia

   en.wikipedia.org/wiki/Air_carbon_arc_cutting

   Air carbon arc cutting, also referred to as metal arc gouging, and previously as air arc cutting, [1] is an arc cutting process where metal is cut and melted by the heat of a carbon arc. Molten metal is then removed by a blast of air. It employs a consumable carbon or graphite electrode to melt the material, which is then blown away by an air ...

7. Plasma gasification commercialization - Wikipedia

   en.wikipedia.org/wiki/Plasma_gasification...

   Plasma gasification is in commercial use as a waste-to-energy system that converts municipal solid waste, tires, hazardous waste, and sewage sludge into synthesis gas (syngas) containing hydrogen and carbon monoxide that can be used to generate power. Municipal-scale waste disposal plasma arc facilities have been in operation in Japan and China ...
