• AC: An electric current that reverses its direction many times a second at regular intervals, typically used in power supplies.
  • Angularity: Measurement of the plasma cut angle.
  • Auto-voltage™ circuit: Input sensing that allows the system to run on a variety of voltages with no rewiring.
  • Bitmap
  • Blow-back: Patented technology provides a pilot arc, which is a small pocket of plasma gas. A high-voltage, low current circuit is used to initialize a very small high-intensity spark within the torch body which generates the pilot arc.
  • Boost Conditioner™ circuit: Hypertherm technology that compensates for input voltage variations.
  • Burr – A thin ridge or roughness left on forgings or sheet metal blanks by cutting operations such as slitting, shearing, trimming, blanking, or sawing. Deburring is smoothing the rough cut edges of metal. Click here to see more on //ROTOCLEAN//: deburring tumbler
  • Bypass – A generic term referring to the amount that one steel passes over or through another piece of steel.
  • CNC: Computer Numeric Control, the automation of machine tools operated by programmed commands.
  • Coaxial-assist™ jet: Patented jet design boosts cutting speed as much as 20% over conventional designs.
  • Cut surface: The area of the plasma table that holds the material to be cut.
  • Drag Lines – grooves in the cut surface that are the result of a plasma arc (see also: Lag Lines)
  • Dross: Waste material from plasma or oxyfuel cutting processes.
  •  
  • Dual-threshold™ pilot circuit: Hypertherm technology that significantly reduces nozzle wear by increasing the pilot current precisely when needed.
  • Ductility – a measure of the extent to which a metal can be deformed or bent before fracture a fracture occurs.
  • Duty Cycle – refers to the percentage of time (in any interval) that the plasma arc can be cutting
  • Dxf file: Drawing Exchange Format, a CAD data file format that works for exchanging and using information between AutoCAD and other programs.
  • Electric arc: An electrical breakdown of a gas which produces an ongoing plasma discharge.
  • ETR (Easy Torch Removal): A unique connector design that provides easy switching between hand and machine torches.
  • FineCut™: A line of Hypertherm consumables that deliver significant improvements in cut quality on thin-plate metals by providing a narrow kerf width, reduction in dross, and virtually no heat-affected zone.
  • G3 Series
  • Heat-affected zone (HAZ): The area on the material where its micro-structure and properties are altered due to welding or heat intensive cutting.
  • HyLife® Electrodes: that last longer than ordinary electrode designs by using the same patented technologies developed for advanced Hypertherm mechanized systems.
  • Kerf: A slit made by cutting.
  • Lag lines: Ridges in the surface of the cut. (see also: Drag Lines)
  • Metal Fabrication: The building of machines, structures and other equipment, by cutting, shaping and assembling parts made from raw materials.
  •  
  •  
  • Nesting: The positioning of parts to minimize material waste.
  • Oxy-fuel: A cutting process that requires pre-heating of the material to the point where a high-power torch is able to direct a stream of oxygen through the material to burn it away.
  • Plasma: A distinct phase of matter, separate from solids, liquids, and gases, frequently described as a hot “ionized gas.”
  • Plasma cutting: A process used to cut metals. Gas is forced through a nozzle along with an electrical arc turning some of that gas into plasma, hot enough to melt the material being cut.
  • Raster
  • Vector
  • Water Table: A cut surface where particles or fumes are pushed into the water so none remain in atmosphere.
  • Welding: The process of joining metals by melting the parts.
  • Zoned Downdraft: A cut surface where particles and fumes are transferred through a filter system to clean the air.
