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]
Plasma arc welding has a greater energy concentration as compared to GTAW. A deep, narrow penetration is achievable, with a maximum depth of 12 to 18 mm (0.47 to 0.71 in) depending on the material. [2] Greater arc stability allows a much longer arc length (stand-off), and much greater tolerance to arc-length changes.
CNC plasma cutting Plasma cutting performed by an industrial robot. 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.
The F-Arc is born out of Voltage and initiates around V (F-Arc_init_min), and the F-Arc plasma is maintained at or above the minimum-arc-current of I (arc_plasma_min). [8] While arcing occurs during both the BREAK and MAKE transitions, the break arc is typically more energetic and thus more destructive. [8] [9] [10] Potential MAKE F-Arc plasma ...
The voltage required to arc this distance is 327 V, which is insufficient to ignite the arcs for gaps that are either wider or narrower. For a 3.5 μm gap, the required voltage is 533 V, nearly twice as much. If 500 V were applied, it would not be sufficient to arc at the 2.85 μm distance, but would arc at a 7.5 μm distance.
The flow rate DOES change, as the plasma reacts to the electric field in the torch and on the workpiece. - Toastydeath 04:24, 5 December 2006 (UTC) To give an idea of the flow rate while plasma cutting: The flow of a Hypertherm plasma 260A for mild steel uses 42 l/min for the plasma gas (O2) and 104 l/min for the shield gas (air).
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 ...
Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) and metal active gas (MAG) is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to fuse (melt and join).
