Micro-beam plasma welder models

DML-V02a plasma welder plasma welder primary standard / extra functions Standard: Welder Features: 1. Digital type selection DSC processor, precise and accurate control of the output. Production of high quality components, reliable function. 2. "Speed ??Shuttle" function, a digital push button control multiple digital form, fault rate cuts to overcome the problems of frequent appearance potentiometer. 3. The energy density, the arc strong direction. Financial Permeability strong. Stable keyhole effect can occur, the effects can be obtained through the holes outstanding side welding. 4. The quality of the weld arc insensitive to change, because the plasma arc near to a cylindrical shape. Divergence angle is very small (about 5 degrees) and straight is good, heating mottled area has little effect when the curvature change, and thus obtain a uniform weld simple situation. 5. tungsten in water-cooled condensing inside the nozzle does not touch the workpiece, which can be useful to prevent the appearance of the weld metal clip tungsten. Other arc of agitation is good, melt pool temperature is high, it is conducive to the release of gas melt pool. 6. The plasma arc because of the high tightening effect and thermal ionization degree, when the current is smaller still stable welding current can be as small as 0.1A secure incineration, especially micro-fine parts suitable welding. After tightening the arc, the arc column will be set to guide a thin, current, stable arc, small molten pool, very narrow heat-affected zone, the electrode and the nozzle aperture subtle and finer arc column shortening together also progress thermal efficiency. Plasma refers to a standard atmospheric pressure at temperatures beyond 3000 ℃ of gas, the temperature at which the spectrum can be seen as following the solid, liquid, gaseous material situation after the fourth. Plasma is activated by a high child, electrons, atoms or molecules. For example: It may be subjected to lightning occurs in nature. From 1960 in future, the plasma of the word gained new meaning, that is high-energy situation arc through the swirl ring or nozzle tightening constituted, this principle is now widely used in iron and steel, chemical and mechanical engineering industries. A plasma arc welding approach is developed on the basis of the TIG ·. TIG welding using a heat source is free arc under atmospheric condition, referred to free tungsten arc. After tightening strengthening tungsten arc plasma arc welding heat source sucked comfortable and achieve higher degree of ionization of the arc plasma, said plasma arc, also known as tight arc. There is no physical difference between the two in essence, just is not the same degree of ionization in the arc column on the. After tightening the arc gather more energy density and higher temperature. Etc. Maximum voltage drop in the arc plasma arc column region, this is because the arc column is fierce austerity, the electric field strength is remarkably; increasing cause. Thus, the first is the use of plasma arc column plasma arc heat to heat the metal, but comfortable to use hot tungsten arc electrode region occurred two to heat the base material and the electrode metal.
