The working gas that Plasma Cutting machine cooperates to differ is OK cut all sorts of oxygen cut hard the metal of cut, especially to nonferrous metal (steel of stainless steel, carbon, aluminous, copper, titanium, nickel) cut effect is much better; Its are main when the advantage depends on the metal with cut not big ply, plasma Cutting rate is rapid, be in especially cut is average when carbon steel thin plate, the 5~6 that speed can amount to oxygen patterning method times, cut side is bright and clean, hot be out of shape small, affect an area without heat almost. Plasma Cutting machine develops at present, adoptable job gas (the electric medium that working gas is plasma arc, it is the body that carry heat, the melt metal in excluding cut even at the same time) have apparent effect to the cut character of plasma arc and cut quality, speed. Gas of commonly used plasma arc job has argon, hydrogen, nitrogen, oxygen, air, vapor and certain gas mixture. Plasma Cutting machine is applied extensively wait for all trades and professions at machine of industry of machinery of car, engine, pressure vessel, chemical industry, nucleus, current mechanism, project, steel structure! Plasma is gotten in connecting associate vapor such safety, handy, effective, muti_function and the method of environmental protection is right 0. The metal of 3mm above ply undertakes hot-working is handled (cut, fusion welding, drill rod solder, quench, spray is waited a moment) , this machines the fact on industrial history to belong to initiate in the metal.
