2, hydrogen is often as auxiliary gas and other gas mixing action, such as the famous gas H35 (the volume fraction of hydrogen is 35%, the rest of the argon) is one of the strongest gas plasma arc cutting, the main enrichment in hydrogen. Because the hydrogen can significantly improve the arc voltage, the hydrogen plasma jet has a high enthalpy value, when mixed with argon, the cutting ability of the plasma jet is greatly improved. Generally more than 70mm thickness of metal materials, commonly used argon + hydrogen as a cutting gas. If the water jet is used to further compress the argon + hydrogen plasma arc, the higher cutting efficiency can be obtained.
 
3, nitrogen is used as a working gas, under the conditions of higher voltage and nitrogen plasma arc has better stability and higher than the argon gas jet power, even if is cutting liquid metal viscosity materials such as stainless steel and nickel base alloy, incision of inferior hanging slag quantity are few. Nitrogen can be used alone, also can use with other gas mixture, such as automatic cutting often use air or nitrogen as the working gas, the gas has become the standard high speed cutting carbon steel gas. Sometimes nitrogen is also used as an arc gas in the plasma arc cutting.
 
4, oxygen can improve the speed of cutting low carbon steel materials. Use oxygen cutting, cutting mode and flame cutting is very similar, the plasma arc of high temperature and high energy of the cutting speed faster, but must with the use of high temperature oxidation resistance of electrode, and the electrode for arc anti impact protection, to prolong the electrode life.
 
5, an air containing volume fraction of about 78% nitrogen, so use air cutting formed by hanging slag and nitrogen gas cutting is very similar; in the air also contains a volume fraction of about 21% oxygen, because the existence of oxygen, air cutting speed of low carbon steel material is also very high; at the same time the air is the most economical working gas. However, when the air is used to cut, there are problems such as hanging slag and cutting oxidation, increasing nitrogen, and the lower life of electrode and nozzle can also affect the working efficiency and cutting cost.
