Table plasma cutting machine can cut different metals. Plasma cutting machine need different gas to cut different materials.
1.Table plasma cutting machine match with argon gas.Argon don’t react with any metal at high temperatures. Argon plasma arc is very stable. Moreover, table plasma cutting machine nozzle and electrode used have higher service life.Argon plasma arc valtage is low, the cutting ability is limited. Compared with air cutting, its cutting thickness will be reduced by about 25%.In addition,argon plasma arc will make a lot of slags.
2.CNC plasma cutting machine match with oxygen. Oxygen can improve the cutting speed when cutting low carbon steel. When plasma cutting machine stop cutting, it is alike with flame cutting.Oxygen plasma arc make plasma cutting machine cutting speed is faster in high temperatures.CNC cutting machine electrode will be damaged easily. So we need oxidation electrode to prolong electrode life.
3.Plasma cutting machine match with hydrogen.Hydrogen is often used as an auxiliary gas mixed with other gases.Such as the H35 (gas volume fraction of hydrogen is 35%, the other is argon) is one of common gas.The plasma arc cutting ability is the strongest.Metal of more than 70mm thickness, we often use argon + hydrogen as plasma cutting machine cutting gas.
4.CNC cutting machine match with nitrogen. Nitrogen is used as a working gas.Nitrogen plasma arc stability is good and the jet power is higher than argon.So the slag is less than argon. Nitrogen can be used alone and can also be mixed with other gas.Nitrogen is sometimes used as an arc gas for cutting oxygen plasma arc
