If you\u2019re looking to make quick, smooth and clean cuts through a variety of metals a plasma cutter is your best solution.<\/h2>\n

\"Plasma<\/p>\n

Plasma cutters can be used with a manual hand torch or fitted to a CNC cutting table often know as a profile or plate cutter.<\/p><\/p>\n\n\n\n\n\n

<\/p>\n\n\n\n

However, you must know which gases are suitable to guarantee optimum performance and high-quality results. But, depending on the metal which you\u2019re cutting, you\u2019ll require different types of gases<\/a> or a special combination. So, we\u2019ve put together a complete breakdown of the plasma cutter recommended gases<\/strong> showing what metals they\u2019re fit to cut.<\/p>\n\n\n\n

4 Recommended Plasma Cutting Gases<\/h3>\n

\"manual<\/p><\/p>\n\n\n\n\n\n

Compressed Air<\/h3>\n

Compressed air is a highly versatile plasma gas which produces top quality cuts on mild and stainless steel as well as aluminium. But, it\u2019s also suitable for plasma extraction on carbon steel. It\u2019s also a low-cost gas as you won\u2019t need to purchase it. However, you still must clean it to remove any particles, moisture or oil mist. You can use compressed air to cut metals with a thickness of up to 1 inch. However, you\u2019ll achieve an oxidized cut area which could affect the weldability of the cut\u2019s edge.<\/p><\/p>\n\n\n\n

<\/p>\n\n\n\n

Oxygen<\/h3>\n

Oxygen has become popular for cutting through mild steel thanks to the clean cuts and fast cutting speeds provided. It\u2019s not recommended for cutting aluminium or stainless steel plates. In contact with carbon steel, oxygen plasma gas products a fine spray of melted metal and each drop has a low surface tension but which is easy to eject from the kerf. The downside of oxygen is the expensive price and the short life of the consumables. However, high-end plasma cutting systems use nitrogen with oxygen plasma to achieve the same results.<\/p><\/p>\n\n\n\n

Nitrogen<\/h3><\/p>\n\n\n\n

Nitrogen is typically used for high current plasma machines and to cut metals with a thickness of up to 3 inches including mild and stainless steel or aluminium. You\u2019ll achieve an excellent quality cut and enduring parts life. However, for thicker metals, you should use a mix such as argon-nitrogen. In general, air is the best secondary gas when you\u2019re using nitrogen plasma. But, you can also use carbon dioxide which improves the cut\u2019s finish and increases the cutting speed.<\/p>\n\n\n\n

About the Argon-Hydrogen Mix<\/h3><\/p>\n\n\n\n

The argon-hydrogen mix is usually suitable to cut through stainless steel or aluminium. The standard combination of the mix is 65% argon and 35% hydrogen. It offers the maximum cutting capacities and it\u2019s the hottest plasma burning gas. You\u2019ll achieve an excellent and clean cut. The argon-hydrogen mix is required for mechanical cutting of any type of materials which exceed a 3 inches thickness. But, it\u2019s also suitable for plasma gouging on any materials.<\/p>\n\n\n\n
