The Importance of Air in Plasma Cutting

Why do plasma cutters use air?
The most commonly used plasma cutter gas type is air. Highly versatile and inexpensive, compressed air works well for lower current cutting and on most metals-mild steel, stainless steel, and aluminum–from gauge sizes to one-inch thickness.

Stainless steel, aluminum, and copper may all be effectively and widely cut using the plasma cutting technique. A plasma cutter cuts metal easily by producing a plasma stream by passing an electric arc through a gas. Air is one of the most often used gases in plasma cutting. How deep can plasma cutters cut, and why do they utilize air? Air is used by plasma cutters, but why?

Air is a popular choice for plasma cutting since it is easily accessible and reasonably priced. Air is safer to use than other gases like acetylene or propane because it is non-toxic and inflammable. Air can also provide a high-quality cut with little dross or slag when utilized in a plasma cutter.

Ionizing gas molecules during the plasma process causes them to release energy as heat and light. Ionized air molecules produce a plasma stream that is hot enough to melt metal and easily cut through it. The plasma torch is kept cool by the air, which keeps it from overheating while making a cut. How far can a plasma cutter go when cutting?

The thickness and kind of the metal, the plasma cutter’s amperage, and the speed at which the cutter is carried across the metal are some of the variables that affect the depth to which it can cut. A plasma cutter can typically cut through metal up to an inch thick, however some powerful plasma cutters have a maximum cutting depth of two inches or more.

Does hardened steel undergo plasma cutting in this regard? Yes, hardened steel can be sliced using plasma cutting. Due to its increased hardness, hardened steel is often more challenging to cut than conventional steel, although a powerful plasma cutter may still easily cut through it. When cutting hardened steel, the cutting speed could be slower, and the plasma cutter would need to be adjusted for a smooth cut.

A laser is it a plasma cutter?

Yes, a laser is not a plasma cutter. Both techniques are used to cut metal, although they operate in distinct ways. A plasma cutter utilizes an electric arc to ionize gas molecules and form a plasma stream that can cut through metal, as opposed to a laser cutter, which uses a powerful laser beam to cut through metal. Additionally, compared to plasma cutters, laser cutters are often more expensive and more exact.

As a result of its accessibility, safety, and capacity to make a high-quality cut, air is a crucial component in plasma cutting. Plasma cutters are a popular option for metal manufacturing and construction because they can cut through a variety of metal kinds, including hardened steel. They are a strong and effective tool for cutting metal, despite not being lasers.
