Question 1

Is Argon gas necessary for a plasma cutter?

Accepted Answer

There are mainly five gasses present in the plasma cutter: Argon, air, hydrogen, Oxygen, and nitrogen. These five gasses should be present in a plasma cutter to cut the thick metals. 

Your work is incomplete without combining all of these gasses. If the thickness of the material is more significant than 1.5 inches, it requires excellent pressure. So you always need an organ for a Plasma cutter, especially if the thickness of the metal is more than 1.5 inches.

Question 2

What size air compressor can you use to run a plasma cutter?

Accepted Answer

The air compressor must be big if you want to use it for plasma cutting. According to manufacturers, the air compressor must be 1.5 times the CFM of your cutter. If there is a need for an air compressor with 4 CFM, you must go with 6 CFM of the air compressor.

So, in other words, if the CFM is higher, then it also helps you save your time and pressure. Also, there will be no interruption between the work when the air compressor has high CFM.

However, it also depends on the nature of your work. For example, you can also use small compressors for longer cuts if not using the cutter. Small or medium size compressors have the capacity of 30 gallons of air at 5 CFM.

Question 3

Can we use plasma cutters for cutting high carbon Steel?

Accepted Answer

Surprisingly, you can cut different materials with the plasma cutter, including different steels. So you can easily cut high carbon steel, stainless steel, aluminum, brass, alloy steel, copper, and other types of materials with the help of a plasma cutter.
