What is the most commonly used plasma cutting gas?

• A. Nitrogen
• B. Argon
• C. Oxygen
• D. Compressed air

Answer: (D)

In plasma cutting, the gas that forms the plasma arc is most commonly plain compressed air. It’s the go-to because it’s inexpensive, readily available in most shops, and works well for cutting a wide range of metals, especially mild steel. Compressed air also helps blow away molten metal and helps keep the torch cooler during cutting, which keeps operation simple and economical for everyday 작업. Other bottled gases like nitrogen or argon are used only in more specialized setups to improve edge quality on certain materials or for specific process tweaks, and oxygen, while it can increase cutting speed on carbon steel, tends to cause more oxidation and edge finish issues, requiring different safety and process considerations. So, for general, all-around plasma cutting, compressed air is the standard choice.
