Plasma cutting is made possible by introducing electricity into compressed air to create an ionized, imbalanced plasma gas. Oxyfuel cutting is where an oxygen fuel gas flame preheats the material to its ignition temperature, then a powerful oxygen jet is directed at the material.Click to see full answer. Then, is a plasma cutter better than a cutting torch?Plasma does not require the metal to be preheated before cutting, which saves time, and plasma cutters also outperform oxy-fuel torches when cutting stacked metals. Faster speeds can be achieved on thinner metals with plasma, with minimal or no metal distortion.Similarly, what kind of gas do you use with a plasma cutter? Argon gas Considering this, do you need gas for plasma cutting? Plasma Cutting – Recommended Gases. Compressed Air is the most commonly used gas for lower current plasma cutting and works well for most metals from gauge thickness to 1 inch. It leaves an oxidized cut surface. Compressed air can also be used for plasma gouging on carbon steel.Can you oxy fuel cut aluminum?Oxy-fuel cutting cannot cut non-ferrous metals such as aluminum, stainless, brass or copper.
