Which cutting technology creates an extremely hot plasma to cut metal and can be precise?

• A. Water Jets
• B. Laser Cutting
• C. Plasma Cutter
• D. Oxyacetylene Torch

Answer: (C)

Plasma cutting uses an electric arc that ionizes gas into plasma, creating temperatures hot enough to melt metal and a high-velocity plasma jet that blows the molten material away to form a precise cut. This combination makes it capable of clean, accurate cuts on conductive metals across a range of thicknesses. Water jets rely on high-pressure water (sometimes with abrasive) and don’t use heat, laser cutting uses a focused light beam rather than plasma, and oxyacetylene torches burn fuel with oxygen but don’t produce the extreme heat of plasma. That distinctive hot plasma cutting action is why this option fits the description.
