The operation of most plasma cutting systems relies on a compressed gas source. This gas performs several crucial functions within the cutting process, including creating the plasma arc, removing molten material, and cooling the torch components. A common gas used for this purpose is compressed air, which is readily available and cost-effective for many applications.
The use of a gas source is integral to the efficiency and quality of the cut produced by the majority of plasma cutting setups. Historically, compressed air has provided a practical solution, enabling portability and relatively low operational costs. The selection of a suitable gas plays a significant role in determining the types of metals that can be cut and the overall speed and precision of the operation.
