What is the correct sequence of steps for cutting steel?

The correct sequence for cutting steel begins with preparing the metal surface. This step is crucial because a clean surface free of contaminants, rust, or paint is necessary for effective cutting. It ensures that the proper chemical reaction occurs during the oxy-fuel cutting process. Once the surface is properly prepared, the next step is to light the torch. This involves a specific technique to safely ignite the oxy-fuel mixture, thereby producing the cutting flame. Finally, holding the torch correctly allows for precise and controlled cutting along the intended line. Following this order promotes safety and efficiency in the cutting process.

The other sequences do not reflect the optimal safety and effectiveness needed in oxyfuel cutting. Lighting the torch before preparing the surface could lead to unsafe conditions or ineffective cutting if the surface is not ready. Similarly, holding the torch before lighting or preparing the surface does not follow the logical flow needed for successful cutting. Each component of this process plays a vital role in achieving clean cuts and ensuring operator safety.
