How can operators ensure maximum efficiency while cutting?

• A. By restricting the oxygen supply.
• B. By ensuring proper flame adjustment and cutting speed.
• C. By using extra oil to lubricate the cutting tip.
• D. By alternating between different gas mixtures.

Answer: (B)

To achieve maximum efficiency while cutting, ensuring proper flame adjustment and cutting speed is crucial. The flame must be set correctly—neither too oxidizing nor too carburizing—so that it adequately preheats the metal without excessive fuel or oxygen that could lead to inefficient cuts or poor quality. Additionally, the operator must maintain an appropriate cutting speed. If the speed is too slow, it may lead to excessive heat input, causing distortion or excessive oxide buildup on the cut. Conversely, if the speed is too fast, the cut may become uneven and the kerf may be wider than desired, leading to wastage of material and time. Properly balancing flame characteristics and cutting speed allows for clean, efficient cuts that minimize material loss and optimize the cutting process. Other methods mentioned, such as altering oxygen supply, using lubricants, or changing gas mixtures, do not effectively contribute to cutting efficiency and may complicate the process or lead to increased costs and risks without offering improved results.
