How is a torch lighter typically used?

A torch lighter is primarily designed for lighting high-temperature tools such as an acetylene or propane torch, making it suitable for tasks like welding, soldering, or other metalworking applications. Unlike conventional lighters, which may provide a less intense flame, a torch lighter produces a focused, adjustable flame that can reach much higher temperatures. This feature is essential when working with gases such as acetylene and propane, which require a reliable ignition source to ensure safe and effective operation.

While torch lighters can ignite flames for other purposes and may provide a continuous flame, their specific design and intended use make them particularly valuable in tasks that involve the manipulation of gases for heating or cutting metals. The other options refer to functions that, while related to flame production, do not accurately describe the primary application of a torch lighter in professional or practical settings.
