What tool is recommended for striking the oxyacetylene torch?

The recommended tool for striking the oxyacetylene torch is a spark lighter, also known as a spark igniter. This tool is specifically designed to produce a spark that ignites the gas flowing from the torch. Spark lighters are advantageous because they offer a controlled method of ignition, reducing the risk of backfire and providing a safer way to light the torch compared to other methods.

A flint spark igniter is generally reliable for creating a spark, but it may not be as effective as specifically designed spark lighters that produce a more consistent and stronger spark. Using an old matchstick can be unsafe and impractical, as matches might not ignite the gas effectively or may expose the user to flame hazards. An electric starter, while useful in some contexts, may not be as common or practical for oxyacetylene torches, which often use a manual method for ignition.

Therefore, the spark lighter stands out as the most suitable and safe choice for this task.
