What is the proper lighting device for an oxy-acetylene torch?

• A. Matches
• B. Lighter
• C. Electric lighter
• D. Flint operated spark making device

Answer: (D)

To light an oxy-acetylene torch safely, you want a spark-producing ignition device designed for welding. A flint-operated spark making device creates a brief, hot spark exactly at the torch tip as the gases are opened, so ignition happens only when you’re ready. This minimizes the risk of gas accumulating or a flashback into the torch or hoses.

Using an open flame from matches or a lighter can ignite the gas prematurely or unpredictably, which is unsafe in the torch setup. An electric lighter can be unreliable in a workshop environment and still relies on an external flame or spark in some designs. The spark-producing tool avoids these issues and provides controlled ignition at the torch tip.
