AWS Welding Inspection and Testing Certification Practice Test

Which method is the only acceptable way to light oxy-fuel torches?

1. Match

2. Flint striker

3. Electric lighter

4. Striker

The correct answer is: Striker

The only acceptable way to light oxy-fuel torches is by using a striker. This method is preferred because it provides a safer and more controlled flame ignition compared to other methods. Strikers are designed to produce a spark without introducing a flame directly to the gas, which minimizes the risk of flashbacks or uncontrolled ignition that could occur with matches or other open-flame methods. Using a striker helps reduce the chance of igniting flammable materials in the vicinity and can be used effectively in settings where a clean and precise ignition source is necessary. Furthermore, a striker is less likely to cause accidental ignitions, making it the most reliable choice for welding and cutting applications where safety is of paramount importance. In contrast, matches and electric lighters have inherent risks; matches can ignite unintentionally and electric lighters may not provide a consistent spark in all conditions. While a flint striker is similar to the option of a striker, it may not encompass the broader category that the term "striker" refers to, which includes various design types specifically made for oxy-fuel applications.
