## Questions & Answers

**Q: Is flashback arrestor needed on both regulator and torch end**
A: I haven’t ever seen a suggestion for having both ends having an arrestor attached. It seems redundant to do that to me. It seems having the arrestor at the torch end is the safest way. However I don’t claim to be an expert.
