A good combination is to have flashback arrestors at the regulators and check valves at the torch end.

The check valves are nice because they don't add a lot of bulk at the torch end.


And these are the arrestors.

When you inspect torches, keep an eye out for indications of internal fire damage such as heat discoloration.

This now-much-shorter Victor mixer left parts of itself in the tube when it melted. I guess the Smith and Airco designers have a point. Tip-mix torches don't do this:

good post...this is good to know...i always lite my torch with mixed gas so it does have all the black smoke.

I would recommend investing in a newer torch with built-in flashback arrestors and reverse flow check valves. It is too easy to get in a hurry and not take the time to put these in the line to the regulators separately.

under what circumstances would anyone use acetylene over 15lbs? i find 10 lbs works fine for everything from sheet metal to 3" plate by changing the cutting tip to the correct size.

This one provides an excellent visual of what takes place during those undesireable conditions.

Excellent video Duane

Just reposted it Steve. Someone else did awhile back and I think the entire video series on proper setup and use should be a must watch for newbe OA torch users as well as a refresher for seasoned operators.

I can watch stuff like that all day long.

I've been very fortunate & never had probs with my OA equipment.

Good info!

Great thread with great info!.. The YouTube was nice too! Showing what can happen during a "flashback''!

How many on here have the flashback arrestors on their O&A setup ?

Thanks!
