Minor Burner and foam?

[Veda's Beads]

Okay, I've looked around and can't find the answer to this question anywhere so here goes...
the other day a ran out of oxygen in the middle of a torch session and the flame went out, and then foam started bubbling out of the torch head so I tried to turn it off quickly and ended up turning the valve the wrong way and the foam sprayed all over everything from my torch to the wall. So my questions are: Why did this happen?
What can I do to keep it from happening again?
Is it safe to hook everything back up and try again?

Thank you.

Was there any odor to the foam? I've never EVER heard of this before.

It's possible that the foam may have been odorant gunk that had accumulated in the fuel gas line, but since you are using a minor, which also means you are using a regulator, it is unlikely that the odorant gunk was able to pass through the regulator.

Was the hose set previously used with a hot head or other fuel/air torch?

Hi Mike! The hoses haven't been used before hooking them up to my minor. It must be some really stupid thing I'm doing wrong though because I had foam spit from my HH too, which was what finally prompted the upgrade. So, two different torches, two types of gas, two different hoses, the only thing that didn't change was me - :(
I asked the guys at both local welding stores, one of them told me that the gas tank must have been tipped on it's side at some point (that was the mapp gas with the HH incident) but you can't accidently tip those short squat bbq size propane tanks. Anyway, thanks for your response, I'm going out to clean up and try again.

Yeah, I've never heard of that either! Weird.

The only time I had stinky yellow foam spray all over me was when I went to disconnect my hothead bulk fuel hose at the tank and had forgotten to bleed the line and leave the valve open at the torch. The pressure shot all that foamy odorant gunk all over me. Talk about greasy stink!

I can't imagine this happening with a minor through a regulator...I sure hope you figure out what the problem is!
