When there is only one pipe which feeds the torch, the re-mixing is done directly at the exit of the electrolyte, like the "HHO" no separation of gases.
See paragraph https://en.wikipedia.org/wiki/Oxyhydrog ... _and_fraud , deleted on the French Wikipedia, probably tired of correcting the insertions of the clever little ones who took the opportunity to try to give credibility to the fallacious trade in HHO.

what interest to make experiments, whatever they are? Otherwise advance the schmilblick!

Proof that you express yourself without having consulted the whole subject, except the point of view of those who claim that the rabid dog to slaughter him.
Still provocative? :( and its nonsense! You who are so smart: what is the minimum temperature of a blowtorch capable of welding a rod on refractory brick without, at the same time, burning the skin?

It will depend on the melting temperature of the metal of the rod, it can range from less than 200 ° to more than 1000.
Melt a little metal on the surface so that it matches the crevices of the brick, then weld the rod on this pile. Nothing extraordinary, it's easier to use a mortar.
Just do not touch where it burns for the skin, I do not see where you are coming from?

the fusion of a welding rod at 200 °, it's a miracle then!

should i laugh? Did you examine the subject closely as proposed or do you have such a ridiculous opinion for each subject examined? But probably you have never welded a refractory material!
Just don't touch where it burns for the skin,
Elementary my dear Watson! Except that it is, in the demonstration, a voluntary passage on the skin to demonstrate that this type of torch does not burn it, while it also melts metal (a chouia more than 200 °)
I do not see where you are coming from?
To consult the subject carefully before having an a priori opinion on it.

Soft solder with tin requires a melting temperature of around 200 ° C. Descends to 144 ° in jewelry.

except that if you had followed the subject well on Brown, it is not about tin soldering. You will find on youtube, for example, these examples of heaters and if you manage to weld two stainless steel plates with a tin solder, it is that you are balèze, to melt a head of bolt, to pass your hand in the flame, etc ... it is that you are very, very balèze!

You-tube of course, You have an answer to everything
the video has the advantage, on an assumption, of being concrete and reproducible and that puts the criticism of Wikipedia in a cantilever.

Better to have an answer to everything than a solution to nothing : Lol:

On the video, the flow is clearly insufficient to make a solder :?

Quite cap'taine, not a specialist in this field, but I saw that at first glance and the preparation of the parts seems really sloppy! It is scary. Honestly I would never have posted such a video.
