Cutting with ultra-thermic electrodes is a technique frequently used for cutting under water. Its principle is to create an electric arc and simultaneously send a jet of oxygen through the electrode which then allows the cutting of the piece. In order to achieve maximum efficiency, manufacturers of all kinds advocate the use of oxygen with a purity of at least 99.5% and specify that otherwise the user can expect a loss of performance equal to 25% per less percent of oxygen. Clearly this would mean that it would no longer be possible to cut with oxygen whose purity would be equal to or less than 95%.
But is this really true, because some claim to dilute oxygen with air and thus cut with a much lower percentage that can even reach 60% purity.
This seems very little, but maybe after all that remains possible.
So I realized a small cutting test whose results can be seen here on this video :
