I don't know what pressures you set the tanks to, but wouldn't propane use up an oxygen tank faster than acetylene would? And if so, would the extra money spent on oxygen not negate the saving of using propane rather than acetylene?How mutch will you be useing it / what size bottles do you need. Also if your just heating / cutting have you considered oxy / propane.

Yes you use more oxy with propane but it works out cheeper in the long run, don't forget you only get about 30psi in an acetylene bottle.
Have you looked at oxy/propylene Adams gas do rent free propylene
I think hydrogen is used for underwater welding where the pressure would cause acetylene to polymerise, it's probably very expensive and more dangerous though.there doesn't appear to be any real alternative to acetylene for that.

I haven't tried it myself but it is sold as welding/brazing gas.Then I think I'll happily stand by my statement that 'there doesn't appear to be any real alternative to acetylene'
