    I am wondering what the advantage you believe you will gain by using
    hydrogen. I have used it for casting gold and sterling and my
    experience I can use acetylene for casting, and acetylene or propane
    for repair and fabrication. I went to hydrogen because of some
    opinions I read about acetylene being a dirty gas and was responsible
    for porosity problems in castings, but I was not having problems. I
    just stopped using it, there was no practical reason to use it.
    There were no results I could not get using propane or acetylene. If
    you have not had experience using hydrogen, it might be quite
    different in reality than what you imagine it to be. It is in no way
    similar to a hydrogen water torch. I have a regulator I do not use in
    perfect shape I would be glad to sell it. Contact me offline if you
    are interested.
