    Palladium really likes to absorb hydrogen, you will likely cause
    yourself some porosity problems if there is a significant amount of
    palladium present. Use oxy/propane it will melt all the above metals
    without too much problem from a gas absorption standpoint. How do
    you plan to apply / keep the argon over the melt if you are torch
    melting?
