    With oxygen and PROPANE or natural gas, I think a number six tip
    isn't unreasonable.  With acetylene, you're right, it's perhaps
    overkill.   But a #4 is pretty small with propane, and getting a #3 to
    even light, and stay lit, with propane, can be a good trick in itself
    sometimes.  With oxy/acetylene, of course, it's just fine.  but with
    propane, about all you'll solder with a #3 is small wire work...  Of
    course, all this depends as well on the size bezel being soldered.  If
    it's a 3mm bezel going onto thin sheet, that's a whole different
    problem that if it's an 18x13 bezel..
