I use Oxy-Propane almost exclusively, and I must agree.  If I want to 
weld something with a torch I switch to the Acetylene.  "Nothing else 
welds worth spit."    :-)

	Heh... we just had this argument in rec.crafts.jewelry, only oriented
	to silver soldering/brazing.

	I like oxy-acet, but propane is also very nice.  The main problem is
	safety.  It really is not very safe to have a propane tank inside your
	home and in many places it is in fact illegal to do so.  Propane is
	heavier than air if I recall correctly, and tends to settle rather than
	dissipate the way, say, natural gas does.  So if you're a smoker and
	have a leak, you may blow yourself to kingdom come.

	However, technically, I really like natural gas and propane for soldering.
	Very clean and you don't have to be as expert with handling the flame so 
	it's notably more difficult to slag your work, which I've done a few
	times with oxy-acet.  This is very aggravating when you're working with
	fine gold pieces that took a LOT of work to finish only to find them lying
	in a half slagged heap on your soldering bench.

	Oh my.... seems I've gone "off" yet again...  sorry.  Please continue.
