Hi Mona, et al, The pressure of natural gas at the house is very low
because furnaces and water heaters require that. I’ve used NG (with
the low pressure) and compressed Oxygen for years. NO problem with
high enough heat to solder, fuse, melt (darnit), etc. (I don’t
cast, so can’t comment on that.) If working on a large sterling
piece, I build a little enclosure around it (like an oven) to hold
the heat and use a larger tip.
I know this thread has gone around many times, but there are no
stupid questions and I learn each time.

Such a good sound to sleep by.
