Id like to know the differences in using these two fuels for normal
around the farm cutting and brazing.

I understand that propylene is safer, has more in the tank, is
cheaper..and thats all I know.

Ive got an old S/V 100 torch handle and various cutting heads and
brazing tips, as well as an old Union Carbide cutting torch.

I have to change the cutting tips, correct? What about the existing
brazing tips?


I haven't done cutting, but I did not have to change anything for brazing.

How much does a tank of propylene cost versus acetylene?


I have a tank about the size of a small propane tank - I forget the
description,
but it is maybe 15 Lbs or so, about 2.5 gallon size, I think. It has lasted
years, and I suspect there are a few more years left in it. It is
supposed to cost
$10 - 15 for a refill.

Is there an issue with my hoses?

Regulators? Can a acetylene regulator be used for propylene?


I'm sure of that, as the guy at the local gas supplier refitted my
regulators
for his tanks and said everything was OK.
