jayimim said:I did check out the torches, I found that the acetylene turbotorch like the mapp gas turbotorch that have the quick release tips have color coded o-rings, acetylene is red. Mapp gas and lp have blue. I have been told the acetylene is much hotter. Both setups utilize atmospheric air.
And possibly other related gasses, depending on where you are located. Even in the US, our "propane" is only around 90% propane, the remaining 10% usually being a combination of butane and propylene. The composition of "LPG" in other countries varies depending on pricing, availability, and climate, with higher butane content in warmer regions and propane in cold areas.saadat68 said:Hi
If I buy a oxy-propane torch for melting silver and gold, Can I use it for lpg gas and oxygen?
(As you know lpg is a mix of propane and butane)

Be sure your gauges and torch are designed for the gas you are using and you shouldn't have any problems.

I've never tried, so I don't know. Give it a try and let us know.saadat68 said:in some months in my country, lpg is 15% propane and 85% butane. Can I melt silver and gold with this mix without problem?
