I'm setting up shop again, and there's an endle$$ list of things to be done
and got.
One of them is ga$ cylinder$.
And then, I observed the obvious. I have several barbecue bottles. So,
thinks me, why not use them for cutting? If I don't have to buy an
acetylene cylinder, I can use the money somewhere else, plus, propane
filling stations are a lot closer than the AirGas store.
Compared to acetylene, what's the bottom line? I know I would have to go
buy some new tips, but I just bought a used rig with one tip, so it's not
like replacing them all.
Most of my cutting would be up to 3/8", and a lot of that less. I never say
never, and never know when someone will bring in some half inch broken piece
of machinery that needs gouged out and fixed.
What's the pros and cons of propane vs. acetylene? Propane's limits? Its
downside?
Advice, experience and opinions welcome.

I have no first-hand knowledge but I have observed that a lot of the scrap
yards are using propane for cutting up light and heavy scrap. One owner told
me it worked nearly as well and was a lot cheaper.

Please log in for more thread options The main ingredient for gas cutting is oxygen, which is not available
at the nearby hardware store. Anyway, whenever I use my plasma cutter,
I feel that I am in a cutting heaven, and do not feel any need for a
gas cutting setup. Mine is a Hypertherm Max100.

We used LPG for cutting years ago in Thailand. As I remember it needed
a larger tip then acetylene as LPG produces fewer BTU's but other then
that it works well.
One thing, you can't weld with it. For some reason at about the time
the metal starts to melt the torch goes out with a very loud bang.

I consider someone seeing something in action as first-hand knowledge.
