switching from acetylene to propane?

[Turbo]

Speaking from experience here.
First of all using compressed air and propane will not get anywhere near as hot as oxygen propane. Bare in mind air is made up of oxygen, nitrogen, Argon,.co2 etc. All these extra gasses lower the flame temp.
The town gas braziers were the FlameFast brazing hearths. They're ok but still don't get nowhere near as hot as oxy/propane.
You can't weld with oxy propane bur you can do everything else. I use all my oxy acetylene gear and just use an adjustable propane reg. I use a BOC saffire torch with the acetylene tips and they light just fine and are very controllable.
I also have some rose bud tips on an extension for some serious heat on big stuff.

Propolene or Mapp gas is a waste of money because you still can't weld with it either so may aswell use propane which is a hell of a lot cheaper

This is running on oxy propane

Those rosebud heating tips are a serious bit of kit! That looks like a 4H or 5H.

I have a 3H and the roar of the flame on full chat is scary. I think I have a 5H too but it is a different fitting to my swan neck.

Its actually only a 3H but gets nice and toasty!

ok that sounds like a start and do Acetylene regs fit propane bottles

yep

A fan won;t make the pressure you need, a compressor would

no idea how well it would work... at school I'm pretty sure we used mains gas and compressed air too

I might be able to push 5 psi plus , with the fan idea so might easily get the flow required as well The fan outlet is a lot more powerful than the 45 litres Titan vacuum cleaner's air outlet

Your picture speaks a thousand word ..thank you .

I have a tar burner lance for lots of heat , As I've only had it a short while I haven't tried silicone brass brazing with it incase it blows the heated bits apart with the force of the flame . However now I have several unused inch thick 50mmx 120mm fire bricks I think I'll have a play very soon .

We did, used a gas & air torch too. Wouldn’t be allowed in schools today, along with a coke forge, Health & Safety!

My daughter has been using a gas and air torch at school to make things for her GCSE this week

Don't assume everything has been banned because of the imaginary health and safety police

propane bottles are left hand thread and needs a propane reg, left hand threads have slits cut into the side of the nuts for reference.

"over here" they have changed to a large outside thread (looks like acme) and it's right handed
for all the idiots.
