Default Propane torches

ups.com...
I could weld once - about 50 years ago - but have lost the art. I now
need to do some brazing, but cant justify expensive kit.

Here in the UK there a lot of plumbers torches, and you have to be
careful about getting the right one for brazing. MAPP gas is OK
apparently, but costs an arm and a leg, so I want to stick to propane.

It appears that propane torches running at about 4 bar get hot enough
without an air supply. Does any one know if this is correct please?
What are the respectable makes? Rothenberger seems to be around a lot.
What about Silverline or Bullfinch??


I do small brazing jobs with a "swirl-torch" - it has a vane-shaped gizmo
just after the orifice that creates a vortex and it is hot enough with
regular propane, at the pressure it come out of a small bottle.

The bottle gets cold quickly though, and does not last long. It's for small
parts only...
