Bernzomatic calls this a "Soldering and Brazing Torch Head", but don't believe the brazing part. Even with map-pro, it doesn't really get hot enough to braze with brass rod. It solders just fine, though, with an adjustable flame and a precise cone. I paid $69 at Lowes, it's presently $49 "on sale", which I take to mean clearance. Give me $20 and you can have a mostly full cylinder of gas to go with it.
