1 pointFor small jobs it can work quite well - just be sure you 'tin' (heat & apply a surface coat of the braising material) the surfaces prior to joining, it will make for a more complete join. Just like solder & traditional braising, the join is more complete that way. I used it to do IC piping before I bought the TIG, and for large areas like that it was a royal PITA - I would not recommend it for that at all. Small OD work is not bad.
