I have a large propane bottle that I anneal or heat metals with, it has a bullfinch standard torch, I need a torch to silver solder or braze with, have a couple of Oxyturbo kits but the cost of bottles is crazy now that I have retired from working 6 years ! been looking at bullfinch 404 brazing torch kit (4100 torch) that is about £110 cost, there is also Sievert pro 86 kit, a bit cheaper, wondering what is best, also don't understand LPG gas whats all that about ? any advice welcome please
thank you
Dave
