How big a brazing torch do I need?
I know this is a bit of a 'how long is a piece of string' question but
I need some sort of way of working out what gas brazing torch I need to do something. I want to fix a small crack in a transaxle casing from a mower, the casing is maybe 8" in diameter and made of 1/8" thick (or a little thicker) aluminium. I have a "laser 4707" aluminium brazing kit and my trial on a bit of 1/8" thick aluminium angle worked pretty well (I'm used to soldering and welding so something sort of half-way wasn't too difficult). I did that with a Bernzomatic TS2000 torch which I bought a long while ago for odd plumbing jobs. However the Bernzomatic TS2000 won't get the transaxle casing hot enough, it's fairly close but not enough to get the material to 'tin' nicely. So, would a bigger/better torch which uses the same gas canisters as the TS2000 be enough. The Bernzomatic site seems to suggest that the TS4000 (which Screwfix sell - https://www.screwfix.com/p/bernzomat...ng-torch/71976) is quite a lot beefier than the TS2000 and it can use the MAPP gas bottles which are also hotter I believe. -- Chris Green · |
