Thanks for the links, have some brazing to do but unfortunately the hottest heat source I have is mapp gas and as the components are quite heavy cant get them hot enough to get braize to work properly so will need something hotter can anyone tell me what sort of torches and hoses/ regulators I would need
If you are thinking of using Albee cylinders, they come with built in regulators, so you will only need hoses and a torch. Appears from the Hobbyweld website that some of their cylinders don't have built in regulators., so they will have the standard 5/8 BSP 'bullnose' connection for regulators -right hand thread on the Oxygen and Left hand on the acetylene. Regulators are available in 1 or 2 stage options. The line pressure, and therefore the flame will be easier to adjust and maintain with 2 stage regs, but of course they are a bit more expensive than the singles.
With either the Albee or Hobbyweld options, you will need flashback arrestors -these are fitted between the regulator output and the hose -they're just visible in the photo I put up. Welding hoses come with 3/8" BSP threaded couplings for the regulator end, and either 1/4" or 3/8" BSP for the torch end depending on whether you have a 'lightweight' or 'standard' welding torch.
