Using the welding brazing rodsI need to get the ali tube up to 400C and melt the rod on the surfaceI've researched loads but getting contradictory answersOne says propane is sufficient as long as the nozzle diameter is at least 3/4quot;Others are saying I will need mapp or acetylene.Please give me your advice and tell me about your experiences?p.s I tried using a propane/butane mix gas with a torch bought in BQ but the nozzle was only around 8mm and that didnt get the metal anywhere near hot enough.Thanks!Kelly
I use mapp gas , it will reach 1,000 deg I have rods that melt at 700 deg [alum]
