Brazing With Propane Blowtorch
Clean the metal you plan to braze.
Brazing with propane blowtorch. Place the metal on a fire safe work surface. See flame temperatures below. Arrange the metal you plan to braze so that it cannot move. Takes burners 4103 4104 and 4105.
The autotorch brazing system gives extra performance on propane at 4 bar pressure. Use sandpaper to remove oxidation. There are different gases available which you can use map gas is a slightly higher temperature gas than propane although we are talking 2100c instead of 1900c so i am not sure how much difference that will make. Heat the two metals.
The special burners operate at higher pressures and can punch more heat into the workpiece and thereby achieve higher workpiece temperatures.
