Torch burns too much oxygen very expensive to operate.
Brazing sheet metal with mapp gas.
Like is mentioned they are good for welding or brazing small steel items.
Position the metal as desired.
I also have the small oxy propane mapp gas torched too.
Others rely on air to provide oxygen to the flame.
Brazing is distinguished from welding because it uses an intermediary material usually a copper zinc alloy to join the two metal pieces rather than melting the pieces.
Some mapp torches use a separate oxygen cylinder.
Used it to weld an exhaust bracket good for those types of repairs on the trail since it can secured in a small space.
If you lean out the oxygen to conserve it the mapp gas burns dirty does not get hot enough and produces large amounts of soot that sticks to your metal.
The oxygen tank does not last long at all.
The 7 minute burn time for an disposable oxygen bottle goes faster than you think.
Light the welding torch and adjust the flame.
Touch the flame to the work pieces and move in a small circle to melt the material at the weld zone.

You can t braze dirty sooty material.
If needed use clamps to secure the pieces in position.
Heat sources include a propane or mapp gas a turbo tip.
Brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal.
Apply the brazing rod to the joint while continuing to heat the metal surfaces.
Heat the joint where the two pieces of metal will meet until the joint glows.
