    Cheap Welding for Punks

    Propane is great for cutting. There is a good reason that propane is not used industry wide for welding. Acetylene's flame is not only hotter, but a slightly carburising flame makes for a high quality weld due to the molecular properties of acetylene. You could weld with propane, but with much less quality.
