seems like you ought to be able, considering the working temps. With acetylene The Process is that you get a neutral flame, heat the metal to yellow or white hot, activate your cutting stream (lever that puts out a blast of extra o2) and cut your metal. The metal is actually burning away with the o2, and in a perfect world, O2 could take care of the whole deal once the reaction starts. In this world the heat from the acetylene/ MAPP is needed to maintain the reaction (oxidation). Keep the tip of the blue cone just in front of the surface to achieve the desired temp. Move at a slow pace or you will outrun your heat.
