When mixed with oxygen, propane does just fine (and is preferred by some professional frame builders) . Both oxy-propane and oxy-acetylene are well above 5000 degrees, with only about 4oo degrees separating them. Air-propane, on the other hand, (i.e. BERNZOMATIC) produces less heat and is not suitable for frame work.
