Yes and no. The difference has to do with overall heat mass, or size, of the object you want to heat up, as well as what is sinking the heat away. I can use a rosebud to heat up a three inch pipe and get the whole thing red hot, but I don't think I can make it white hot or melt any of it. The cutting tip can put out the same heat in a theoretical sense, but it's obviously more concentrated. It will heat a small part up better than a rosebud sometimes, but for a larger item you'll be there all day trying to get it red hot evenly because the temperature will be so much hotter under the torch and as soon as you move it away that small spot cooling down again, having its heat sucked away by the surrounding metal.
