Hi Bob,
I don't think you would want to use 200 watts to solder smd's with, 15 watts is more than enough. I have Weller station and my dial is calibrated in temp not watts. I keep it about 600 degress unless I'm trying to solder to a large ground plane. I like to have a iron a little on the hot side it puts less stress on the parts by flowing solder faster and getting off quicker than to slowely heat things up. Check your iron I can't believe it is 200 watts.
