Try to look for a Vladof or Torgue automatic rifle if you're on the first playthrough. I find it helps either to keep Sledge peppered with bullets, or to simply continue to pound at him with high damage output. Also, you'll want to have done the Crystal Harvest at the Lost Cave to get a Shock Artifact, this helps you use your action skill to take out his relatively powerful shield. Apply this principle to your weapon as well, try to use a Shock weapon to take out his shield before switching back to a harder hitting gun to kill him. Also, make use of Grenades, I find using Transfusions from behind cover works no matter what your class because Sledge and his Shotgun/Hammer combo can really deal out massive hurt in short periods of time.
