Just to add to the welding tricks... I have placed a small nut on the broken bolt/stud/tap and welded a puddle down the hole to the offending stuck thing. Even had luck with stuff broken off below grade. With a MIG, make sure the wire hits the stud first and fill up the nut. While red hot, hit it with a wax candle. Best if you get some fire. The hot wax gets drawn in to the threads. Wait a minute or two and wind it out. We made a few dollars on broken stud removals this way. Good luck !
