There is another trick that I like to use. Place a flat washer onto the broken stud/bolt. It will help if the ID of the washer is less than the size of the bolt. Use your migwelder to held the washer onto the bolt. The washer contains the weld, so the bolt is not welded to the block/head. Then weld a nut to the washer. This can be done on the inside of the nut, or on the outside down the bottom. Then put a spanner on the nut, and remove the thread. If it snaps off, do it all again. It will come out. The welder also helps by heating everything up. You can generally apply more torque this way when compared to using easyouts.
