If there not welded on, I would remove and repair or replace. I would double check to see if they're actually welded on. If they're welded on, place a block of wood, under the straight portion of the jack pad, and lower the jack, putting pressure on the wood. Then take a hammer and beat the bent part downward. I wouldn't heat it!
