QUOTE(sixaddict @ May 3 2023, 03:27 PM)  Help. Two STUCK studs. Used heat, special Collette tool, impact wrench and tapping. 3 days still no luck. Ideas?.. What are the studs in? If they are head studs I've always found it hard to put enough heat on a head stud. I mean the head is designed to dissipate heat right? I've only had luck with acetylene or welding a nut right onto the stud. If you are using a MIG setup for sheet metal with like 0.023 wire you need to really crank it up. Do it along with copious amounts of penetrating oil. Have plenty of ventilation and be prepared for some fires. Plan on a mess. Good Luck Kelly |

Nothing would budge them Until my neighbor taught me a trick TIG machine No filler or tungsten Hold the torch on the top of the stud until the stud glows red All of the heat is concentrated on the stud They all came out after this. Easily |

Thanks for the great TIG tip |
