So the Camera Guy broke the handle off of his cast iron skillet. I have repaired several different pieces of cast iron throughout my welding career using a different approach than most. I was taught this method by my old welding instructor in high school and have used it on many cast iron repairs and have never had any issues.
If you go into any welding shop, you will no doubt find several different types of grinders.The right angle grinder is used to cut, grind, blend, buff and clean metal. Roughly 80% of a welders time is spent prepping the material, and there's no doubt in my mind that the grinder is used the majority of the time during the preparation of the work.
