The nut has seized and locked onto this $20K hydraulic cylinder rod! We’re going to use carbon air arc gouging to try and remove the nut and save the cylinder rod. This is a bucket cylinder rod off a Hitachi EX1200 mining excavator. In this video we show the step by step process how to gouge off the seized nut using carbon air arc gouging. Stay tuned for the next video where we need to machine up a new nut and we will be machining new threads onto the cylinder rod.
