I'm a welder. Spray Arc mig-high speed, high voltage, blah blah blah... I work for John Deere-Hitachi Construction Machinery Corporation. We manufacturer light and medium duty excavators from the ground up, everything from the 12ton to the 35ton. I am currently on medical leave for a dislocated foot, shattered fibula, broken tibia, screws, plate--the whole nine. It happened Oct 21 of last year, and I'm just beginning to walk again. Been a long hard road...
