Great advice! In my early 20’s I worked for a shipping company in Seattle that repaired their own containers. There were a couple crane operators that kept us busy. I did quite a bit of grinding. One of the old welders had one of his helmets permanently hanging on the break room wall. It had half of a wheel lodged in it from a blow out. If he wasn’t wearing it, he’d still have pieces of that disc affixed to his cheek bone. Use face shield for sure & always keep your face out of the line of fire! I let my 16yo son grind, but I won’t let him cut until I get a good, safe opportunity to show him how to use one of those discs.
