One other welding safety issue is protection from the arc flash. I used to be a welding supervisor. The old timers would completely cover their bare skin so they would not get sunburn. They even buttoned their shirt collars all the way to the top to keep from getting burned on the neck. I always see pictures of amateur welders welding without gloves, or tack welding without a welding hood. The old time welders would not even think about using a auto-darkening welding lens because of the split second your eyes get the arc flash. A lot of people think an arc burn is no big deal and will go away in a few days. It will, but what about years down the road and skin cancer? Just some food for thought.
