Just for tacking alot without pecking all the time
If you are arc welding an have a lot of tacking and need to hold your steel in position. I grind a grove in my stinger that is about 15-20 degrees so i can chuck the stick back down towards my primary hand. Hold the stinger in your palm and the stick in your middle finger and thumb. Or whatever is comfortable for you. This gives me great grip on the stinger and stick and a free hand to hold piece to tack.
