A guy at work gave me about 30# of fairly new 1/8 dia. 6010 electrodes. I have never used them before, and only have experience with 6013, and 7018, 7024, and limited 11018 experience. I've been told they are difficult to work with, but I recently started fabricating some equipment to use in strongman competitions like you may have seen on ESPN. I use a lot of sch. 80 pipe, and 1/4" wall tubing, and the 6013s have alwys been sufficient. However, I buy them in the small cans from Home Depot so they aren't wet, and my understanding is that the 6010s can live in my shed in a storage tube, and I don't have to worry about moisture content in the coating. Sorry for the long post, but I can't look this gift horse in the mouth.
