After all the searching I've done I decided to ask a pipeliner buddy of mine if he knew of such a rod. He said "sure they're called 27P rods. Cantankerous rods to get used to due to the thin flux coating but work good once you get used to them. Particularly at starts, if you lift the rod slightly striking an arc the weld looks like moonbase 1. Gotta keep a very tight arc. Run on plates help alot for structural work."
So here it is: http://www.esab.ae/ae/en/products/index ... ode=410633

Very tempting for a video ain't it. You know its gonna eat away at you until you do.
