I use this last blend for forge welding, (hammer and anvil and a coal fire).

Yeah, I witnessed it being done. Big amps 500+ and AC current but it layed down a bead of hard surface. Huge amounts of spatter but as the factory rep told me, spatter is fine if it also restricts wear. These were on the bottoms of buckets, welding large beads in a waffle pattern where the steel and slag they were moving would pack in to the waffles and work as abrasion resistant it's self.
