I am welding some .125 cold steel and all my welds are looking like popcorn. It seems nice untill I hammer the slag off and then it looks nasty like it caved in or something. My straight welds come out just fine, only having this problem on a 90 degree weld. Currently I'm using 6013 but 7018 and 6011 are doing the same thing. I am running about 80 - 90 amps AC.
