I've been practicing a lot with 3/32 7018 rods, and i've improved a lot, but sometimes I notice that there are holes in the welds, sometimes in the beginning, sometimes in the end and sometimes randomly on the sides of the weld. Also, I'm using DC with about 125-130 volts and I can only use 3/4's of the rod before it gets red hot and burns way to fast...the welder is run on a 50amp if that has anything to do with it. I'm also wondering if 3/32 is a good size to use? I can't seem to get any good pictures but i'll go try one more time. Thanks for any help.
