They are not 7018AC.. they are not the optimized flux for AC.. and like every one says, they are too big for ordinary use.. Not that you couldn't run them on about 200 amps. but your welders duty cycle is such that you don't want to do that long. So long story short, really not a good rod for the machine. 6011, good penetrator, and good for less than the cleanest metal or 7018AC good strength, and optimized for AC or 7014, very easy to run and very pretty welds, but not quite as strong. either 3/32 or 1/8.
