    Its the machine, most 7018 is a DC+ rod. They do make it special for AC, but most of it is for DC, thats the reason.

    AC vs DC stick welding

    i(we) own an AC 225 lincoln buzz box and i have and use mainyl four types of rods, 6013 1/8in., 7018 1/8in., 6011 1/8in. and 5/32in. 6011. now my question is that in most welding books it says 7018 is smooth to run but when i run it is very rough and ,well not spattery but not very smooth, also i have used a lincoln ranger 250 dc stick with the same rods and its nice and smooth, is this just the difference in current or is it the brand of rods i run(7018 is hobart, 6013 and 6011 is lincoln) the lincoln rods tend to run smoother than the hobart rods... is this just operater error, i know arc length could be a factor but ive tried shorter and longer lengths but there is no change...
