Yup, that is pretty much right. A lot of people don't stick (SMAW or ARC) weld and thinks it's old school and not needed. To tell you the truth, I would rather stick weld my frame than MIG. But yes you need to know how to weld with a stick welder like when to whip or stack the dimes with what kind of rod, when to zig zag, under cut, roll over, what rod to use, etc. 7018 for your root pass and probably 6010 for your filler or the other way around. Just all depends. You cannot do the whip motion (meaning go farward and dig out your crater and come backwards real fast and fill in the previous crater with metal) with certain rods like the 7018 because you will trap slag but with 6010 rods you can do that. I do not trust welding the thickest metal my welder can weld at because it's struggling to weld at that base metal thickness and just not trustworthy IMO. But enough said from me, I am sure you get the point and we probably scared you enough as it is.
