The handle isn't, to me, "sheet metal" - it is a structural part, however thin, but still structural. Maybe that would have been a better rod - at least for building the holes back up?

    I can't remember the last time I used a 6013 rod - I'm sure I did on a farm somewhere 6-10 years ago. If it doesn't penetrate like 6011 or 6010 - will it get through slag? That was one of the biggest pains with the 7014 - the slag it produced blocked the next weld. If 6013 can get through its thinner slag then the slag inclusion problem of the 7014 would be eliminated. Of course, best practice is to clean the slag. Inside of a hole and crevasse between two welds you can only get it so clean though...
    Of this your "thinking" then perhaps you should compare the weld properties of 6013 and 7014. Farmer rod vs "structural rod".

    6013 is not my favorite rod, however I do use it.

    Most structural tube is rolled blossoms from sheet metal.

    Most ag work I would use 7014 good weld, med pen and cost good. But even that for some types steel I would need a different rod.

    6013 typically is used for light gauge.

    Structural steel I first check the specs to see what engineer wants. If not given see what welding hand book spec's out for type of steel.

    I never wing it when come to any structural steel. That way is in California and other states copy what California does.

    7014 is not a structural rod but far better than 6013.

    Here is what Hobart said about 6013.
    General purpose fabrication, machine parts, metal buildings and structures, shaft build-up.

    The three types rod for most my work and specs (6011, 6013 and 7018)

    For plate 6011 was only used for first pass then 7018.
    6013 was used for gauge and galvanized gauge.

    Using the guide that the rod manufacturer

    6013 can be pretty. My son did this in his welding class. Smooth as a baby's behind. He said is was so easy and quick. Quite a concave bead but sealed things up nicely.

    Have you tried 7014 on AC or DCEN? Adding yet another variable or two makes for good fun.

    Oh, if you ever get a chance, try some 1109 rod. Good stuff from what I hear.

    Is that the old AIRCO/Murex stuff now made by Lincoln? I know a guy who swears by it - he won't use Lincoln's other version.

    Yessir, that's the stuff. It's made for AC welders with low open circuit voltage but is awesome on DC too. Makes for a nice soft arc with light slag at low amperages.

    Unfortunately it seems to be only available in 50# boxes. I've used it for years on thin irrigation repairs. The brown Lincoln Fleetweld stuff is garbage in my opinion.

    I keep some 1/16 6013 around for super thin stuff like that. Not something to run every day but it has come in handy more than twice.
