6010-5P is a DC rev polarity rod and a root pass rod .
6013 is a mild steel all position and general purpose weld but has a heavy flux cover after welding with medium to low penetration , not real good on dirty or old metal with rust.
6011 will give a deeper penetration with less amps needs and a weld easily cleaned for multi-pass welding, less prep and some dirty or rusty metal can be joined .
7014 is not a true low hydrogen rod but gives a weld much like 6013 with higher tinsel strength 7024 is a drag rod with heavy flux coating for flat work where arc is maintained with flux in contact with work so no gap is needed to be maintained by the welder. Cosmetic good looking weld with low penetration
7018-AC or 7018 is preferred by many as it has a flux that is easily removed and gives a sound high strength weld and has a good appearance visually. A clean work surface is needed
Welding is practice, practice, practice. good prep and proper heat
