The only listing that says the wire is copper coated
YESWELDER ZY-GHM-DYYL-2-319, ER70S-6, 0.030 in, 10 lb
The only wire on this shelf whose listing states that it is copper coated — which is the property that decides whether it still feeds smoothly at the end of the spool.
Of the seven ER70S-6 wires on this shelf, this is the listing that explains what the classification means. The manganese and silicon in the wire are deoxidisers; carbon dioxide shielding releases oxygen in the arc; more deoxidiser means the wire tolerates straight CO2 and higher currents, which in turn means sheet can be welded hotter without burning through. That chain of reasoning appears on no other page here.
It is also the only listing to state that the wire is copper coated. On a steel MIG wire that is not a trivial detail: the copper flash reduces drag through the liner and carries the current into the wire at the contact tip, and poor coating is what makes a cheap spool feed badly and eat tips. Seven wires here share one classification and one of them mentions it.
The specification line at the end is unusually complete — 10 lb, 4.5 kg, 0.030 in, 0.8 mm — and both gas options are named. What is missing is a tensile figure, which one wire on this shelf publishes, and any basis for the claim to have “the highest combination of manganese and silicon deoxidizers”, which names nothing to be highest among. Its reference, ZY-GHM-DYYL-2-319, shares its prefix with a PGN wire on this shelf.
