1251086700 - ESAB OK Autrod 12.51 ER70S-6 MIG Wire .030 15kg Spool

Smooth Feeding Wire for Tough Jobs

If you are looking for a MIG wire that just runs right, the ESAB OK Autrod 12.51 is the spool you want on your machine. We all know the frustration of dealing with cheap wire that sputters, burns back to the tip, or birds-nests in the drive rolls. ESAB has engineered this .030" wire to eliminate those headaches. The high-quality copper coating isn't just for looks—it helps the wire slide smoothly through your liner and make solid electrical contact every time, giving you a buttery smooth arc that sounds like frying bacon.

Real-world welding isn't always on perfectly clean, shiny metal. That's where the "S-6" classification of this wire shines. It is packed with deoxidizers that help eat through light rust, mill scale, and dirt that you might find on structural steel or farm equipment repairs. Instead of trapping bubbles and causing porosity, this wire helps float those impurities to the surface, leaving you with a solid, clean bead. It wets out nicely at the toes, meaning you get a flatter bead profile and less grinding if you are painting over it later.

This 15kg (33lb) spool is the standard size for industrial wire feeders and shop carts, giving you plenty of arc time between changeovers. Whether you are fabricating a new trailer, fixing heavy equipment, or doing general shop fabrication, the OK Autrod 12.51 delivers consistent results. It works great with C25 gas (Argon/CO2 mix) for a clean spray or short circuit transfer, but it also runs reliably on straight CO2 if you need that extra penetration. Load it up, set your tension, and get to work with confidence.
