Reliable weld quality with Esab

Practical benefits

Smooth and consistent wire feeding: The copper coating ensures optimal gliding through the torch liner, helping you prevent wire feed disruptions during demanding jobs.
High tolerance for surface impurities: Formulated with manganese and silicon deoxidisers, it allows you to weld through light rust and mill scale cleanly.
Versatile structural steel welding: With a 1.2 mm diameter, you achieve strong joints on non-alloy and low-alloy steels using mixed shielding gas or pure CO2.

In a nutshell

The right choise for

With the Esab ok Autrod 12.51 solid MIG/MAG welding wire, you achieve strong and consistent welds on non-alloy and low-alloy structural steels. Its copper coating ensures smooth and stable wire feeding through the torch liner, reducing contact tip wear and keeping weld spatter to a minimum. Formulated with manganese and silicon deoxidisers, it welds cleanly through light rust and mill scale with excellent bead appearance. Featuring a 1.2 mm diameter on an 18 kg spool, this wire is ideal for heavy structural fabrication, pressure vessels, and repair jobs using either Ar/CO2 mixed gas or pure CO2 shielding.
