ED033908 - Lincoln Metalshield MC-90 .052 Metal Core Wire 500lb Drum

Experience Superior Arc Stability and Speed

For welders who demand both performance and ease of use, the Lincoln Electric Metalshield® MC®-90 offers an exceptional welding experience. This .052-inch metal-cored wire is formulated to bridge the gap between the cleanliness of solid wire and the speed of flux-cored wire. When you strike an arc with MC-90, you will immediately notice the smooth, stable transfer and the wide, fluid puddle that wets out effortlessly at the toes. This superior wetting action helps eliminate cold lap and undercutting, common issues when welding at higher travel speeds.

One of the standout features of this wire is its ability to handle mill scale and minor surface contaminants better than solid wire, thanks to the deoxidizers in the core. This means less prep time grinding steel and more time welding. The 90,000 psi tensile strength ensures that your welds are not just good-looking but incredibly strong, suitable for critical repairs and heavy-duty fabrication on high-strength steels. Unlike flux-cored wires that leave a heavy slag covering, Metalshield MC-90 leaves only small islands of slag, making inter-pass cleaning quick and easy with just a wire brush.

Packaged in a massive 500lb drum, this wire is perfect for shop environments where you want to set it and forget it. You won't be stopping every few hours to swap out a 33lb spool, allowing you to maintain your rhythm and focus on laying down perfect beads. Whether you are welding heavy machinery parts or structural components, the consistent feeding and forgiving arc of the MC-90 will help you produce high-quality welds with less fatigue and frustration. It runs best on DCEP polarity with an Argon/CO2 gas mix, giving you that classic "hissing" spray transfer sound that every welder loves to hear.
