ED030392 - Lincoln Metalshield MC-6 .045 Metal Core Wire 33lb Spool

Boost Productivity with Metalshield MC-6

For welders who demand speed without the mess, Lincoln Electric's Metalshield® MC-6® is the metal-core wire that delivers. If you are tired of battling excessive spatter or struggling to maintain a stable arc at high travel speeds, this .045-inch wire is designed to solve those exact headaches. It is built for the modern fabrication shop where efficiency is king. Whether you are running a manual gun or overseeing a robotic cell, the MC-6 allows you to lay down beads faster than traditional solid wires, helping you meet tight deadlines and production quotas with ease.

The first thing you will notice is the smooth, buttery arc. Metalshield MC-6 offers exceptional wetting action, meaning the puddle flows out effortlessly to the edges of the weld joint. This creates a flat, professional-looking bead profile that requires little to no grinding. Even if you are welding over steel that isn't perfectly clean, the deoxidizing agents in the core help burn through light rust and mill scale, saving you prep time. Plus, with its "fast-follow" capability, you can move quickly along the joint without the puddle skipping or breaking continuity, which is a game-changer for long fillet welds.

Cleanup time is dead time, and Lincoln knows that. That is why MC-6 is engineered for minimal spatter. Less spatter means you spend less time scraping BBs off your workpiece and more time welding. It also means your gas nozzles and contact tips stay cleaner for longer, reducing downtime for consumables maintenance. The H4 low-hydrogen rating is an added bonus, giving you peace of mind that your welds are strong and resistant to cracking, even in demanding applications.

This 33 lb spool is the perfect size for standard shop wire feeders, giving you plenty of run time between changeovers. If you are looking to upgrade your MIG process from solid wire to something that offers higher deposition rates and faster travel speeds, the Metalshield MC-6 is the upgrade you need. It bridges gaps well, runs smooth, and leaves a finish you can be proud of.
