87107 - Böhler Diamondspark Guard 420 MC .052 Metal Core Wire 16kg

Experience Smooth Feeding and High Deposition

Upgrade your welding game with the Böhler Diamondspark Guard 420 MC. This .052" metal-cored wire is a dream to run, offering the best of both worlds: the high deposition rates of a flux-cored wire and the clean, slag-free finish of a solid wire. Because it is a seamless, copper-coated wire, it feeds through your liner and gun with minimal drag and excellent electrical contact, reducing tip wear and preventing the bird-nesting often associated with softer cored wires.

Welders will appreciate the exceptionally stable arc and minimal spatter this wire produces. The spray transfer mode achieved with mixed gas (Argon/CO2) creates a smooth bead profile with excellent wetting action, meaning less time grinding and more time welding. The "MC" (Metal Core) formulation produces small silicon islands rather than a heavy slag covering, so multi-pass welding is often possible without inter-pass deslagging. This feature alone can drastically improve your daily throughput on heavy fillet welds and groove joints.

Packaged in a convenient 16kg (approx. 35 lb) spool, this wire is ready for long runs in the shop. The E70C-6M-H4 classification confirms its quality, ensuring you get strong, ductile welds with incredibly low hydrogen content. Whether you are welding manually or setting up a robot, the Diamondspark Guard 420 MC gives you the control and speed you need to tackle heavy fabrication jobs with confidence.
