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

Premium Seamless Metal-Cored Wire for High-Performance Fabrication

The Böhler Diamondspark Guard 420 MC is a state-of-the-art seamless metal-cored wire designed for the welding of mild and medium strength steels. Engineered with precision, this .052-inch diameter wire comes in a 16kg spool and meets the AWS E70C-6M-H4 classification. Its seamless copper-coated tubular design offers exceptional resistance to moisture absorption, guaranteeing extremely low diffusible hydrogen levels (H4). This makes it a critical choice for applications where preventing hydrogen-induced cracking is paramount, such as in heavy structural steel fabrication and critical machinery manufacturing.

Unlike traditional folded wires, the Diamondspark Guard 420 MC provides superior current transfer and wire feeding characteristics, making it highly suitable for robotic and automated systems. The metal powder core allows for higher current densities, resulting in significantly faster deposition rates compared to solid wires. This efficiency translates to reduced welding time and lower overall production costs. The wire is formulated to operate with Argon/CO2 mixed shielding gases, providing a stable arc with a wide parameter window.

Industrially, this wire excels in sectors requiring high integrity welds with excellent mechanical properties. The 420 MPa yield strength designation ensures it meets the rigorous demands of modern engineering standards. Whether used for general construction, shipbuilding, or heavy equipment repair, the Diamondspark Guard 420 MC delivers consistent, high-quality results that professionals trust.
