61784000 - Bonarc E6010 4.0mm Cellulose Stick Electrode

Reliable Deep Penetration Welding with Bonarc 6010

The Bonarc 6010 4.0mm Stick Electrode is a premium choice for welders requiring deep penetration and a fast-freezing puddle. Designed with a high cellulose sodium coating, this electrode is engineered to meet the rigorous demands of pipe welding, shipbuilding, and general construction. The 4.0mm diameter provides substantial deposition rates while maintaining the control necessary for critical root passes and out-of-position work.

One of the standout features of the Bonarc 6010 is its ability to handle less-than-perfect base metals. Whether you are working on steel that is rusty, painted, or slightly oily, the digging arc of this electrode burns through contaminants to ensure a sound weld. This makes it an indispensable tool for maintenance and repair operations where surface preparation cannot always be perfect. The forceful arc ensures fusion deep into the base metal, providing the structural integrity required for pressure vessels and heavy machinery.

This electrode is classified as an all-position rod, meaning it excels in flat, horizontal, vertical, and overhead positions. Its fast-freeze characteristic allows the welder to control the molten pool effectively, preventing sagging or dripping when welding vertically or overhead. This versatility reduces the need to switch electrodes for different joint orientations, streamlining the workflow on complex projects.

Bonarc has formulated this electrode to provide a stable arc on DCEP (Direct Current Electrode Positive) polarity. The slag produced is thin and brittle, making for quick and easy removal, which is essential for multi-pass welding applications to prevent slag inclusions. Whether you are a professional pipe welder or a fabricator looking for a reliable rod for structural steel, the Bonarc 6010 4.0mm delivers consistent performance and quality results.
