Experience the difference that a premium coating makes with Lincoln Electric's Excalibur® 7018-1 MR® stick electrodes. Designed specifically to address the common pain points of Shielded Metal Arc Welding (SMAW), this electrode (ED038107) offers an unparalleled combination of arc stability, puddle clarity, and mechanical integrity. The 3/32-inch diameter is perfect for thinner gauge materials or root passes in heavy plate, providing precise control and deep penetration where it counts.
Superior Arc Performance
The Excalibur 7018-1 MR is renowned for its "square burn-off." Unlike inferior rods that fingernail or burn unevenly, the Excalibur coating burns back evenly with the core wire, keeping the arc focused and the puddle visible. This visibility allows the welder to manipulate the weld pool with confidence, ensuring proper tie-in at the toes and preventing defects like undercut or lack of fusion. The soft, quiet arc generates very little spatter, keeping your workpiece clean and reducing grinding time.
Moisture Resistance and Code Compliance
For code-quality work, hydrogen control is non-negotiable. The Excalibur 7018-1 MR features a specialized coating that resists moisture pickup even in high-humidity environments. Rated as H4R, it guarantees less than 4ml of diffusible hydrogen per 100g of weld metal, drastically lowering the risk of hydrogen-induced cracking. Furthermore, the "-1" suffix indicates improved impact toughness at low temperatures, making these rods suitable for projects exposed to harsh cold environments, such as offshore structures or northern pipelines.
All-Position Versatility
Whether you are running vertical-up stringers or overhead fillets, the fast-freezing slag system of the Excalibur 7018-1 MR supports the puddle effectively without choking the arc. It operates exceptionally well on DCEP (Direct Current Electrode Positive) but is also compatible with AC power sources, providing flexibility depending on your machine setup. Packaged in a hermetically sealed 50 lb can, these electrodes are ready to perform right off the shelf.
