Lincoln Excalibur 8018-C3 1/8-Inch Stick Electrode (30lb Carton)

Premium Performance for Critical Welds

When your weld quality is under the microscope, you need a rod that performs flawlessly every time you strike an arc. The Lincoln Electric Excalibur® 8018-C3 MR® is built for the professional welder who demands superior handling and X-ray quality results. This 1/8-inch stick electrode is formulated to deposit a 1% nickel weld metal, giving you the extra toughness and strength needed for critical jobs like cross-country pipelines, process piping, and heavy structural fabrication. If you are welding on projects that require adherence to NACE MR0175 for sour gas, this is the rod that gets the job done right.

What sets the Excalibur series apart is the welder-focused experience. We know that fighting with your consumables leads to fatigue and defects, which is why this electrode is designed for premium arc performance. It offers an incredibly easy strike and re-strike, whether the rod is hot or cold, reducing the chance of porosity at the start of the weld. The arc is soft yet penetrating, providing excellent puddle control in all positions. Perhaps most importantly, the slag removal is effortless. In many cases, the slag will lift by itself as it cools, or require just a light tap to reveal a clean, smooth bead underneath. This saves you valuable time on cleanup and reduces the risk of slag inclusions in multi-pass welds.

The "MR" in the name stands for Moisture Resistant, meaning this rod is designed to resist absorbing humidity from the air. This low-hydrogen characteristic (H4R) is vital for preventing cracking and ensuring the integrity of your welds in harsh environments. The packaging is just as practical as the rod itself; the 30 lb master carton contains three 10 lb Easy Open Cans. These cans are designed to be opened without tools, protecting the rods until you are ready to burn them, and making them easy to transport around the job site.

Whether you are in the shipyard, on a pipeline spread, or in the fab shop, the Excalibur 8018-C3 gives you the confidence to tackle complex alloy welding. The consistent burn-off and resistance to fingernailing mean you can focus on your technique rather than compensating for the rod. Upgrade your stick welding game with the reliability and performance of Lincoln Electric's Excalibur series.
