ED037425 - Lincoln Excalibur 7018 XMR 3/32" Stick Electrode - 30lb Carton

Lincoln Excalibur 7018 XMR: The Standard for Low Hydrogen Integrity

The Lincoln Electric Excalibur® 7018 XMR® (ED037425) represents a significant advancement in Shielded Metal Arc Welding (SMAW) consumables. Designed specifically for critical applications requiring the highest levels of weld integrity, this E7018 H4R electrode addresses one of the most persistent challenges in the industry: moisture pickup. The "XMR" designation stands for Extreme Moisture Resistance, a proprietary coating technology that significantly extends the exposure time of the electrode. While standard E7018 electrodes may absorb moisture rapidly once removed from their hermetically sealed containers, the Excalibur 7018 XMR resists moisture pickup up to 60% better than competitive equivalents.

This electrode is engineered to meet and exceed AWS A5 moisture content limits. It maintains its H4R low-hydrogen classification even after 24 hours of exposure to relative humidity, providing a substantial safety margin for fabricators and reducing the frequency of redrying cycles. This characteristic is particularly valuable in industries such as power generation, petrochemical processing, and pressure vessel fabrication where hydrogen-induced cracking is a critical concern. The ED037425 SKU is supplied in a 30 lb master carton, which contains three individual 10 lb Easy Open Cans, ensuring that inventory remains protected until the moment of use.

Beyond its moisture-resistant properties, the Excalibur 7018 XMR delivers exceptional operability. Welders benefit from a smooth, stable arc and a clear puddle that enhances visibility and control. The coating is formulated to resist flaking even during extreme bending, which is often required when accessing difficult joints. With reduced arc starting porosity and superior slag detachability, this electrode improves overall productivity and weld quality in demanding structural and pipe welding environments.
