Metal Marlin E7018 H4R Welding Rod 3/32”, 5 lb Pack, Premium Quality Low Hydrogen Carbon Steel Stick Electrode (SMAW), Vacuum Sealed & Waterproof Durable Packaging, Suitable for Stick Welding Tools — Open-Box, 15% Off

【 AWS-COMPLIANT E7018 LOW-HYDROGEN ELECTRODES 】: Metal Marlin H4R provides premium quality, low-hydrogen, arc welding carbon steel stick electrodes that ensure strong, reliable welds for all projects, ensuring strong and reliable welds with low hydrogen content, conforming to AWS A5.1 E7018 and ASME SFA-5.1 E7018 requirements.

【 ALL POSITION WELDING VERSATILITY 】: Engineered for use with both AC and DC welders, these 3/32” steel electrodes deliver reliable performance and flexibility in all positions (flat, vertical, overhead, and horizontal), making them ideal for field and shop applications.

【 HIGH TENSILE STRENGTH & CLEANER WELDS 】: Tensile strength of approximately 70,000–84,000 psi and yield strength of 58,000+ psi deliver durable, code-quality joints. Our 7018 electrodes produce a smooth, stable arc with low spatter and easy slag removal for cleaner welds and reduced cleanup time.

【 WIDE RANGE OF APPLICATION 】: The E7018 welding rod is used in a wide range of applications, be it in home improvement, structural steel, fabrication, pressure vessel manufacturing, piping systems, heavy equipment manufacturing, or power plants.

【 VACUUM PACKED PACKAGING 】: Our E7018 H4R electrodes are vacuum-packed to block moisture and maintain low-hydrogen status. This ensures rods arrive dry and ready for use, eliminating the need for pre-baking and reducing the risk of hydrogen-induced cracking and porosity for high-quality, reliable welds.

Metal Marlin E7018 H4R is a premium low-hydrogen, iron-powder stick electrode engineered for demanding structural and fabrication work where weld integrity and toughness are critical. E7018 H4R electrodes are designed to deliver smooth, stable arcs and high-strength welds with very low diffusible hydrogen levels, helping reduce the risk of cracking in restrained or highly stressed joints.​ Crafted with precision, Metal Marlin E7018 H4R is ideal for medium to heavy-duty applications such as structural steel, heavy equipment, bridges, building frames, pressure components, and critical fabrication in shop or field environments. Its low-hydrogen flux and iron-powder formulation provide deep fusion with controlled penetration and excellent mechanical properties, typically meeting 70 ksi tensile strength requirements for code-quality welds on carbon and low-alloy steels.​ This electrode is designed for all-position welding (flat, horizontal, vertical, and overhead) and is suitable for use on AC or DCEP power sources common in professional welding machines. The easy-starting, low-spatter arc and smooth metal transfer make Metal Marlin E7018 H4R a strong choice for welders who require consistent bead appearance, easy slag removal, and reliable performance in production or field conditions.​ Each pack is manufactured and packaged to meet H4R low-moisture requirements, helping protect the flux coating from humidity and minimizing hydrogen pickup during storage. This moisture-resistant packaging supports stable arc starts and consistent weld quality over time, reducing the need for reconditioning and helping maintain compliance with welding procedures that specify low-hydrogen consumables. Metal Marlin E7018 H4R is a dependable, go-to electrode for welders who need a robust low-hydrogen rod for structural fabrication, repair, and maintenance on carbon and low-alloy steels. Whether completing critical structural welds, heavy equipment repairs, or high-duty industrial projects, it is designed to be a must-have electrode in any professional welding operation.
