METAL MARLIN E7018 H4R Welding Rod 1/8 inch, 5 lb Pack – Low-Hydrogen SMAW Electrodes (Vacuum-Sealed)

Premium Low-Hydrogen Electrodes for Carbon Steel

METAL MARLIN E7018 H4R welding rods come in a convenient 5 lb vacuum-sealed pack, designed to keep a dry, low-hydrogen profile from the moment you open the container. These electrodes align with AWS A5.1 E7018 and ASME SFA-5.1 E7018 requirements, offering a reliable option for code-conscious projects and everyday steel work alike. The coating and chemistry are engineered to support strong, consistent joints on carbon steel without sacrificing ease of use.

All-Position Welding Versatility

Crafted for both AC and DC welders, these 1/8 inch electrodes deliver a stable arc across different orientations. Flat, vertical, overhead, or horizontal work becomes feasible in shop settings or on the job site, giving you flexibility when access is limited or tools vary.

• AC/DC compatibility supports diverse welding setups
• Stable arc helps reduce wandering and spatter in challenging positions
• All-position capability suits both fabrication and maintenance tasks

Strong, Cleaner Welds with Real-World Strength

Expect durable joints with tensile strength in the typical range of 70,000–84,000 psi and yield above 58,000 psi. The technology behind H4R electrodes aims for smooth arcs and easier slag removal, which translates to cleaner welds and less cleanup after work.

• Low hydrogen flux supports reliable weld quality
• Reduced spatter contributes to neater weld seams
• Coating aids in steady heat input for predictable results

Wide Range of Applications

From home improvements to structural fabrication, E7018 H4R is suited for projects in structural steel, fabrication shops, piping, heavy equipment, and general metalwork. It’s a versatile choice when you need dependable performance across common carbon steel tasks.

• Structural steel and fabrication projects
• Maintenance and repair on heavy equipment
• Piping systems and pressure-related components

Vacuum Packed for Readiness

The E7018 H4R electrodes arrive in vacuum-packed packaging to block moisture and maintain a low-hydrogen status. This protection supports reliable use straight from the package, minimizing the need for pre-baking while helping to reduce porosity risks when stored correctly.
