Premium low-hydrogen SMAW electrodes for carbon steel

Meet METAL MARLIN E7018 H4R, a 5 lb pack of 3/32 in diameter carbon steel stick electrodes designed to deliver reliable joints with a modern low-hydrogen flux. The electrodes conform to AWS A5.1 E7018 and ASME SFA-5.1 E7018 requirements, offering a dependable baseline for a wide range of fabrication tasks. The low-hydrogen chemistry helps promote consistent weld quality under typical conditions, while the durable packaging keeps moisture at bay from shop to field.

Users often notice a smooth, stable arc and a cleaner weld profile, aided by low spatter and easy slag removal. The H4R designation signals a flux chemistry that prioritizes toughness in the weld metal while remaining compatible with both AC and DC power sources. This combination can support steady progress on projects that demand predictable performance.

Key benefits

  • Low-hydrogen formula supports dependable weld quality for carbon steel projects.
  • Operates with both AC and DC power sources and in all positions (flat, horizontal, vertical, overhead).
  • High tensile strength with stable arc and reliable yield for durable joints.
  • Minimal spatter and easy slag removal to reduce cleanup time.
  • Vacuum-sealed, waterproof packaging preserves dryness, ready to weld out of the package.

Applications and practical use

  • Ideal for home upgrades, structural steel work, fabrication, piping systems, and heavy equipment components.
  • Suitable for shop or field projects where versatile, low-hydrogen electrodes are advantageous.

Packaging and storage

The electrodes arrive in vacuum-packed packaging designed to block moisture. Keep the package sealed when not in use and store in a dry environment to maintain a low-hydrogen status without pre-baking in many cases.

Specifications at a glance

  • Diameter: 3/32 in
  • Weight: 5 lb pack
