S115958-035 - Hobart 718 E7018 3/16" Welding Rods (50lb Can)

Hobart 718 E7018 Stick Electrode (3/16")

The Hobart 718 is a premium quality, low-hydrogen stick electrode designed for heavy-duty structural welding applications. Classified as AWS E7018 H4R, this electrode features an iron powder coating that facilitates higher deposition rates and smoother travel speeds compared to standard low-hydrogen rods. The 3/16-inch diameter is ideal for filling large grooves and heavy fillet welds in plate thicknesses of 1/2 inch and greater.

Engineered for versatility, the Hobart 718 operates effectively on both DC+ (DCEP) and AC polarities, providing a stable arc with minimal spatter. Its formulation ensures excellent impact toughness at low temperatures, making it suitable for critical code work, including pressure vessels, bridges, and structural steel fabrication. The "H4R" designation indicates a moisture-resistant coating that remains low in diffusible hydrogen even after exposure to high humidity, significantly reducing the risk of hydrogen-induced cracking (cold cracking) in the weld zone.

This product comes in a 50lb hermetically sealed can, ensuring the electrodes are factory-fresh and ready for immediate use without initial re-baking, provided the seal is intact. The slag system is designed for easy removal, often peeling away on its own, which improves welder productivity and weld appearance. Whether used in the shop or the field, the Hobart 718 delivers consistent, X-ray quality results.
