Hobart 418 E7018-1 Low Hydrogen Electrode

The Hobart 418 is a premium quality, low hydrogen stick electrode designed for heavy-duty industrial applications. Conforming to AWS E7018 H4R and E7018-1 H4R classifications, this 1/8-inch (3.2mm) electrode delivers exceptional mechanical properties and X-ray quality welds. It is engineered for single and multiple pass welding on carbon and low-alloy steels, making it a staple in sectors such as power generation, petrochemical processing, and heavy structural fabrication.

One of the defining characteristics of the Hobart 418 is its H4R designation, which indicates a moisture-resistant coating that limits diffusible hydrogen levels. This feature is critical for preventing hydrogen-induced cracking (cold cracking) in thick sections or restrained joints. The electrode operates smoothly on both DCEP (Direct Current Electrode Positive) and AC (Alternating Current), providing versatility across different power sources. Its formulation ensures a stable arc, excellent wetting action, and a flat bead contour, which helps prevent common defects like cold lap and undercutting.

Packaged in a durable 10 lb (4.5 kg) plastic pak, these 14-inch electrodes are protected from environmental moisture, ensuring they remain factory-fresh for critical code work. The Hobart 418 is particularly noted for its ease of use in all welding positions—flat, horizontal, vertical-up, and overhead—allowing operators to tackle complex joints without changing consumables. Whether used for fabricating pressure vessels, repairing mining equipment, or constructing railcars, the Hobart 418 delivers the reliability and performance demanded by professional welding codes.
