S115981-035 - Hobart 718 E7018 Stick Electrode 1/4" 50lb Can

Hobart 718 E7018 Stick Electrode Overview

The Hobart 718 is a premium quality, iron powder, low hydrogen electrode designed for high-deposition welding in the Shielded Metal Arc Welding (SMAW) process. Conforming to AWS A5.1 E7018 H4R specifications, this electrode is engineered to provide X-ray quality welds with excellent mechanical properties. The 1/4-inch (6.4mm) diameter is specifically suited for heavy fabrication environments where fill rate and joint penetration are critical factors. The addition of iron powder to the coating significantly increases the metal recovery rate, allowing for faster travel speeds and reduced welding time on thick sections.

This electrode exhibits a smooth, stable arc with minimal spatter, characteristic of high-quality E7018 consumables. It offers superior impact toughness, making it suitable for applications requiring resistance to cracking under stress or low temperatures. The "H4R" designation indicates a moisture-resistant coating that maintains low hydrogen levels (less than 4ml/100g) even after exposure to humid environments, reducing the risk of hydrogen-induced cracking. The Hobart 718 operates effectively on both Direct Current Electrode Positive (DCEP) and Alternating Current (AC), providing flexibility for various power source configurations.

Packaged in a 50lb hermetically sealed can, the electrodes are protected from atmospheric moisture during storage and transport, ensuring they are ready for critical code work immediately upon opening. The heavy slag produced is easily detachable, often curling off the weld bead, which minimizes post-weld cleaning labor. This product is widely utilized in the construction of bridges, pressure vessels, ship hulls, and heavy machinery.
