The Hobart 418 is a high-performance 5/32-inch (4 mm) stick electrode designed to meet the rigorous demands of heavy industrial welding. Classified as AWS E7018 H4R and E7018-1 H4R, this electrode is engineered for applications requiring superior impact toughness and low hydrogen content. It is an excellent choice for welding low alloy structural steels, high carbon castings, and pressure vessels where weld integrity is paramount. The "H4R" designation indicates a moisture-resistant coating that remains effective even in humid environments, significantly reducing the risk of hydrogen-induced cracking in critical welds.
Industrial professionals appreciate the Hobart 418 for its versatility and operational efficiency. It performs exceptionally well on both DCEP and AC currents, providing flexibility depending on the available power source. The electrode delivers a stable, smooth arc that is easy to control, making it suitable for all welding positions—flat, horizontal, vertical up, and overhead. This all-position capability allows for seamless transitions between different joint configurations without the need to change consumables, thereby streamlining workflow in complex fabrication projects.
Packaged in a durable 5 lb (2 kg) Plastic Pak, these electrodes are protected from environmental contaminants and moisture ingress during storage and transport. This packaging is ideal for maintenance and repair operations (MRO) where large bulk containers may not be necessary. Common applications include power generation plants, petrochemical facilities, mining equipment repair, railcar construction, and general offshore fabrication. With its combination of excellent mechanical properties, easy slag removal, and low spatter, the Hobart 418 ensures high-quality results and reduced post-weld cleanup costs.
