S119932-089 - Hobart 418 E7018-1 Stick Electrode 3/32 Inch 10lb Pack

Hobart 418 Low Hydrogen Stick Electrode

The Hobart 418 is a premium quality, low hydrogen stick electrode designed for general purpose fabrication and critical structural work. Classified as E7018 H4R and E7018-1 H4R, this electrode provides superior mechanical properties and crack resistance, making it an essential consumable for industries ranging from petrochemical plants to heavy equipment repair. The 3/32 inch (2.4 mm) diameter is versatile for various material thicknesses, allowing for precise control in detailed applications.

Engineered for performance, the Hobart 418 excels in single and multiple pass applications on mild steel, low alloy structural steel, and high carbon castings. Its formulation ensures excellent arc stability, which is crucial for maintaining weld integrity across complex joints. The electrode operates effectively on both DCEP (Direct Current Electrode Positive) and AC (Alternating Current), providing flexibility depending on the available power source and specific job requirements. The H4R designation signifies that the electrode meets stringent requirements for moisture resistance and low diffusible hydrogen levels, reducing the risk of hydrogen-induced cracking in the heat-affected zone.

This 10 lb (4.5 kg) Plastic Pak is designed to protect the electrodes from environmental moisture, ensuring they remain in optimal condition for welding. The Hobart 418 is widely used in the construction of boilers, pressure vessels, piping systems, and railcars. Its ability to perform in all welding positions—flat, horizontal, vertical up, and overhead—makes it a go-to solution for infrastructure repair and rebuilding projects that must adhere to State and Federal Transportation Codes.

Whether used for offshore fabrication, mining equipment maintenance, or general steel structure assembly, the Hobart 418 delivers consistent, high-quality results. Its ease of slag removal and low spatter characteristics further enhance operational efficiency by minimizing post-weld cleaning time.
