# Lincoln Electric LE B-248 H4R Low-Hydrogen Welding Electrode for Carbon and Low-Alloy Steel - E7018-1 H4R

The Lincoln Electric LE B-248 H4R is a low-hydrogen stick welding electrode classified to AWS A5.1 E7018-1 H4R , designed for SMAW/MMA welding on carbon and suitable low-alloy steels. Its moisture-resistant H4R basic coating delivers a diffusible hydrogen level of no more than 4ml per 100g of deposited weld metal, making it well suited to structurally demanding applications. Available in 2.5mm, 3.25mm and 4.0mm diameters at a standard 350mm length, it is a reliable choice for structural fabrication, heavy steel components and rigidly restrained structures. Key Features: Basic-coated stick electrode for SMAW/MMA welding on carbon and suitable low-alloy steels H4R moisture-resistant classification with diffusible hydrogen not exceeding 4ml per 100g of deposited weld metal High resistance to weld-metal cracking, suitable for rigidly restrained steel structures Runs on DC Electrode Positive (DC+) current Metal recovery of approximately 125% Suitable for all standard welding positions (E7018-1 classification) Specifications: AWS Classification: AWS A5.1 E7018-1 H4R EN ISO Classification: EN ISO 2560-A Welding Process: SMAW / MMA / Manual Metal Arc Welding Coating Type: Basic, Moisture Resistant Hydrogen Classification: H4R Compatible Materials: Carbon and Suitable Low-Alloy Steels Welding Current: DC Electrode Positive / DC+ Available Diameters: 2.5mm, 3.25mm, 4.0mm Electrode Length: 350mm Metal Recovery: Approximately 125%
