Lincoln Electric ED030569 E7018 H8 Welding Electrode

Product Description

The LINCOLN ELECTRIC ED030569 is an E7018 H8 classification low-hydrogen welding electrode designed for shielded metal arc welding (SMAW) of mild steel. The electrode measures 1/8 inch in diameter and 14 inches in length. The H8 designation indicates a diffusible hydrogen limit of 8 mL per 100 g of deposited weld metal, reducing the risk of hydrogen-induced cracking in the weld zone. This electrode is commonly used by certified welders and pipe fitters working on structural, pressure vessel, and general fabrication applications where weld quality and mechanical properties are critical.

This E7018 H8 electrode is suited for flat, horizontal, vertical, and overhead welding positions on mild steel base materials. It is a go-to choice in structural steel fabrication shops, field welding operations, and maintenance and repair environments where low-hydrogen deposits and smooth arc performance are required. The rod is packaged individually and is appropriate for both production and intermittent welding tasks requiring controlled hydrogen content.

Key Features

• E7018 H8 classification with diffusible hydrogen limit of 8 mL per 100 g of deposited weld metal
• 1/8 inch diameter for moderate to heavy deposition on mild steel
• 14 inch rod length standard for SMAW electrode holders
• Low-hydrogen flux coating reduces risk of underbead and cold cracking
• Suitable for all-position welding on mild steel

Compatibility

Designed as an OEM-style replacement or standard consumable for SMAW processes on mild steel base materials requiring E7018 H8 classification electrodes.

Installation Notes

Installation and use of this electrode should be performed by a qualified welder following applicable AWS and OSHA guidelines. Low-hydrogen electrodes must be stored in a rod oven or sealed container to prevent moisture absorption, which can compromise the H8 hydrogen rating. Before welding, ensure the base material is clean, dry, and properly fitted, and verify that the welding machine is set to the appropriate amperage range for 1/8 inch E7018 electrodes. Do not use electrodes that have been exposed to excessive moisture without proper re-drying per the manufacturer's reconditioning procedures.
