Kiswel 4MM Welding Rod 7018

Key specs include a 4 mm diameter, low-hydrogen resin-coated electrode, suitability for high-current welding, self-releasing slag for easy cleanup, and reliable performance in general steel welding with good arc stability.

This rod is intended for jointing mild steels and low-alloy steels, making it a versatile choice for general fabrication and repair work on common structural steels.

7018 electrodes offer stable arc behavior and strong, uniform weld beads, which helps maintain good results in vertical and overhead positions; the rod’s slag is designed to release smoothly to aid in multi-angle welding.

Prepare clean joints, strike the arc, and feed the electrode steadily to maintain a uniform arc. Weld in the required positions (including vertical/overhead) and allow the weld to cool. After welding, chip away slag and clean the surface for final inspection.

Store in a dry environment and keep in their original packaging or a dedicated welding rod oven to prevent moisture pickup, which can affect low-hydrogen performance.

Both are 7018 low-hydrogen electrodes. The 4 mm version is better suited for heavier joints and thicker sections, while the 3.2 mm variant is more maneuverable for lighter work and finer detail.

Both are low-hydrogen 7018 electrodes. The Kiswel 4 mm rod offers options for heavier-section welding, whereas the ESAB 3.2 mm counterpart is often preferred for lighter, more delicate welds. Choose based on joint thickness and required weld properties.

Typical applications include fabrication and repair of structural steel, machinery frames, and other mild to low-alloy steel welds where reliable performance and good weld appearance are desired.

Yes. Wear appropriate PPE (gloves, helmet, eye protection, and protective clothing). Work in a well-ventilated area. Because it is a low-hydrogen electrode, store and dry the rod properly to maintain performance and prevent hydrogen-related issues.

It is designed for dependable, high-quality welds on mild and low-alloy steels, with features like smooth starts, stable arcs, and easy slag removal. Its value depends on your project scale and need for consistent results in fabrication and repair.

Ensure joints are clean and properly fit; use appropriate current for the 4 mm diameter; maintain a steady travel speed to achieve uniform beads; allow slag to form and then remove it cleanly; store electrodes dry to preserve low-hydrogen performance.

Alternative options include Kiswel 7018 in 3.2 mm and ESAB 7018 in 3.2 mm, which are available on Fepy.
