STARTECHWELD 7018 1/8 Inch Rod
STARTECHWELD 7018 1/8 inch welding rods are designed for carbon steel, high-tensile steel, low alloy steel, and free-machining steels. They use a low-hydrogen iron powder coating to support a steady, quiet arc and low spatter, while promoting easy re-striking and high deposition efficiency. The result is a bead that wets smoothly and reveals a consistent ripple when slag is removed. This electrode also delivers strong Charpy impact values at sub-zero temperatures, making it suitable for cold-weather and high-stress applications.
- Low-hydrogen, all-position electrode for multiple steels
- Quiet steady arc, low spatter, easy re-striking
- High deposition efficiency with clean slag and rippled bead
- X-ray quality weld deposit with excellent Charpy impact values at -20°F
PGN E7018 3/32 Inch 5LB Rod
PGN E7018 welding rods offer impressive tensile strength and reliability for structural steel and pipelines. With a low-hydrogen coating, these electrodes help reduce cracking in high-stress joints. They’re designed for AC and DC currents, providing flexibility for varied power sources and job-site setups. The combination of all-position usability and robust deposition makes them a solid choice for demanding fabrication work and field repairs where weld quality matters.

Buying Guide
Key considerations for choosing E7018 rods
When selecting 7018 electrodes, consider coating type, position capability, and compatibility with your power source. A low-hydrogen coating helps prevent hydrogen-induced cracking in carbon and low-alloy steels, especially in higher-strength materials. All-position usability expands where the rod can be effectively used, including overhead and vertical welding. Verify the current type—AC, DC, or both—as this affects arc control, penetration, and prep work. Packaging and shelf life also matter for storage in shop conditions and field kits.
All-position performance and arc stability
All-position electrodes enable welding in multiple orientations without sacrificing bead quality. Electrodes with stable arcs and low spatter reduce cleanup time and improve consistency. If your work includes structural fabrications or repairs in awkward positions, prioritize rods that explicitly state all-position compatibility and arc stability in their specs.
Coating options and hydrogen content
Low-hydrogen coatings are common for 7018 rods, but the exact formulation varies by brand. Some products highlight advanced additives to reduce porosity or improve wetting action. When hydrogen embrittlement is a concern—such as high-stress joints or outdoor joints in cold climates—choose rods that emphasize low-hydrogen chemistry and reliable re-striking characteristics.
Size, packaging, and storage
Electrode diameter and length affect welding control and deposition rate. Common sizes include 1/8 and 3/32 inch diameters. Packaging ranges from multipack pails to smaller boxes; larger packs like 50 pounds are convenient for shop use but require proper storage to maintain low-hydrogen properties. Store electrodes in a dry, odor-free environment to prevent moisture absorption that can compromise weld quality.
Power compatibility and job-site considerations
AC and DC compatibility broadens where and how you can weld. Some rods perform best with specific current types, while others are versatile across both. If you work with portable welders or generators, verify current compatibility and any recommended polarity for optimum bead shape and penetration. For field work, rods with robust slag removal and stable arc can reduce rework and speed up turnaround.
