Excalibur® 7018 MR® SMAW Electrode – 50 lb Moisture-Resistant Canister #ED034307

Tackle critical welds with confidence using the Lincoln Electric Excalibur® 7018 MR® stick electrode. This 7/32" x 18" low-hydrogen electrode delivers 70,000 psi tensile strength and 58,000 psi yield strength, engineered for code-quality welds in demanding environments. Packaged in a 50 lb easy-open can with patented MR® (Moisture Resistant) coating, it stays weld-ready even in humid Wisconsin workshops—no re-drying required.

Supported Welding/Cutting Processes

  • Shielded Metal Arc Welding (SMAW)

Highlights

  • MR® Coating Technology: Withstands 80% relative humidity for 9+ months (per AWS standards).
  • Low Spatter & Smooth Arc: Minimizes cleanup with stable 22-35V DC operation.
  • All-Position Welding: Vertical-up, overhead, and flat/horizontal capabilities.
  • AWS E7018 Classification: Meets stringent hydrogen control (<4ml/100g).
  • Easy-Open Can: Secures electrodes from moisture between jobs.

Applications

  • Structural steel fabrication (bridges, buildings)
  • High-stress pipe welding (API, ASME codes)
  • Repairing heavy machinery and agricultural equipment
  • Maintenance in humid or outdoor environments

Benefits of Lincoln Electric Excalibur® 7018 MR® Stick Electrode

  • Eliminates Hydrogen Cracking: MR® coating prevents porosity, even after prolonged storage.
  • Outperforms Standard 7018: Faster deposition rates in vertical-up positions.
  • Saves Time & Money: Skip oven storage – weld directly from the can.
