Esab Atomarc 7018 255011819 Low Hydrogen Iron Powder Covered Electrode, 1/8 Inch Dia. X 14 Inch L, 50 Lb Hermetically Sealed 255011819 ESA255011819

Detailed Description

Atom Arc 7018 is an all-position low hydrogen moisture resistant electrode. The wider operating ranges and smooth weld metal transfer minimizes post weld clean up. This premium quality electrode meets a multitude of codes and welding specifications. Atom Arc 7018 was developed to weld carbon and low-alloy steels, including a variety of hardenable steels

  • Easy slag removal
  • Capable of x-ray quality and excellent impact properties
  • Premium arc performance
  • For welding hardenable steels, cold rolled steels, or other steels, low alloy and mild steels when stress relieving normally would be required but cannot be done, all-position welding, general fabrication, power generation, petrochemical, pressure vessels, pressure piping
  • Flat, horizontal, vertical up, overhead welding positions
  • Medium penetration
  • 2.6 lb/hr at 120 amp, 2.7 lb/hr at 140 amp deposition rate, 71.6% at 120 amp, 70.9% at 140 amp efficiency
