DETAILS

Designed for high strength, low-alloy applications using 100% CO2. These electrodes exhibit robust impact properties, even with a notch offset of 2.5 mm from weld centerline, as well as superior crack resistance, due to low diffusible hydrogen levels (4mL/100 grams of weld deposit max).

Features

  • Capable of producing weld deposits with impact toughness exceeding 88 - 123 J (65 - 91 ft·lbf) at -40°C (-40°F)
  • Designed for welding with 100% CO2 shielding gas
  • Premium arc performance and bead appearance
  • Meets AWS D1.8 seismic lot waiver requirements
  • ProTech® foil bag packaging
  • Notes: AWS D1.8 structural steel seismic supplement test data can be found at the Lincoln Electric Certificate Center.

Typical Applications

  • Bridge fabrication
  • Weathering steels
  • Offshore
  • Structural fabrication
  • NACE applications
