  • 33 lb Spool

DETAILS

Designed for high strength, low-alloy applications using 75% Argon/25% CO2. The use of mixed shielding gas stabilizes arc characteristics, reduces spatter levels, and washes out the weld bead for a flat appearance.

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 75-85% Argon/Balance 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.
