DETAILS
Designed for high deposition, out-of-position welding for structural fabrication in seismic zones. Recommended for single or multiple pass welding of 4.8 mm (3/16 in) and heavier carbon steel.
Features
- High deposition rates for out-of-position welding
- Penetrating arc
- Fast freezing, easy to remove slag system
- Meets AWS D1.8 seismic lot waiver requirements
- Notes: AWS D1.8 structural steel seismic supplement test data can be found at the Lincoln Electric Certificate Center.
