Detalles
Smooth arc transfer, low spatter and good bead appearance make this a top quality electrode. Operators will enjoy the well directed arc with small ball transfer.
Características
- Smooth arc transfer and low spatter
- Designed for welding with either 100% CO2 or 75-82% Argon/balance CO2 shielding gases
- Good bead appearance
- Fast freezing slag for out-of-position welding
- 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.
