DETAILS
UltraCore® 70C from Lincoln Electric is a gas-shielded flux-cored wire designed for low fume generation rates and controlled H8 diffusible hydrogen levels. It is recommended for both single or multiple pass welding in either semi-automatic or automatic applications. This product is manufactured with steel made and melted in the U.S.A. It complies to Buy America (BA), Buy American (BAA), Build America, Buy America (BABA), and American Iron & Steel (AIS) standards.
Features
- High deposition in the flat and horizontal positions
- Low fume generation rates
- Designed for welding with 100% CO2 shielding gas
- Premium arc performance and bead appearance
- ProTech® foil bag packaging
- This product is manufactured with steel made and melted in the U.S.A. It complies to Buy America (BA), Buy American (BAA), Build America, Buy America (BABA), and American Iron & Steel (AIS) standards.
