COREWELD C6 LF

COREWELD C6 LF

Coreweld C6 LF is a low manganese emissions, high efficiency, metal cored wire developed in response to new EPA* regulations and guidelines from ACGIH (American Conference of Government Industrial Hygienists) for Manganese fume exposure limits. With all the same enhanced features of ESAB’s standard Coreweld C6, Coreweld C6 LF has more than 50 percent lower manganese content and is designed to provide excellent operating qualities while significantly reducing the manganese levels in the welding fumes when compared to standard metal-cored electrodes of the same classification. ESAB’s optimized formulation aids users in their efforts to reduce exposure to manganese in the welding environment while providing good mechanical properties and low weld metal diffusible hydrogen levels. Coreweld C6 LF offers the same enhanced features of ESAB’s standard Coreweld C6 with welder-friendly operating characteristics, including consistent arc stability, very low spatter, good bead shape and minimal clean-up in an easy-to-use wire. Its low diffusible hydrogen level helps avoid hydrogen-induced cold cracking in the welding of high strength steel. Combining the Coreweld C6 LF low manganese formula with argon-based shielding gases and GMAW power supplies allows users to aggressively reduce the manganese concentration in welding fume while achieving the proven performance expected from ESAB, Coreweld C6 LF is well suited for both hand held and robotic or automated applications in the automotive industry, as well as for civil construction, mobile and heavy equipment, shipbuilding, rail car manufacturing, and general fabrication. Typical Diffusible Hydrogen: 4 ml/100g of deposited weld metal (with 75% Ar/25% CO2) *EPA 40CFR Part 63 Subpart XXXXXX;1.0% Mn, 0.1% Ni, 0.1% Cr, 0.1% Cd and 0.1% Pb, by total weight of the electrode.
