70S-6 CF (Copper Free) is the latest generation of carbon steel wire designed to increase total productivity while reducing your total welding costs. Copper Free wire is specially designed to reduce wear on consumables and produce great clean welds that require minimal clean-up. This is all to help improve arc on time to keep you welding. The immensely low spatter, incredibly little fume, and superior arc stability culminates in excellent weldability. The coating on the wire eliminates copper contamination of your feeding equipment and significantly prolongs the life of your contact tips, nozzles, gas diffusers, liners, and feed rolls. Exceptionally low fume emission creates a cleaner and healthier work environment.
