Lincoln® CarbonElite™ Pointed Carbon Arc Gouging Electrodes - DC Copper Coated KP3800Box of 50 - Genuine Lincoln® CarbonElite™ Pointed Carbon Arc Gouging Electrodes are available in 1/8" to 1/2" diameters. They are manufactured with a proprietary synthetic graphite formula that extends electrode life and maximizes metal removal, while producing uniform grooves. A full copper coating reduces heat and provides consistent arc starting and excellent arc stability.PLEASE NOTE: 1/8" DIAMETER IS A BOX OF 100, INSTEAD OF 50.ApplicationsRemoving defective welds Removing surface welds for re-surfacing Preparing joints for welding Back-gouging base material to allow for a full penetration weld depositFeatures Premium synthetic graphite composition extends electrode life to maximize metal removal Full copper coating improves arc stability and reduces heat generation Consistent melt-off rate for smooth, uniform grooves High density formula increases durability All electrodes are 12" long, except 1/2" - which are 14" long.
