Abstract
A flux cored tubular metallic arc cutting electrode having a steel tube with a core composition of particulate carbonaceous material which is drawn and compacted within the steel tube by reducing the size of the tube. Preferably the carbonaceous material contains at least 75% carbon and additive selected from the group consisting of arc stabilizers, fluxing agents, and gas formers. The electrode is characterized in use by reduced dross formation.
