E6013 have a flux covering which makes slag removal easy and gives a smooth arc transfer. This is particularly the case for the small diameter 3/32”. This permits satisfactory operation with lower open-circuit AC voltage. E6013 electrodes were designed specifically for sheet metal work. Coverings of E6013 electrodes contain rutile, cellulose, ferromanganese, potassium silicate as a binder, and other siliceous materials. The potassium compounds permit the electrodes to operate at low amperages and low open-circuit voltages. Fillet welds tend to have a flat to convex weld face with even ripples in the horizontal welding position. The arc action tends to be quiet and the slag is fairly fluid. Pinnacle Alloys E6013 is an excellent choice for sheet metal welding, general purpose fabrication, machine parts, metal buildings, and shaft
