Manual metal arc electrode with an efficiency over 100% -

The method used to determine the efficiency of manual metal arc electrodes is defined in ISO 2401:1972 (BS EN 22401:1994) 'Covered electrodes - Determination of the efficiency, metal recovery and deposition coefficient'. The electrode efficiency is calculated by dividing the mass of weld metal deposited by the mass of core wire consumed.
