A method of arc-joining a workpiece with a consumable electrode and with the use of an inert gas shield and a short arc is disclosed. Material is dispensed by the melting electrode to the workpiece while an electronically controlled electrical short circuit is formed. An inert gas is used that consists of 50 to 5000 vpm (0.005 to 0.5 vol. %) of oxygen, carbon dioxide, nitrogen monoxide, nitrogen, dinitrogen monoxide, or of a mixture of these gases, in argon or in an argon/helium mixture.
