Method for the setting of electrodes in electrolysis cells, especially setting of carbonazious anodes (3) in cells (1) for producing aluminium according to the Hall-Heroult process, where the cathode of the cells contains a bath (13) consisting of aluminium oxide dissolved in melted cryolite, and where the aluminium metal is deposited on the bottom of the cathode. The method is characterized in that each anode in connection with their production (assembly) is provided with reference marks (16 and/or 17), for instance by providing the anode rod with a paint mark, which defines a predetermined distance from the bottom side of the anode to the cathode. That the anodes thereafter are positioned or set according to a rule (18) having reference points (19) each defining the expected anode consumption pr. unit of time, whereby the reference mark (16 or 17) on said anode rod should correspond to a reference point (19) on the rule (18) which is in accordance with the expected setting height, and that the rule (18) for each anode is fixed for instance to the anode bars (7) of the cells in a predetermined and equal distance from the metal plane (15). By means of this setting method a more even current absorption is achieved and the carbon consumption is reduced.
