A multi-unit welding apparatus has a row of electric welding units all of which are connected in parallel with a single welding transformer through an electric conductor assembly. The electric conduction assembly includes a single strip of electric conductor and a double-folded strip of electrode conductor which are connected at one end to positive and negative terminals of a secondary winding of the welding transformer and are arranged along and connected to the welding units of the welding unit row so that the combined length of conductor between secondary winding and each welding unit is the same for all welding units.
