The elongated welding electrode has a flexible welding flux material coated on the outside surface of a flexible welding metal core. The flux material is provided in short equal length segments with slots formed between adjacent segments to expose the metal core therein. The welding current can be applied to the weld through the core in a plurality of the exposed slots so that a large current with relatively no current loss can be used in the welding operation. The slots also serve as means to facilitate the automatic advancement of the electrode through the welding equipment. The welding flux coating over the metal core of the electrode is covered with flexible protective coatings so that it is extremely flexible such that the flux coating will not break off from the metal core during winding on and unwinding from the carrier reel.
