Tutorial how to learn to weld with an electric arc electrode, where some recommendations are indicated that explain how to weld correctly and thus be able to weld various materials such as cast iron, stainless steel, etc. When we start this activity it is very important to keep in mind some recommendations: Work in a clean, dry and ventilated environment, since toxic gases are created, it is good to have a fire extinguisher, the area to be welded must be clean to obtain a good result. of quality, in case it is welded on old welds, they must be eliminated with the help of a small grinder, it must be verified that the clamp that carries the negative current that comes out of the welder is attached to the metal and that it does not obstruct the process. The electrode to be used is according to the thickness of the material to be welded, the regulation of the amperage is carried out according to the diameter, type of electrode and thickness of the material to be welded, very low amperage does not allow penetration of the filler material, on the other hand when the amperage is too high produces splashes.
One of the biggest problems when we want to learn to weld with a coated arc is that the electrode sticks to the material, for this we must quickly bend in the opposite direction to the advance, if the electrode still does not come off we must detach it from the electrode holder, it must be preheated the electrode making scraping movements in the form of "C" to avoid vertical impact.
