The correct welding technology allows you to get a high-quality metal product, which is able to last for quite a long period of time. Today, almost everyone can learn to use electric welding apparatus.
To do this, you must have certain practical knowledge and follow the elementary rules of welding. They allow you to avoid common mistakes of novice welders. Everyone can perform welding work at home. To this end, it is recommended to become familiar with the basic theory of the electric welding apparatus.
