Before starting with electric arc welding, they must, of course, have a working table, as much as possible of iron. They should also have an apron and a mask for welding, because if we do not use an apron, after a while the welding can have consequences, even if we do not use the mask for the eyes. If you want to learn to weld, you can repair the steel parts that have been damaged in your home, and you could even work as a welder and work on your own.
