Is argon arc welding easy to learn?

Learning is easier than welding. If you don't want to go to school, find a machinery factory and find a master to take care of it. Generally speaking, a good understanding of three months is almost enough. But it also depends on whether the material you touch is thick or thin. Thin ones are refined, and thick ones are just fine, usually for plates. This is a physical activity, and the key is to practice more.
