Because it is a beginner I can not do very well, but I think that I want to practice because there is room for materials as well. Then, since it is difficult to select materials, it is very helpful if there are things like trial sets that come in packs of various sizes as long as possible, please consider the examination.
Since it is the first welding, the temperature control does not go well and it can be unwelded or burned. There is nothing wrong with the welding rod itself. I will do my best to successfully weld with practice repeatedly
