It is DC or AC = WRONG!

There have been quite a few so called "welding instructors" online on various forms of social media from Instagram, to TikTok, to TH-cam as well. Since I have taught welding in a welding department of a community college, I do want the most accurate teaching I can because I know how vital it can be to welding students. As a former welding instructor, I want to provide all welding students with the best information I can provide as well as for those who are considering entering the welding field.
