Ain't that the truth, I've taught a couple of people the basics of mig welding, simple things like setting the machine up correctly for them makes a massive difference so that they can actually lay down some decent beads and get some practice in. Usually they don't need much more than that and the odd pointer on technique and they are away.With hands on tuition from a competent welder I reckon you could learn more about stick,tig,gas or mig welding in an hour than watching or reading months of videos and books.
