great video but i have to say once you have the knowledge then it really only is practice the skill would be very good to get good at but most industries uses welding robots... but good old fashion welding , is like good old fashion wood working it test skills. would be cool to have a bunch of different filler metals and the 5 basic cateogry machines mig , tig , arc , plasma , oxy/acet to practice on a bunch of different type metals mostly the important to AL and Fe ... i have so many cool ideas to try with welding on practice pieces if i ever get the chances. Nice to see there is great instructors that can teach the knowledge part
