I liked his horizontal welding. I struggle with that and vertical too. I think that there is a great deal of the success of that down to the quality of the welding set. Skill too absolutely, but a really good set makes a huge difference to your welding. I think I might upgrade mine soon. it's good for most stuff, but I'd like to go 200 amp plus and maybe even go inverter / electronic. It's done some work has that little set.
