I earn a living running a Tig upside down! Funny thing about pipe, ya gotta weld it all the way around! To Franks point Tig is a totally different creature. For our hobby MiG is much more adaptable and has a larger band for applications. But when ya need a Tig weld nothing else substitutes. PS I did not learn how to Tig overhead overnight!
I have only rudimentary knowledge... thank you Old Man Ray wherever you are. I still suck regardless of the material and format but it's cool
Have thought about going to a basic welding course at Lincoln though... in Ohio (??) Not far
