only thing i would suggest is a 22minute video is quite long, perhaps consider making it part one, and part 2?
Only saying is i am much more likely to watch a number of shorter vids like this than one long one, others might not agree though. you could split that video at the 11minute mark, then your talking about setup and stuff before hand, then actual welding in part 2.
otherwise, not bad for first go, perhaps try a microphone or something to make your voice a bit clearer.
lovely machine by the way, i am about to drop money on a r-tech mig. I have an r-tech arc and its lovely.
