Very cool butt welding technique

Thats Fitzee making the videos? I like him. I think he does usually wear a helmet..... just trying to weld and make a video at the same time. A lot of guys make videos that way and/or dont wear a proper respirator so that they can still talk. But yes, Safety first.

I use a piece of copper pipe. Whatever size laying around. Pound it flat on the end and bend it whatever way you like to fit behind a hole for plug welding. Hold it with gloves because it gets hot quick. Sometimes its get a bit stuck when welding hot. Just gotta wiggle it loose. Not sure if its a major issue if there is a little bit of copper stuck to the weld on the inside.
