Spent a full Friday trying to get a clean bead on a 2-inch schedule 80 elbow with my old Lincoln welder.
The joint kept cooling too fast until I finally tried a preheat with a rosebud tip, which worked perfectly, so what's your go-to method for tricky pipe welds?

Honestly I never preheat for schedule 80, that's overkill lol. Just crank your amps up a bit and run a tight arc, maybe a quick tack with a hotter setting. Letting the pipe suck heat is part of the process, you just have to move faster. A rosebud seems like a lot of extra work for a two inch fitting.

Your weld must look like a bird's nest.
