ChuckE2009 just posted a video called: StickWeld 250 Torture Test + Full Review -

If you start viewing at 13 minutes and then the rest of the video you'll see what running bead practice looks like.

I'm a noob at this too and I thought I was doing good at practice time but I'm still working my way through a 10lb box of 1/8 7018. I've been burning other electrodes and wire too so I might have burned through this box by now if not for that. Not sure I could do a whole box in one sitting. :-) Going to have to look at adding machines with higher duty cycles to my collection I guess.
