In the market for a new electrode holder on the buzz box. Spring-jaws style or screw-clamp style? I have the spring-jaws style, it's a little loose and sloppy but that could be because I've dropped it a few too many times.
I have a new one, not sure of brand or anything, I haven't put in on my welder yet because of how stiff the spring is, so you might check out a new spring style and it might hold better than you expect.
