Jan, The standard and long (high production) Jump Ringers will
cut from 30 to 12 guage wire.
I can easily cut 15ga (.0571), but for 14ga (.0641) I have to scoot
the blade to slightly off center. I haven't been able to get
consistent cuts on anything larger - I often have to finish the cut
with a hand saw. What am I doing wrong? I'd love to be able to
