Magna Wire Electrode Kit - Replaces the outer nose and central electrode on the (31123) and (31041) Stud Welders to install the Magna Wire. The Magna Wire (31181) is welded along a crease to make pulling easy with either the Magna Clamp (31183) with your frame machine or with the 5-Finger Magna Claw (31180). The Magna Claw can be used with a slide hammer, frame machine, or by hand with the screw-in handle.
