The back-up electrode offers a round or rectangular welding surface. It offers great versatility with different dimensions such as 4RW or 5RW cone with a welding surface ranging from 1/2″ to 2″. It is also possible to have them made specifically for your needs.
When used with a pointed nose, a dome nose or a radius nose electrode, it provides a welded surface with minimal deformation.
This electrode is durable because it wears out much less quickly than a straight or double-bend electrode.
Can be used as much for welding wire or mesh as it is for welding a nut or threaded rod.
