WIRE WELDING Drive rolls

V-groove:

The groove walls are smooth and these drive rolls are used for all solid vires except aluminium.

U-grove:

These drive rolls prevents deformation and are specially designed for Aluminium which is soft and will be deformed when sufficient pressure for steady feeding is applied with a V-groove drive roll. This may result in poor welding results.

Knurled V-groove:

These drive rolls are specially developed for flux-cored wires and provides excellent grip on the hard surface of these wires without requiring a pressure that will deform these tubular wires.
