How To Differentiate Welding Drive Rollers

In this video, we explain how to Differentiate between V, F and U Groove Welding Drive Rollers.

Starting off, “v” groove rollers are used for solid wire, these are not knurled and since it’s a stiffer wire, it won’t deform or slip as it’s feeding through.

Next, ‘F’ groove rollers are used for gasless wire, they are knurled and have teeth that dig into the wire so you don’t have to tension down as hard, keeping the wire in its tubular shape without distorting it.

Finally, ‘U’ groove rollers are designed for aluminium wire, since aluminium wire is soft and easy to deform, u groove rollers keep the wire in its round form, feeding smoothly.
