Kemppi VK2.0 Drive Roll Kit Duratorque #1

HELP CHOOSING THE RIGHT DRIVE ROLLER
The three types of drive rollers most commonly used for wire welding processes are:
- V-knurled (VK)
- V-groove (V)
- U-groove (U)

V-knurled drive rollers are used with gas-shielded and self-shielded flux-cored and metal-cored wires, which are softer due to the flux inside and the tubular design. This type of drive roll has teeth to dig into the wire and help push it through the feeder drive system and gun cable. V-knurled drive rolls are not typically used with solid wire and may cause shavings to break off the wire. Those shavings can clog the liner and negatively impact wire feeding.

V-groove drive rollers are normally used with solid wire. The extra push provided by V-knurled drive rollers is not needed with solid wire, which is stiffer and tends to feed better through the liner.

U-groove drive rollers are designed for use with aluminium wires or other very soft materials. When using soft wires such as aluminium,it’s important to avoid marring the wire surface or deforming or mashing the wire. A U-groove drive roller helps to feed the wire through the liner while still keeping the wire’s round shape. There’s also a fourth, less common, type: U-cogged drive rollers. These are similar to V-knurled drive rollers in that they have teeth to feed soft wires. U-cogged drive rollers can be used to feed very large diameter, very soft cored wires.
