Kemppi Feed Kits FAQs

Straight answers to the questions people ask most when choosing and fitting a feed roll kit for a wire feeder.

Which roll groove do I need for steel, flux-cored or aluminium wire?

The groove shape is chosen to suit the wire. V-groove rolls are used for solid wire such as steel and stainless. V-knurled rolls, which have small teeth, suit flux-cored and metal-cored wire, because the tubular wire, filled with flux or metal powder, is softer and needs extra grip. U-groove rolls suit aluminium and other very soft wires, because the rounded groove feeds them without squashing them.

Using the wrong type is a common cause of slipping, shaving or crushed wire.

What is the difference between standard and heavy duty feed roll kits?

In many kit tables, standard feed roll kits are fitted with plastic rolls and heavy duty kits with metal rolls, listed by wire type and diameter. The exact difference depends on the maker and the feeder, and the groove shape for your wire matters more than the roll material.

Do not assume a heavy duty kit can replace a standard one or the other way round. Check the kit description, the data plate and your feeder manual, and fit the type the manual lists for your feeder and wire.

How tight should I set the drive roll pressure?

Use the least pressure that feeds the wire without slipping. Too much pressure can flatten or deform the wire, which leads to arc instability or burn-back and sheds shavings into the liner. Too little lets the rolls slide over the wire.

A commonly used method is to release the tension, feed the wire against a piece of wood, and tighten until the wire stops slipping, then add about half a turn. Reset the pressure every time you change the rolls or the wire.

Is a four-roll feeder better than a two-roll feeder?

A four-roll drive spreads the pushing force over more points, so each roll can apply less pressure. That is often helpful with soft wires, flux-cored wire, long cables and heavier-duty work. A two-roll drive is simpler and works well for many everyday jobs.

You cannot usually swap between the two types by changing the kit alone, because the feeder itself is built for one or the other. Choose the kit made for your feeder.
