Rolliner 3G - up to 1,6 mm wire diameter and no tools needed for assembling

Rolliner 3G is the continuation of the roll-guided wire feed hose, which has been successful for 10 years, with significant improvements. The individual elements contain a pair of rollers and are connected to one another via joints. Each element is turned by 90 ° to the adjacent element, whereby the welding wire is guided entirely by rollers. As a result, the friction is significantly reduced in comparison to conventional wire guide hoses. Between the individual pairs of rollers there is a conical guide, which during threading leads the wire to the next pair of rollers, thus ensuring trouble-free threading over narrow radii.

  • Due to its low friction, Rolliner 3G allows significantly longer wire runs between the pay-off pack and the wire feeder. In many cases it is possible to avoid additional drives.
  • Rolliner 3G is not a wearing part and is maintenance-free for several years. The welding process becomes more stable as less slippage occurs due to the low forces in the wire transport system.
  • Rolliner 3G can be shortened or extended without tools. For shorting the use of a separation tool is recommended.

The inlets and outlets of the Rolliner 3G have a 1/4 "internal thread and a 1/2" external thread. As a result, the CRNG20 or CRNG40 quick couplings can be used.

Wire end controlsdrum connectors and decoiling aids can be easily used.


  • Insert elements into protective hose
  • Insert the holding clips at the inlet and outlet
  • Connect the wire inlet and outlet 

When inserting the housings into the protective sleeve, observe the directional arrows printed on the housings.

Disconnect housings

A separation tool is available for easier separation of the housings.
