MasterLiner Wire Feeding Conduit


The Best in Robotic Wire Feeding
The MasterLiner series set new robotic wire feeding standards. Made from individual segments, each turnable by 360°, MasterLiner segment feature four small rollers in every segment to guarantee smooth wire feeding with almost no resistance. This allows no further wire feeders to be required, even over longer distances.
The MasterLiner system is available as MasterLiner and MasterLiner MAXI both in FLEX and HD versions. The FLEX version is made up of a corrugated hose and connection system and enables a configuration of the exact required length. It is also repairable in the field, saving time and money with a reliable automated wire feeding solution. The heavy-duty HD version is fitted with resistant aramid-reinforced protection for extreme applications.
MasterLiner Features & Benefits:
- Low friction forces and a long lifetime
- Ultrasonic cleaning, maintenance free, and prone to little interference
- Wire feeding over long distances and by only one robot wire feeder
- Suitable for all robotic welding systems with wire feeding, including laser welding and brazing
- Easy and quick assembly and exchange possible by using quick connectors
MasterLiner Features at a Glance:
Clean Connect with Wire Rollers

End fitting provides for a quick and clean connection to the outer hose. The four roller sections produce virtually no friction and are built for short connections between individual segments to avoid wire feed issues.
Quickconnector for Tool-free Assembly

Quickconnector for MasterLiner MAXI offers tool-free assembly and disassembly of the MasterLiner via a spring-loaded locking mechanism that can be saved by turning the outer sleeve against accidental pulling.
Sensor & Inching Accessories Improve Feed

Wire end sensor signals the upcoming end of the wire inside the drum for fast replacement. The wire inching tool allows for the wire to be threaded quickly from the drum to the wire feed hose without manual threading.
