This detailed product description presents the professional welding accessory from Wieländer+Schill, the PTFE inner liner with part number 337108, which is specially optimized for MIG (MAG) welding processes. This component is crucial for the stable and reliable transmission of the welding wire from the wire feeder to the end of the welding torch.
The product is a high-quality, PTFE (Polytetrafluoroethylene) liner (also known as inner wire guide tube), which is placed inside the welding torch cable. The outstanding low-friction properties of the PTFE material ensure the minimal resistance passage of the welding wire, which is essential for continuous and even arc maintenance.
This specific model with a length of 3.5 meters has, and red is color-coded, which aids in quick identification in the workshop environment. A specialty of the product is that it is equipped with a built-in 22 cm copper spiral This copper spiral provides additional mechanical stability and extra guidance for the wire, especially near the torch neck area, where it is most prone to breakage or increased resistance due to friction.
Although the description mentions the „Plastic liner in black”, based on the product name and visual identification, this specific version reinforced with a copper spiral is intended with the given specifications (3.5 m, red). The purpose of the liner is to minimize the friction between the wire and the inner wall of the tube, thereby reducing the risk of malfunctions and increasing welding efficiency.
To maintain stable wire feeding, the manufacturer recommends regular replacement of the liners, as the inner surface wears out during continuous use, which can impede wire movement.
Superior Wire Feeding: The PTFE material provides an extremely low coefficient of friction, which guarantees the smooth and unimpeded flow of the welding wire.
Reinforced Structure: The built-in 22 cm copper spiral offers extra rigidity and protection on the section of the cable that is subject to the highest stress.
Wide Compatibility: Specially designed for welding wires with diameters of 1.0 mm and 1.2 mm, ideal for frequent body repair applications.
Length: The 3.5 meter length ensures adequate flexibility for most standard MIG/MAG torches.
Color Coding: The red color facilitates quick visual identification among liners designated for different wire sizes or types.
The precise technical parameters of the product ensure compatibility and reliable performance with Wieländer+Schill systems and other compatible MIG/MAG equipment.

This PTFE liner is an essential accessory for gas-shielded arc welding, especially in industrial and workshop environments where frequent torch wire replacement and continuous, uninterrupted operation are crucial. The copper spiral design is particularly advantageous for longer torch cables or in working environments where the cable is subjected to significant bending.
Maintenance Importance: The most common cause of welding wire feeding problems (e.g., stuttering, wire rollback) is the wear of the inner liner. The surface of the liner wears out over time, or welding slag and dust may accumulate on it. Regular, proactive replacement of the 3.5-meter long liner reinforced with a copper spiral ensures optimal performance of the welding equipment and extends the lifespan of the torch.
The following accessories are also available related to the product for complete maintenance and professional installation:
O-ring for PTFE liners (Part No.: 337143): This component ensures the sealing and fixing of the liner in the correct position inside the torch or wire feeding unit, preventing movement and air ingress.
Copper spiral | 22 cm (Part No.: 337110): This item is likely the replaceable, separate copper spiral used to reinforce the liner, in case the original spiral gets damaged, or if a different type of liner needs reinforcement.
The combined use of these components guarantees the professional quality represented by Wieländer+Schill in the field of body repair technologies.
