This detailed product description presents the high-quality, black plastic inner tube (liner) offered by Wieländer+Schill, specifically designed for MIG (Metal Inert Gas) welding applications. This component is crucial for the stable and reliable conveyance of the welding wire inside the welding torch.
The product is a 3.5-meter long, black plastic inner tube that resides inside the welding torch cable. Its main function is the precise and unobstructed guidance of the welding wire from the feeder to the welding point. Stable wire feeding is essential for continuous and quality welding; therefore, regular replacement of the inner tubes is recommended to minimize wear and friction.
The package also includes a 22 cm long copper spring, which further enhances the quality and stability of the wire guidance.
This liner is specifically designed to be compatible with 0.8 mm and 1.0 mm diameter welding wires, ensuring wide usability for various MIG welding tasks.
Superior Wire Feeding: The smooth inner surface minimizes friction, ensuring an even and reliable flow of the welding wire, which is essential for the stability of the welding process.
Wide Compatibility: Supports the most common wire diameters (0.8 mm and 1.0 mm), providing flexibility for the user.
Durability: The combination of quality plastic and copper materials guarantees a long service life under normal operating conditions.
Complete Solution: The included 22 cm copper spring provides extra support for wire guidance, especially near the torch end.
Preventive Maintenance: Regular replacement prevents welding defects that can result from wire jamming caused by a worn or damaged inner tube.

The inner tube (liner) is designed to be installed inside the welding torch cable, between the wire feed unit and the welding head. When replacing, care must be taken to ensure the liner is not kinked or twisted, as this can impede wire movement. The 3.5-meter length ensures suitability for most standard MIG torch cables.
For stable operation, it is recommended to follow the specifications of the welding equipment manufacturer when replacing the liner.
In connection with the product, the following accessory is recommended for perfect sealing and fixation:
| Add-on | Part number | Description |
