Product Name
Leister 145.903 Welding shoe complete (FWP-Int. Air) V-seam 15 and X-seam 30mm
Brief Description
This is a specialized welding shoe accessory for Leister plastic extrusion welders, designed to create precise V-seam (15mm) and X-seam (30mm) weld geometries. It features internal air guidance, ensuring optimal preheating of the weld area for strong, homogeneous plastic welds.
Popular Applications & Uses
- Joining thermoplastic materials in various fabrication and repair tasks.- Fabrication and repair of plastic tanks and containment vessels.- Construction and repair in boat building.- Installation of geomembranes in landfill projects, earthworks, hydraulic engineering, and tunnel construction.- Welding of plastic components in vehicle repairs, such as bumpers and wheel well liners.- Processing of tarpaulins and plastic sealing sheets.- Installation of plastic floor coverings.- Manufacturing of plastic pipes and fittings.
Industries that Commonly Use It
- Plastic Fabrication- Construction/ Building Services- Marine- Automotive Service/Repair- Chemical Industry- Flooring Installer or Manufacturer- Tarp, Fabric, Awning Manufacturing- Packaging Services or Contractor- Distributers & Resellers
Special and Unique Features
- Internal Air Guidance (FWP-Int. Air): Ensures efficient and consistent preheating of the weld area from within the shoe, crucial for high-quality plastic welds.- Dual Seam Geometry: Capable of producing both V-seam (15mm) and X-seam (30mm) welds, offering versatility for different joint configurations.- Precision Welding: Designed for Leister extrusion welders, known for achieving strong, homogeneous, and sealed plastic joints.- Durable Construction: Leister accessories are built for industrial use and durability.- Easy to Install: Simple and easy to use with compatible Leister FUSION and WELDPLAST series extrusion welders.

Known backups / known substitutes
- Other Leister welding shoes with different geometries (e.g., fillet weld, corner seams, other V-seam/X-seam sizes).- Leister offers a wide range of welding shoes for various applications and extrusion welders.- Generic or third-party welding shoes designed for Leister extrusion welders, though Leister brand is known for quality.
Comparison Note
This specific welding shoe is distinguished by its internal air guidance and its ability to produce both 15mm V-seams and 30mm X-seams, making it suitable for applications requiring strong butt welds on thicker plastic materials. Unlike external air guide shoes, internal air guidance ensures more focused and efficient preheating. Its specialized geometry allows for robust joints in comparison to simpler fillet or lap welds, particularly where high resiliency and a strong, homogeneous welding seam are required.
