Product Name
Leister (127.215 & 135.724) WeldPlast S2 and S2 PVC Extrusion Welders
Brief Description
The Leister WeldPlast S2 and S2 PVC are compact, digitally controlled hand-held extrusion welders designed for joining various thermoplastic materials. The WeldPlast S2 is versatile for common plastics like PE and PP, while the WeldPlast S2 PVC (135.724) is specifically optimized for PVC-U, featuring enhanced corrosion protection and a dedicated extrusion menu for superior PVC welding results.
Popular Applications & Uses
- Plastic tank fabrication- Pipe and tube welding in plumbing and industrial projects- Geomembrane installation and repair for landfills, mining, ponds, reservoirs, and canals- Civil engineering applications- Aquaculture construction and repair- Boat construction and repair- General plastic repairs and fabrication of plastic components- Joining plastic sheets and components in various construction applications- Roofing membranes

- Other Leister extrusion welders (e.g., WeldPlast S1, WeldPlast S4, Fusion series)- Hot gas welding tools (though extrusion welding generally provides stronger and faster bonds)- Generic plastic extrusion guns from other manufacturers
Comparison Note
The Leister WeldPlast S2 series stands out from traditional hot gas welding methods by offering superior control over welding parameters, resulting in stronger, more consistent bonds and faster processing times. The S2 PVC model is uniquely engineered with specific features like corrosion protection and a PVC-optimized extrusion menu, making it particularly effective for demanding PVC-U applications. Its compact and ergonomic design, coupled with a 360° rotating welding shoe, allows for exceptional maneuverability and the ability to weld in hard-to-reach areas, surpassing the capabilities of many traditional extruders. The digital display and integrated programs simplify operation, making it suitable for both professionals and those with less experience.
