Product Name
Leister (119.200 & 150.102) Fusion 2 Extrusion Welder
Brief Description
The Leister Fusion 2 is a compact, lightweight, and ergonomic handheld extrusion welder designed for joining thermoplastics, particularly PE (Polyethylene) and PP (Polypropylene). It is known for its ease of use, robust design, and ability to produce high-quality, strong welds in thick plastic sections. This tool is ideal for site work and applications requiring welding in confined spaces.
Popular Applications & Uses
- Plastic tank fabrication and container construction- Plastic pipe welding in plumbing, industrial piping, and infrastructure projects- Geomembrane installation and repair for environmental containment, landfill sites, reservoirs, canals, and pond waterproofing- Waterproofing applications, including tunnels- General plastic repairs and fabrication of plastic components- Boat construction and repair- Joining plastic sheets and components in construction- Fabrication of land drainage systems, sump tanks, and manways- Welding thick-section fabrications where large volume, homogeneous seams are needed in a single pass
Industries that Commonly Use It
- Plastic Fabrication- Construction/Building Services (including roofing, flooring, and civil engineering)- Marine (for boat construction and repair)- Environmental Engineering (for geomembrane installation and containment systems)- Water Management and Wastewater Treatment- Industrial Fabrication- Transportation/Specialty Vehicle (for plastic component repair and fabrication)- Agriculture (for land drainage systems)
Special and Unique Features
- Compact and handy design, measuring only 450mm (17.7 inches) long, making it one of the shortest in its performance class and ideal for tight spaces- Lightweight at 5.9 kg (13 lbs) for extended use- Motor start-up protection prevents cold starts and equipment damage- Dual-sided, twist-free welding rod intake- 360° rotatable welding shoe for enhanced user flexibility and ease of access- Integrated electronics allow stepless adjustment of preheating temperature and output quantity- Robust and simplistic design for easy operation- Integrated hot air blower eliminates the need for an external air source- Ergonomic design for comfortable handling

Known backups / known substitutes
- **Other Leister Extrusion Welders:** Leister WELDPLAST S1, WELDPLAST S2, FUSION 3C, FUSION 3- **Hot Air Welding Guns (Manual Tools):** Suitable for smaller fabrication work, detailed projects, repairs, and thinner plastics (3-5mm). Examples include Leister TRIAC ST and HOT JET S. These are generally slower for thick materials.- **Other Brands of Extrusion Welders:** Various manufacturers produce plastic extrusion welders for similar applications.
Comparison Note
The Leister Fusion 2 Extrusion Welder offers significant advantages over hot air welding guns for larger fabrication projects and thicker plastics, providing much faster welding times (5-6x faster) and stronger, more consistent welds in a single pass. Its compact size and lightweight nature make it particularly agile and suitable for working in tight spaces, a key differentiator even among other extrusion welders. While manual hot air tools are better for very small, detailed work or thin materials, the Fusion 2 excels in high-volume, high-strength plastic joining of thicker sections.
